Researchers identify 'social cells' in the brain linked to social behavior

A research team led by Professor TAKUMI Toru of Kobe University's Graduate School of Medicine (also a Senior Visiting Scientist at RIKEN Center for Biosystems Dynamics Research) have identified 'social cells' in the brain that are related to social behavior. The cells were identified via Ca imaging conducted using a microendoscope .
