Neural Connectomics Puzzling Overview.

<p><b>(A)</b> An example of 9 connected neurons (circles). Lines signify connections. <b>(B)</b> After the brain is homogenized, the only remaining information is a record of the connections. Connections are shown here as adjacent circles. <b>(C)</b> A connectivity matrix is constructed describing the connections between neurons. Gray signifies a connection. Since connections are correlated with how close neurons are to one another, this connectivity matrix can be treated as the similarity matrix. <b>(D)</b> The neurons are puzzled back together. The formation may be rotated or flipped, as shown here.
