Neurotransmitters in the Dorsal Periaqueductal Grey and Animal Models of Panic Anxiety

  • Chapter
New Concepts in Anxiety

Abstract

The dorsal periaqueductal grey (DPAG) of the midbrain belongs to a longitudinally organized neural system, responsible for the behavioural and neurovegetative expression of defence reactions, like fight or flight, and for the elaboration of aversive emotional/motivational states. In addition to the DPAG, the medial hypothalamus as well as the central and dorsomedial amygdala constitute the so-called ‘brain aversive system’ (for reviews see Graeff, 1987, 1988, 1990).
