The tagging of the receptors at these locations with gold enabled fast and easy end pointing and stacking of images.</p> <p>They then zoomed in on these regions of interest at high resolution, delivering images that they could use to measure the critical dimensions of the receptors in which they were interested.</p> <p>Being able to compare different samples, frozen at specific time points in a fast and time efficient manner, enabled a deeper understanding of synaptic function.
