Details

scope
Mouse cortex (Pyr, PV-Cre, SST-Cre), ex vivo whole-cell patch clamp + computational model of Up states
claim_text
During cortical Up states in mouse, PV interneurons (not SST) are the dominant inhibition stabilizer of recurrent E→E activity, and the Pyr↔PV recurrent inhibitory loop is stronger than the Pyr↔SST loop.
