Human Synapses (IMAGE) Wellcome Trust Sanger Institute Caption Brain tissue samples were removed from patients undergoing brain surgery (left image). As shown in the middle image, two nerve cells are shown with their long branches which contact one another at synapses and one of them is boxed (for illustration purposes). From the synapses, the proteins were identified and as shown in the right image, each protein can be represented as a point, and the lines show the connections between proteins. This shows how the many proteins in the PSD are connected in a network or roadmap. Many of these proteins are involved in human diseases and these are shown as "stars" in the protein network map.
