The growth factor BDNF and its receptor TrkB are important for inhibitory neuron development and have been implicated in neuropsychiatric disorders. However, the behavioral consequences of impaired BDNF/TrkB signaling are unknown. Using a transgenic mouse line, we show that mice with deletion of BDNF/TrkB signaling from cortical inhibitory neurons exhibit social dominance and decreased inhibition within the prefrontal cortex, a key region regulating social behavior. Reversal of the network imbalance with optogenetic inhibition could rescue the behavior. Our results reveal a previously uncharacterized role of growth factor signaling within cortical interneurons for the development of social cognition.||URI:||https://hdl.handle.net/10356/81153
