Development of neural circuit tracing for mapping the connectome in the common marmoset

The function of the nervous system emerges from complex interactions between networks of neurons composed of multiple neuron types. Understanding how these networks function both in health and disease requires revealing the connectivity between specific neuron types. The goal of our study is to develop a neural circuit tracing method combined with cell-type-specific targeting that makes it possible to map the connectome in the common marmoset brain.
