In the present functional magnetic resonance imaging study, neural correlates of three hypothesized components of remembering were explored, including those associated with control, perceived oldness, and retrieved content. Levels of each component were separately manipulated by varying study procedures and sorting trials by subject response. Results suggest that specific regions in the left prefrontal cortex, including anterior-ventral Brodmann's Area (BA) 45/47 and more dorsal BA 44, increase activity when high levels of control are required but do not necessarily modulate on the basis of perceived oldness. Parietal and frontal regions, particularly the left parietal cortex near BA 40/39, associate with the perception that information is old and generalize across levels of control and retrieved content. Activity in the parietal cortex correlated with perceived oldness even when judgments were in error. The inferior temporal cortex near BA 19/37 associated differentially with retrieval of visual object content.

In this paper, we propose a new calibration method for the texture mapping; the method utilizes reflectance images and iterative pose estimation based on a robust M-estimator.","owner":{"id":13002112,"first_name":"Mark","middle_initials":null,"last_name":"Wheeler","page_name":"MarkWheeler","domain_name":"londonmet","created_at":"2014-06-16T18:16:33.662-07:00","display_name":"Mark Wheeler","url":"https://londonmet.academia.edu/MarkWheeler"},"attachments":[{"id":103286196,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/103286196/thumbnails/1.jpg","file_name":"0008.pdf","download_url":"https://www.academia.edu/attachments/103286196/download_file?st=MTczNDE3MjIxNCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Mapping_textures_on_3D_geometric_model_u.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/103286196/0008-libre.pdf?1686556982=\u0026response-content-disposition=attachment%3B+filename%3DMapping_textures_on_3D_geometric_model_u.pdf\u0026Expires=1734175814\u0026Signature=Z6sUMOuBJnBuq2jcq2491vU~6g9RQmSbAiSjgEkEO51nQw-e6HJcqvWwJ87M2LfjGbKhwNeT3HKl8Kjg5yfUQFonDdmYGVjVVuwoDfZUaaRr9~8ocWFogXdLIrPrGGIBdh5DxW5UaaPe5c~93B0jkACWwultjUuMqENFV-LcX-dbsKmru-bnvo8rXlfElMUJx6dbJmws4xxrWeZNvF56gmMm7fWi5YEp~ABs1h4n73ppmZ4edEnxeaCanlnRx4hKLD3q24UJNx2I~aQJdKpWqvTEHF8s5gjjeqq1TrqBTpKj5AdDg~qpbwiCyNglQoSqYvayALckMwQ0pCUTRzCU9w__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":422,"name":"Computer Science","url":"https://www.academia.edu/Documents/in/Computer_Science"},{"id":465,"name":"Artificial Intelligence","url":"https://www.academia.edu/Documents/in/Artificial_Intelligence"},{"id":854,"name":"Computer Vision","url":"https://www.academia.edu/Documents/in/Computer_Vision"},{"id":50642,"name":"Virtual Reality","url":"https://www.academia.edu/Documents/in/Virtual_Reality"},{"id":61108,"name":"Geometric model","url":"https://www.academia.edu/Documents/in/Geometric_model"},{"id":187345,"name":"Color Image","url":"https://www.academia.edu/Documents/in/Color_Image"},{"id":230436,"name":"Pose Estimation","url":"https://www.academia.edu/Documents/in/Pose_Estimation"},{"id":1752153,"name":"Texture Mapping","url":"https://www.academia.edu/Documents/in/Texture_Mapping"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="103222532"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/103222532/Travel_notes_a_Liberian_medical_experience"><img alt="Research paper thumbnail of Travel notes: a Liberian medical experience" class="work-thumbnail" src="https://attachments.academia-assets.com/103286198/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/103222532/Travel_notes_a_Liberian_medical_experience">Travel notes: a Liberian medical experience</a></div><div class="wp-workCard_item"><span>The Yale journal of biology and medicine</span><span>, 1975</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">The delivery of even the simplest form of health care has three prerequisites: a population to wh...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">The delivery of even the simplest form of health care has three prerequisites: a population to whom the health care can be delivered, a knowledge of the type of care to deliver, and a means of delivery.

