Neural Map Details the Primate Connectome

The ability to comprehensively map the architecture of connections between neurons in primate brains has long proven elusive for scientists. But a new study, conducted in Japan with contributing neuroscientists from Cold Spring Harbor Laboratory (CSHL), has resulted in a 3D reconstruction of a marmoset brain, as well as information about neuronal connectivity across the entire brain, that offers an unprecedented level of detail.

The study has introduced new methodology, combining experimental and computational approaches, that helps account for significant variation between individual brains. It allows for synthesizing unique brain connectivity maps into a single reference brain. The resulting data set for the marmoset brain is an ideal launching-off point for further studies, and scientists believe it may offer insights into human neural connectivity.
