It allowed scientists to precisely control the activation of select neurons. Previously, scientists commonly used injections and implanted electrodes to control neurons. This was definitely a step up from some of the previous studies like lesioning. Metaphorically, lesioning is like trying to figure out the job of an individual ant in a colony by hitting the colony with a car and seeing what stops working. You end up affecting way too many ants. Electrodes and improved surgical techniques improved the resolution but were still fairly dull.

In previous experiments, sound waves were difficult to focus and ended up heating the tissue. By using lower frequency waves for short periods of time, the scientists found that they could hit the worms without any behavioral changes, indicating that the sound beam would not affect normal tissue. </span></p><br/><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 14.6667px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">The Receptor</span></p><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 14.6667px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">Suspecting a stretch sensitive ion channel, TRP-4, as the receptor sensing the ultrasound beam, the group found that animals lacking TRP-4 had reduced responses to the beam. The group then focused on two different neurons, both of which cause worms to reverse their direction. By creating transgenics that misexpressed TRP-4 in these sets of neurons, AWC and ASH, the scientists found that the transgenics increased their reversal behavior in response to the ultrasound beam, further indicating that TRP-4 was necessary to sense the ultrasound beam.</span></p><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 14.6667px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">Just for kicks, the group then misexpressed TRP-4 in neurons with previously unknown function and used the sound beam to figure out what they did.

They theorized they could inject these microbubbles into the vasculature of the brain, increasing the reach of the sound beam without having to increase the energy it delivers. . . this translates into more reach without cooking the brain.</span></p><br/><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 14.6667px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">The Take Home Message</span></p><br/><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 14.6667px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">There are a lot of things I left out, and there are clearly some hurdles that sonogenetics has to overcome, but this paper aims at producing a method of neuronal stimulation from outside the brain. That is what they did. Most current techniques require drilling into the skull, sonogenetics does not. Since the TRP-4 receptor isn’t present in mammals, it could hypothetically be introduced without interfering with existing brain circuitry. The ultrasound beam is steerable and it doesn’t damage tissue at low energies. If these low energies are not enough to activate TRP-4, microbubbles can be used to help amplify the sound.</span></p><br/><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 14.6667px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">This technique would still require generating transgenic organisms and steering and focusing the beam will still take some work. I couldn’t figure out whether or not the microbubbles would permeate the blood brain barrier, so I don’t know how easy it would be to amplify the signal. Sonogentics also has a long way to go to catch up to optogenetics. Using optogentics you can very precisely cause a neuron to fire. Using different colors and different receptors you can cause the same neuron to react in opposite ways. Again. . . precise control is the exciting thing about optogenetics. </span></p><br/><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 14.6667px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">But at the end of the day. . .</span></p><br/><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 14.6667px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">This is cool.