Given that slow-wave sleep significantly declines with age, we hypothesize that age-related chang...","owner":{"id":13002112,"first_name":"Mark","middle_initials":null,"last_name":"Wheeler","page_name":"MarkWheeler","domain_name":"londonmet","created_at":"2014-06-16T18:16:33.662-07:00","display_name":"Mark Wheeler","url":"https://londonmet.academia.edu/MarkWheeler"},"attachments":[{"id":103286191,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/103286191/thumbnails/1.jpg","file_name":"624795.pdf","download_url":"https://www.academia.edu/attachments/103286191/download_file?st=MTczNDE3MjIxNCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Age_related_decline_in_controlled_retrie.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/103286191/624795-libre.pdf?1686556988=\u0026response-content-disposition=attachment%3B+filename%3DAge_related_decline_in_controlled_retrie.pdf\u0026Expires=1734175814\u0026Signature=geGi4UtPmRQpnUr-Z0rb5cdr-NvsfG-7H6~3U~NYLnxx9iy44-OmD8rFGHK7AGFkFiMvcofKzHRFWaLb8m1g3n5jIsdWeu3zghnQ-1JrmYeRdJroiEMBBeI-C08mOEtLSXRZ691l07yXeBDTqU56pIN2cKKQ5C1zZe~ZNKG0pL6hlDL~9cbsMH-v6x4CW89whVIhDBD5GL6x~tFFfmVA2w1OD2A1QbcAdu7KhvHG87NOxy27SjT3ou~FfSzwvqkxL0kYFfz7abEdDysmpcQIvaxC9gMS38fCJvJE2w1RHr7Q9CQRwug8wFZtQVlau0oTyO3z0~D0sb7j0vlvwbspqQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":221,"name":"Psychology","url":"https://www.academia.edu/Documents/in/Psychology"},{"id":4212,"name":"Cognition","url":"https://www.academia.edu/Documents/in/Cognition"},{"id":6791,"name":"Aging","url":"https://www.academia.edu/Documents/in/Aging"},{"id":8538,"name":"Working Memory","url":"https://www.academia.edu/Documents/in/Working_Memory"},{"id":26327,"name":"Medicine","url":"https://www.academia.edu/Documents/in/Medicine"},{"id":28576,"name":"Prefrontal Cortex","url":"https://www.academia.edu/Documents/in/Prefrontal_Cortex"},{"id":33732,"name":"Executive Function","url":"https://www.academia.edu/Documents/in/Executive_Function"},{"id":46858,"name":"Memory","url":"https://www.academia.edu/Documents/in/Memory"},{"id":133057,"name":"Young Adult","url":"https://www.academia.edu/Documents/in/Young_Adult"},{"id":133324,"name":"Sleep","url":"https://www.academia.edu/Documents/in/Sleep"},{"id":133722,"name":"Executive Functions","url":"https://www.academia.edu/Documents/in/Executive_Functions"},{"id":240756,"name":"Neural plasticity","url":"https://www.academia.edu/Documents/in/Neural_plasticity"},{"id":289271,"name":"Aged","url":"https://www.academia.edu/Documents/in/Aged"},{"id":1627527,"name":"Cognition disorders","url":"https://www.academia.edu/Documents/in/Cognition_disorders"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="103222528"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/103222528/_title_Negative_permittivity_and_permeability_in_the_infrared_due_to_dielectric_spheres_title_"><img alt="Research paper thumbnail of <title>Negative permittivity and permeability in the infrared due to dielectric spheres</title>" class="work-thumbnail" src="https://attachments.academia-assets.com/103286190/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/103222528/_title_Negative_permittivity_and_permeability_in_the_infrared_due_to_dielectric_spheres_title_"><title>Negative permittivity and permeability in the infrared due to dielectric spheres</title></a></div><div class="wp-workCard_item"><span>Photonic Applications in Nonlinear Optics, Nanophotonics, and Microwave Photonics</span><span>, 2005</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">In this paper we consider the effective electric and magnetic properties of a three-dimensional c...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">In this paper we consider the effective electric and magnetic properties of a three-dimensional collection of nonmagnetic spheres.

During scanned testing, they made binary choices informed by the sum of the predictive strengths of individual shapes. Sequences of shapes adhered to three distinct rates of evidence (RoEs): rapid, gradual, and switch. We predicted that activity in regions informing the decision would modulate as a function of RoE prior to the choice.

