Role of noradrenergic arousal for fear extinction processes in rodents and humans.

Publication Type: Academic Journal

Source(s): Neurobiology of learning and memory [Neurobiol Learn Mem] 2022 Oct; Vol. 194, pp. 107660. Date of Electronic Publication: 2022 Jul 21.

Abstract: Fear extinction is a learning mechanism that is pivotal for the inhibition of fear responses towards cues or contexts that no longer predict the occurrence of a threat. Failure of fear extinction leads to fear expression under safe conditions and is re...