</span></p><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 14.6667px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">As with many others, the ability to stimulate remotely stimulate neurons is key to my plans of world domination. In fairness, it is important for others with similar plans. Sonogenetics allows for that type of remote stimulation. </span></p><br/><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 14.6667px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">Final Thought</span></p><span style="font-size: 14.6667px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">In a discussion with one of my former students, currently at MIT, Michaela Ennis suggested the possibility of creating synthetic circuits. Imagine using sonogenetics to get a neuron to fire and glow green. This green light could then use optogentics to get a second neuron to fire which would then glow yellow. . . </span></span> </div> </div> </div> </div> </div> <div class="clearfix"> <div class="fright"> <a id="showCmntInBlog" name="showCmntInBlog" href="http://www.nature.com/scitable/blog/why-science-matters/sound_controls_mind_optogenetics#commentsId" class="inlineLinks hideForPrint"><span class="bold marginright5px">1 Comment </span></a> </div> </div> <div class="cleartboth"></div> </div> <hr class="thinGreyBlog"/> <div id="blogNoLanding_2" class="fontSizeChange marginbot20px margintop20px"> <input type="hidden" id="blogEntryId_2" value="227709" /> <div class="clearfix botbordergrey padbot2px"> <div class="fleft bold"> <span class="marginright5px bold"> July 02, 2015 </span> <span class="marginright5px">|</span> <span class="bold">By: </span> <span class="bold">Luke De</span> </div> <div class="fright padright5px"> </div> <div class="fright hide hideForPrint"> <ul id="topicPgRightPanelLnks" class="topicDetailsRight"> <li><a href="#" onClick="return false;"><img src="/scitable/natedimages/email.gif" alt="Email" /></a><a href="#" onClick="" class="inlineLinks">Email</a></li> <li><a name="shareLink" href="#" rel="nofollow" onclick="return false;"><img src="/scitable/natedimages/share.gif" alt="Share" /></a><a id="" name="shareLinkTRAnc" href="#" rel="nofollow" onclick="" class="inlineLinks">Share</a></li> </ul> </div> </div> <div class="fright padtop15px hideForPrint"> <a class="padright10px" href="javascript:resizeFontScitable('fontSize11')"><span id="sizeNo1" class="px11 mousePointerHand lh22">Aa</span></a> <a class="padright10px" href="javascript:resizeFontScitable('fontSize15')"><span id="sizeNo2" class="px15 mousePointerHand lh22">Aa</span></a> <a class="padright10px" href="javascript:resizeFontScitable('fontSize20')"><span id="sizeNo3" class="mousePointerHand lh22 px20">Aa</span></a> </div> <div class="clear"></div> <div id="blogParas_2" class="padtop5px botbordergrey padbot4px clearfix margintopn26px" name="blogParas"> <a id="showBlogPost" name="showCmntBlogPost" href="http://www.nature.com/scitable/blog/why-science-matters/herbal_supplements_myths_smoked" class="inlineLinks px15"> Herbal Supplements: Myths Smoked </a> <div class="articleContent"> <div class="clear"></div> <div class="contentSection"> <div class="sectionParas"> <div class="para toWrapLongWord"> <p><span id="docs-internal-guid-3947c90e-4f57-37f2-e588-c30be8556fad"></span></p><p dir="ltr" style="line-height:1.2;margin-top:0pt;margin-bottom:17pt;"> Edited by Allie Logerfo (Georgetown University)<span style="line-height: 1.2;"> </span></p><p dir="ltr" style="line-height:1.2;margin-top:0pt;margin-bottom:17pt;"> <span style="font-family: Arial; font-size: 12px; white-space: pre-wrap; background-color: transparent; line-height: 1.2;">Herbal supplements are really popular.

Traumatic experiences such as rape, abuse, or shell shock result in what is called “aversive learning.” This aversive learning can result in cue or context based expression of fear. This means that items and/or sounds associated with the event (cues) or similar situations (contexts) can trigger the expression of fear. It can be debilitating, forcing people to experience the terror of an already horrible incident over and over again. This is one of the key aspects of post-traumatic stress disorder (<a href="http://www.nlm.nih.gov/medlineplus/posttraumaticstressdisorder.html" mce_href="http://www.nlm.nih.gov/medlineplus/posttraumaticstressdisorder.html" nated_pk="http://www.nlm.nih.gov/medlineplus/posttraumaticstressdisorder.html">PTSD</a>).

