Neural mechanisms of individual recognition

Within a close-knit social group, recognizing an individual as a unique identity and associating and retrieving individual-specific information during social interactions are a fundamental ability for living as a member of the group. Although individual recognition has been reported in many different species including rodents, its neural underpinnings remain unclear.

My lab has been developing simplified and precisely controlled individual discrimination paradigms in which subject mice distinguish between individual mice belonging to the same social category. Together with quantitative behavioral measures, we use multiple state-of-art techniques including two-photon calcium imaging, miniscope imaging, and Neuropixels recordings to reveal neural mechanisms of social recognition.