In this review, the authors discuss this and other related capabilities, considering evidence from such diverse sources as brain imaging, neuropsychological experiments, clinical observations, and developmental psychology. The evidence supports a preliminary theory of episodic remembering, which holds that the prefrontal cortex plays a critical, supervisory role in empowering healthy adults with autonoetic consciousness-the capacity to mentally represent and become aware of subjective experiences in the past, present, and future. When a rememberer mentally travels back in subjective time to re-experience his or her personal past, the result is an act of retrieval from episodic memory. One of the most fascinating achievements of the human mind is the ability to mentally travel through time. It is somehow possible for a person to relive experiences by thinking back to previous situations and happenings in the past and to mentally project oneself into the anticipated future through imagination, daydreams, and fantasies. In the everyday world, the most common manifestation of this ability can be referred to as \"remembering past happenings.\" Everyone knows what this phrase means and what it is like to reflect on personal experiences, past or future, that are not part of the present. Although mental time travel is clearly related to memory, it is interesting that in very few of the countless articles, chapters, and books that have been written on the topic of memory have researchers paid attention to the conscious act of remembering personal experiences. Of course, there have been some notable exceptions to this claim. In general, most models and theories of memory focus on the structures or processes by which information is encoded, stored, or retrieved, with little interest to the actual experience of remembering. We propose that the ability to mentally travel through time is an expression of the episodic memory system of the brain and that this ability is not shared by other systems of memory.

The materials used are entirely non-magnetic. The Mie scattering theory of the constituent spheres is used in the effective medium theory.

STATEMENT OF THE CASE Ms. THURSDAY BRAM'S CONVICTION Ms. Thursday Brain worked for Mr. Maxwell Smith as his secretary and occasional housekeeper of the Galisteo House for approximately nine years before she was convicted of three counts of theft of an object of cultural heritage from a museum, in violation of the Theft of Major Artwork Act ("TOMAA"). R. at 1, 2, 4. Ms. Bram also undertook occasional curatorial duties, including the cataloguing of Mr. Smith's collection, housed within the Foundation's Galisteo House. Id. at 4. Additionally, Ms. Brain sometimes escorted visitors around the grounds of Galisteo House. Id. In June 2008, Ms. Brain admitted to stealing five missing items during July and August 2007-while Mr. Smith was on an extended trip abroad-after Mr. Smith caught her in the act of removing a pair of skis used on a 1911 expedition to the South Pole. Id. at 5. All five of the stolen artifacts were found in Ms. Brain's cottage and private cabin. Id. She was charged for the theft of a letter from Friar Marcos de Niza, dated 1539; a scrimshaw whale's tooth fashioned by James Adolphus Bute during Charles Darwin's voyage of the HMS Beagle; and an updated wall map of the United States by Osgood Carleton, with possible ties to the Lewis and Clark expedition."

In the present functional magnetic resonance imaging study, neural correlates of three hypothesized components of remembering were explored, including those associated with control, perceived oldness, and retrieved content. Levels of each component were separately manipulated by varying study procedures and sorting trials by subject response. Results suggest that specific regions in the left prefrontal cortex, including anterior-ventral Brodmann's Area (BA) 45/47 and more dorsal BA 44, increase activity when high levels of control are required but do not necessarily modulate on the basis of perceived oldness. Parietal and frontal regions, particularly the left parietal cortex near BA 40/39, associate with the perception that information is old and generalize across levels of control and retrieved content. Activity in the parietal cortex correlated with perceived oldness even when judgments were in error. The inferior temporal cortex near BA 19/37 associated differentially with retrieval of visual object content.

