Abstract

Single-unit recordings and optogenetic manipulations in mice undergoing auditory fear conditioning show that fear expression is related to the phasic inhibition of prefrontal cortex (PFC) parvalbumin interneurons; inhibition disinhibits PFC projection neurons and synchronizes their firing, leading to fear expression.
