Depolarization-induced suppression of inhibition (DSI) is a process whereby brief approximately 1-s depolarization to the postsynaptic membrane of hippocampal CA1 pyramidal cells results in a transient suppression of GABA(A)ergic synaptic transmission. DSI is triggered by a postsynaptic rise in [Ca(2+)](in)