In this paper, we propose a new calibration method for the texture mapping; the method utilizes reflectance images and iterative pose estimation based on a robust M-estimator.","owner":{"id":13002112,"first_name":"Mark","middle_initials":null,"last_name":"Wheeler","page_name":"MarkWheeler","domain_name":"londonmet","created_at":"2014-06-16T18:16:33.662-07:00","display_name":"Mark Wheeler","url":"https://londonmet.academia.edu/MarkWheeler"},"attachments":[{"id":103286196,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/103286196/thumbnails/1.jpg","file_name":"0008.pdf","download_url":"https://www.academia.edu/attachments/103286196/download_file?st=MTczNDE3MjIxNCw4LjIyMi4yMDguMTQ2&st=MTczNDE3MjIxNCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Mapping_textures_on_3D_geometric_model_u.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/103286196/0008-libre.pdf?1686556982=\u0026response-content-disposition=attachment%3B+filename%3DMapping_textures_on_3D_geometric_model_u.pdf\u0026Expires=1734175814\u0026Signature=Z6sUMOuBJnBuq2jcq2491vU~6g9RQmSbAiSjgEkEO51nQw-e6HJcqvWwJ87M2LfjGbKhwNeT3HKl8Kjg5yfUQFonDdmYGVjVVuwoDfZUaaRr9~8ocWFogXdLIrPrGGIBdh5DxW5UaaPe5c~93B0jkACWwultjUuMqENFV-LcX-dbsKmru-bnvo8rXlfElMUJx6dbJmws4xxrWeZNvF56gmMm7fWi5YEp~ABs1h4n73ppmZ4edEnxeaCanlnRx4hKLD3q24UJNx2I~aQJdKpWqvTEHF8s5gjjeqq1TrqBTpKj5AdDg~qpbwiCyNglQoSqYvayALckMwQ0pCUTRzCU9w__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":422,"name":"Computer Science","url":"https://www.academia.edu/Documents/in/Computer_Science"},{"id":465,"name":"Artificial Intelligence","url":"https://www.academia.edu/Documents/in/Artificial_Intelligence"},{"id":854,"name":"Computer Vision","url":"https://www.academia.edu/Documents/in/Computer_Vision"},{"id":50642,"name":"Virtual Reality","url":"https://www.academia.edu/Documents/in/Virtual_Reality"},{"id":61108,"name":"Geometric model","url":"https://www.academia.edu/Documents/in/Geometric_model"},{"id":187345,"name":"Color Image","url":"https://www.academia.edu/Documents/in/Color_Image"},{"id":230436,"name":"Pose Estimation","url":"https://www.academia.edu/Documents/in/Pose_Estimation"},{"id":1752153,"name":"Texture Mapping","url":"https://www.academia.edu/Documents/in/Texture_Mapping"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="103222532"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/103222532/Travel_notes_a_Liberian_medical_experience"><img alt="Research paper thumbnail of Travel notes: a Liberian medical experience" class="work-thumbnail" src="https://attachments.academia-assets.com/103286198/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/103222532/Travel_notes_a_Liberian_medical_experience">Travel notes: a Liberian medical experience</a></div><div class="wp-workCard_item"><span>The Yale journal of biology and medicine</span><span>, 1975</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">The delivery of even the simplest form of health care has three prerequisites: a population to wh...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">The delivery of even the simplest form of health care has three prerequisites: a population to whom the health care can be delivered, a knowledge of the type of care to deliver, and a means of delivery.

