Abstract: &NA; Exposure of rats to an environment with low O2 levels evokes a panic‐like escape behavior and recruits the dorsal periaqueductal gray (dPAG), which is considered to be a key region in the pathophysiology of… read more here.

DOI: 10.1111/ejn.15633
Abstract: The dorsal periaqueductal grey (PAG) is an important site for integrating predatory threats. However, it remains unclear whether predator‐related activation in PAG primarily reflects threat itself and thus can distinguish between various degrees of threat,… read more here.

D2-like receptor activation by intranasal dopamine attenuates fear responses induced by electrical stimulation of the dorsal periaqueductal grey matter, but fails to reduce aversion to pit vipers and T-maze performance

Abstract: Background: Panic-like reactions elicited by electrical stimulation of the dorsal periaqueductal grey matter (ES-dPAG) seem to be regulated by dopamine (DA). We showed that DA applied intranasally (IN) increased escape-behaviour thresholds induced by ES-dPAG of… read more here.

DOI: 10.7554/elife.64934
Abstract: Animals must balance needs to approach threats for risk assessment and to avoid danger. The dorsal periaqueductal gray (dPAG) controls defensive behaviors, but it is unknown how it represents states associated with threat approach and… read more here.
