Study shows parvalbumin-interneurons in the amygdala influence fear memory encoding

Fear memory encoding, the process responsible for persistent reactions to trauma-associated cues, is influenced by a sparse but potent population of inhibitory cells called parvalbumin-interneurons (PV-INs) in the amygdala, according to a study conducted at the Icahn School of Medicine at Mount Sinai and published online July 14 in the journal Neuron.