Well, shame on you for judging it. It’s a great article that describes a pretty powerful experiment.</span></p><br/><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 15px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">Before I can get into the heart of the article and the research findings, I need to explain two things: the process of experiencing a traumatic memory and the technique of optogenetics. </span></p><br/><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 15px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">The process of experiencing a traumatic memory involves two basic parts. Let’s use the example of a mugging. You first have to gain the information; that is termed acquisition. Seeing a masked man, experiencing fear, and then storing the experience and the paired emotion of fear in your brain is acquisition. The second part, expression, might involve you seeing a completely different masked man and then stopping in your tracks because of that fear. </span></p><br/><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><a href="https://www.youtube.com/watch?v=I64X7vHSHOE" style="text-decoration:none;"><span style="font-size: 15px; font-family: Arial; color: rgb(17, 85, 204); text-decoration: underline; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">Optogenetics</span></a><span style="font-size: 15px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;"> has been around for a little while now, but its usage is permeating more and more of neuroscience. This technique allows a scientist to put a light sensitive switch in a specific subset of neurons. </span><a href="https://www.youtube.com/watch?v=I64X7vHSHOE" style="text-decoration:none;"><span style="font-size: 15px; font-family: Arial; color: rgb(17, 85, 204); text-decoration: underline; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">By shining light on these specific neurons, scientists can stimulate the neuron or shut it down.</span></a><span style="font-size: 15px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;"> It is a step forward in solving one of the toughest problems in neuroscience: resolution. Before optogenetics, shutting down neurons involved using direct injections or lesioning parts of the brain. Neither of these are terribly accurate and affect neurons in the magnitude of thousands - a large section of neurons is damaged and the role of specific neurons cannot be established. Metaphorically, this would be like knocking out a school, seeing that graffiti in an area decreased and then concluding that schools are responsible for graffiti, when in reality, only a couple of kids are responsible for the graffiti. </span></p><br/><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 15px; font-family: Arial; font-weight: bold; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">The Experiment</span></p><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 15px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">This experiment attempts to identify a specific connection between fear/anxiety (Basolateral amygdala, BLA) and memory (hippocampal formation) through a brain region called the entorhinal cortex (EC). Specifically, the authors, Sparta and Smithius, inhibit the BLA-EC pathway to look at its role in both the acquisition and the expression of contextual fear.</span></p><br/><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 15px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">They start by virally “installing” the optogenetic channels into the BLA. This will allow them to control neurons. The two channels they installed, halorhodopsin and channelrhodopsin-2, were attached to a yellow fluorescent protein (YFP). Halorhodopsin allowed the scientists to shut the neurons down and <div class="imageSet Right marginleft10px"><div><img src="/scitable/content/ne0000/ne0000/ne0000/ne0000/132100559/2_1.jpg" mce_src="nated/../content/ne0000/ne0000/ne0000/ne0000/132100559/2_1.jpg" isthumbselected="false" thumbsrc="content/ne0000/ne0000/ne0000/ne0000/132100559/2_1.jpg" orgwidth="1728" orgheight="2592" paraelementcaption="Brain||#|$||Gate" paraelementlegends="http://upload.wikimedia.org/wikipedia/commons/f/fd/BrainGate.jpg" paraelementcopyright="Some||#|$||rights||#|$||reserved." imageinsertyr="2015" legalowner="Public||#|$||Domain" termsofuse="This||#|$||material||#|$||is||#|$||either||#|$||public||#|$||domain||#|$||or||#|$||Nature||#|$||Education||#|$||has||#|$||received||#|$||permission||#|$||from||#|$||the||#|$||owner||#|$||to||#|$||make||#|$||it||#|$||available||#|$||to||#|$||all||#|$||users||#|$||without||#|$||restrictions.||#|$||You||#|$||may||#|$||reuse||#|$||this||#|$||material,||#|$||with||#|$||modifications,||#|$||in||#|$||print,||#|$||electronic||#|$||or||#|$||any||#|$||other||#|$||form,||#|$||for||#|$||commercial||#|$||or||#|$||non-commercial||#|$||purposes." copyrightflag="N" licensetypepk="3" displaycopysymbol="Y" displaylegalowner="Y" displayimginsertyr="Y" displaytermsofuse="Y" displaycopydesc="Y" height="502" width="335" align="right" imgtype="FIG"></div></div>channelrhodopsin-2 allowed them to activate the neurons.

