Abstract: Connections between the midbrain dorsolateral periaqueductal grey (dlPAG) and the pontine A5 region have been shown. The stimulation of both regions evokes similar cardiovascular responses: tachycardia and hypertension. Accordingly, we have studied the interactions between… read more here.

DOI: 10.1111/bph.14982
Abstract: The midbrain periaqueductal grey (PAG) plays a central role in modulating pain through a descending pathway that projects indirectly to the spinal cord via the rostroventral medial medulla (RVM). While opioids are potent analgesics that… 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.76278
Abstract: The pivotal role of the periaqueductal grey (PAG) in fear learning is reinforced by the identification of neurons in male rat ventrolateral PAG (vlPAG) that encode fear memory through signalling the onset and offset of… read more here.