The sleep literature points to the importance of slow-wave sleep in restoration of prefrontal cortex function. Given that slow-wave sleep significantly declines with age, we hypothesize that age-related chang...","owner":{"id":13002112,"first_name":"Mark","middle_initials":null,"last_name":"Wheeler","page_name":"MarkWheeler","domain_name":"londonmet","created_at":"2014-06-16T18:16:33.662-07:00","display_name":"Mark Wheeler","url":"https://londonmet.academia.edu/MarkWheeler"},"attachments":[{"id":103286191,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/103286191/thumbnails/1.jpg","file_name":"624795.pdf","download_url":"https://www.academia.edu/attachments/103286191/download_file?st=MTczNDE3MjIxNCw4LjIyMi4yMDguMTQ2&st=MTczNDE3MjIxNCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Age_related_decline_in_controlled_retrie.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/103286191/624795-libre.pdf?1686556988=\u0026response-content-disposition=attachment%3B+filename%3DAge_related_decline_in_controlled_retrie.pdf\u0026Expires=1734175814\u0026Signature=geGi4UtPmRQpnUr-Z0rb5cdr-NvsfG-7H6~3U~NYLnxx9iy44-OmD8rFGHK7AGFkFiMvcofKzHRFWaLb8m1g3n5jIsdWeu3zghnQ-1JrmYeRdJroiEMBBeI-C08mOEtLSXRZ691l07yXeBDTqU56pIN2cKKQ5C1zZe~ZNKG0pL6hlDL~9cbsMH-v6x4CW89whVIhDBD5GL6x~tFFfmVA2w1OD2A1QbcAdu7KhvHG87NOxy27SjT3ou~FfSzwvqkxL0kYFfz7abEdDysmpcQIvaxC9gMS38fCJvJE2w1RHr7Q9CQRwug8wFZtQVlau0oTyO3z0~D0sb7j0vlvwbspqQ__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":221,"name":"Psychology","url":"https://www.academia.edu/Documents/in/Psychology"},{"id":4212,"name":"Cognition","url":"https://www.academia.edu/Documents/in/Cognition"},{"id":6791,"name":"Aging","url":"https://www.academia.edu/Documents/in/Aging"},{"id":8538,"name":"Working Memory","url":"https://www.academia.edu/Documents/in/Working_Memory"},{"id":26327,"name":"Medicine","url":"https://www.academia.edu/Documents/in/Medicine"},{"id":28576,"name":"Prefrontal Cortex","url":"https://www.academia.edu/Documents/in/Prefrontal_Cortex"},{"id":33732,"name":"Executive Function","url":"https://www.academia.edu/Documents/in/Executive_Function"},{"id":46858,"name":"Memory","url":"https://www.academia.edu/Documents/in/Memory"},{"id":133057,"name":"Young Adult","url":"https://www.academia.edu/Documents/in/Young_Adult"},{"id":133324,"name":"Sleep","url":"https://www.academia.edu/Documents/in/Sleep"},{"id":133722,"name":"Executive Functions","url":"https://www.academia.edu/Documents/in/Executive_Functions"},{"id":240756,"name":"Neural plasticity","url":"https://www.academia.edu/Documents/in/Neural_plasticity"},{"id":289271,"name":"Aged","url":"https://www.academia.edu/Documents/in/Aged"},{"id":1627527,"name":"Cognition disorders","url":"https://www.academia.edu/Documents/in/Cognition_disorders"}],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="103222528"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/103222528/_title_Negative_permittivity_and_permeability_in_the_infrared_due_to_dielectric_spheres_title_"><img alt="Research paper thumbnail of <title>Negative permittivity and permeability in the infrared due to dielectric spheres</title>" class="work-thumbnail" src="https://attachments.academia-assets.com/103286190/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/103222528/_title_Negative_permittivity_and_permeability_in_the_infrared_due_to_dielectric_spheres_title_"><title>Negative permittivity and permeability in the infrared due to dielectric spheres</title></a></div><div class="wp-workCard_item"><span>Photonic Applications in Nonlinear Optics, Nanophotonics, and Microwave Photonics</span><span>, 2005</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">In this paper we consider the effective electric and magnetic properties of a three-dimensional c...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">In this paper we consider the effective electric and magnetic properties of a three-dimensional collection of nonmagnetic spheres.

However, it is not known whether accumulating signals in human neuroimaging are related to the integration of evidence. Our aim was to determine whether activity accumulates in a nonperceptual task by identifying brain regions tracking the strength of probabilistic evidence. fMRI was used to measure whole-brain activity as choices were informed by integrating a series of learned prior probabilities. Participants first learned the predictive relationship between a set of shape stimuli and one of two choices. During scanned testing, they made binary choices informed by the sum of the predictive strengths of individual shapes.

In this review, the authors discuss this and other related capabilities, considering evidence from such diverse sources as brain imaging, neuropsychological experiments, clinical observations, and developmental psychology. The evidence supports a preliminary theory of episodic remembering, which holds that the prefrontal cortex plays a critical, supervisory role in empowering healthy adults with autonoetic consciousness-the capacity to mentally represent and become aware of subjective experiences in the past, present, and future. When a rememberer mentally travels back in subjective time to re-experience his or her personal past, the result is an act of retrieval from episodic memory. One of the most fascinating achievements of the human mind is the ability to mentally travel through time. It is somehow possible for a person to relive experiences by thinking back to previous situations and happenings in the past and to mentally project oneself into the anticipated future through imagination, daydreams, and fantasies. In the everyday world, the most common manifestation of this ability can be referred to as "remembering past happenings." Everyone knows what this phrase means and what it is like to reflect on personal experiences, past or future, that are not part of the present. Although mental time travel is clearly related to memory, it is interesting that in very few of the countless articles, chapters, and books that have been written on the topic of memory have researchers paid attention to the conscious act of remembering personal experiences. Of course, there have been some notable exceptions to this claim.