On Day 1, two groups of mice were placed in a room and then shocked. The first group had the BLA-EC pathway inhibited, and the second had the pathway activated. The mice were placed in the room for a short amount of time on Day 2 and then again on Day 3, which was a week later. On Day 2, scientists looked to see if the mice froze when placed in the room without being shocked. Freezing indicated that the mice remembered the context, the room, and associated it with fear. They did the same thing on Day 3.</span></p><br/><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 15px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">Mice with inactive BLA-EC pathways on Day 1 did not freeze as much as mice with active BLA-EC pathways. This indicated that the non-freezing mice, with inhibited BLA-EC pathways, weren’t associating the room with fear even though they had been shocked.</span></p><br/><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 15px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">I am glad that Sparta and Smithius went a step further. They repeated the experiment but only inhibited the BLA-EC pathway in one of two groups when the mice were RE-EXPOSED to the room on Day 2. Shutting down the BLA-EC at this time would mean that the BLA-EC was removed during the expression of contextual fear and not acquisition of it. To clarify, the BLA-EC was not shut down on Day 1, as it was in the previous experiment.</span></p><br/><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 15px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">Both groups of mice froze equally when re-exposed to the room. That means that even mice with inactive BLA-EC froze, which indicates they were experiencing fear to the same degree as mice with the active BLA-EC.</span></p><br/><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 15px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">Let’s summarize everything here. If the BLA-EC pathway was blocked when mice were learning to associate the room with shocks (Day 1), then the mice did not express fear when re-exposed to the room (Day 2 and 3). If the BLA-EC pathway was unblocked when the mice were learning to associate the room with shocks, then the mice did express fear when re-exposed to the room. When the BLA-EC pathway was unblocked during learning, but blocked during re-exposure the mice did express fear.</span></p><br/><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 15px; font-family: Arial; font-weight: bold; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">Discussion</span></p><br/><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 15px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">Sparta and Smithius demonstrated in their experiment that the hippocampus and the BLA communicate while a subject is learning about or experiencing painful stimuli. This means that fear and visual memory are linked during the storage process. I’m interested to know if the mice with the blocked BLA-EC pathway remembered the room. It is possible that they did not freeze simply because they did not remember the room?</span></p><br/><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 15px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">As of right now, I haven’t been able to find any optogenetic studies done on humans. I think the FDA would currently frown on injecting viruses into a person’s head and attaching flashlights that shine into the brain. But this type of technology, in which we voluntarily manipulate very specific neurons, is coming.</span></p><br/><p dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size: 15px; font-family: Arial; vertical-align: baseline; white-space: pre-wrap; background-color: transparent;">PTSD isn’t the only disease involving memory that could benefit from this technology and additional research using optogenentics. Aspects of addiction also involve very powerful learning. Could there be a soldier in whom we could inhibit PTSD? Could there be criminals who could erase memories of their crimes? I have no clue, but certain things are for sure: Our understanding of the brain is changing with new technologies, and our evolved understanding is going to force us to reconsider how we deal with human behavior.</span></p><br/><p dir="ltr" style="margin-top: 0pt; margin-bottom: 0pt;"><font face="Arial"><span style="font-size: 15px; line-height: 20.7000007629395px; white-space: pre-wrap;"><b>Footnotes</b></span></font></p><hr id="null"> <p class="normal" style="line-height:normal"><span style="font-size: 11pt; line-height: 115%; font-family: Arial; color: windowtext;">[1]</span><span style="font-size:10.0pt"> Logerfo can be contacted at </span><a href="mailto:aclogerfo02@gmail.com"><span style="font-size:10.0pt;color:#1155CC">aclogerfo02@gmail.com</span></a><span style="font-size:10.0pt">, if you need help with science writing.</span><o:p></o:p></p> <p class="normal" style="line-height:normal"><span style="font-size: 11pt; line-height: 115%; font-family: Arial; color: windowtext;">[2]</span><span style="font-size:10.0pt"> The other reason is that one of my 12th graders presented this article in Journal Club, and I was confused by it.