The existence of an anomalous dispersion region with a negative group velocity and the appropriate signs associated with the imaginary parts of the permittivity and permeability are also discussed.","owner":{"id":13002112,"first_name":"Mark","middle_initials":null,"last_name":"Wheeler","page_name":"MarkWheeler","domain_name":"londonmet","created_at":"2014-06-16T18:16:33.662-07:00","display_name":"Mark Wheeler","url":"https://londonmet.academia.edu/MarkWheeler"},"attachments":[{"id":103286186,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/103286186/thumbnails/1.jpg","file_name":"2005_20PRB_20Wheeler_20Magnetic_20Resp_20Optical_20Freq_20.pdf","download_url":"https://www.academia.edu/attachments/103286186/download_file?st=MTczNDE3MjIxNCw4LjIyMi4yMDguMTQ2&st=MTczNDE3MjIxNCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Three_dimensional_array_of_dielectric_sp.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/103286186/2005_20PRB_20Wheeler_20Magnetic_20Resp_20Optical_20Freq_20-libre.pdf?1686556984=\u0026response-content-disposition=attachment%3B+filename%3DThree_dimensional_array_of_dielectric_sp.pdf\u0026Expires=1734175814\u0026Signature=Phk5hHiSjzLQ91ThF82Ta6v7Qr4zasWdAzdVJ5ogDeBmg9POKq8Ox7K0U8Cvx6Y~zHMDUsB~ZIOwYRLY52RxmCgFPPtrFmDItQ7qq83Rr2iUxFCsM~0Gz5nlYvkFvidCzSBv20ut9xSV0E6yCsxIegxy6HKTP7i5Vs39fqSNlhzhZj6iqkCmFyq5xhljDxpH9wingNaNuoqSxmpvN5ccc1ExmDFMVpp7ocqcJYKQ1cIGyQ8ksrjBcODpqFRBqp3AVxXAdXxZWC83Q4GUyEv6o2qtzwGNhIB6pZq5XkYpfx3GKr6LZVUzJrPSuizJ8IBOzcKtHTs1TZAbi71c54ZWwg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":511,"name":"Materials Science","url":"https://www.academia.edu/Documents/in/Materials_Science"},{"id":102207,"name":"DIELECTRIC","url":"https://www.academia.edu/Documents/in/DIELECTRIC"},{"id":118582,"name":"Physical sciences","url":"https://www.academia.edu/Documents/in/Physical_sciences"},{"id":241527,"name":"Multiple Scattering","url":"https://www.academia.edu/Documents/in/Multiple_Scattering"},{"id":260118,"name":"CHEMICAL SCIENCES","url":"https://www.academia.edu/Documents/in/CHEMICAL_SCIENCES"},{"id":335361,"name":"Infrared","url":"https://www.academia.edu/Documents/in/Infrared"},{"id":504035,"name":"Three Dimensional","url":"https://www.academia.edu/Documents/in/Three_Dimensional"},{"id":976192,"name":"Spheres","url":"https://www.academia.edu/Documents/in/Spheres"},{"id":1427925,"name":"Effective Medium Theory","url":"https://www.academia.edu/Documents/in/Effective_Medium_Theory"},{"id":2353926,"name":"Isotropy","url":"https://www.academia.edu/Documents/in/Isotropy"},{"id":4105763,"name":"Group velocity","url":"https://www.academia.edu/Documents/in/Group_velocity"}],"urls":[{"id":32197010,"url":"http://link.aps.org/article/10.1103/PhysRevB.72.193103"}]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="103222515"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/103222515/Coated_nonmagnetic_spheres_with_a_negative_index_of_refraction_at_infrared_frequencies"><img alt="Research paper thumbnail of Coated nonmagnetic spheres with a negative index of refraction at infrared frequencies" class="work-thumbnail" src="https://attachments.academia-assets.com/103286183/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/103222515/Coated_nonmagnetic_spheres_with_a_negative_index_of_refraction_at_infrared_frequencies">Coated nonmagnetic spheres with a negative index of refraction at infrared frequencies</a></div><div class="wp-workCard_item"><span>Physical Review B</span><span>, 2006</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">A three-dimensional lattice of micron-scale coated spheres is shown to have an isotropic negative...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">A three-dimensional lattice of micron-scale coated spheres is shown to have an isotropic negative index of refraction at infrared frequencies.
