The periaqueductal gray
WebbProjections from the lateral parabrachial nucleus to the lateral and ventral lateral periaqueductal gray subregions mediate the itching sensation. Lateral and ventral lateral … WebbThe periaqueductal gray ( PAG, also known as the central gray) is a brain region that plays a critical role in autonomic function, motivated behavior and behavioural responses to threatening stimuli. [1] [2] PAG is also the primary control center for descending pain modulation. It has enkephalin -producing cells that suppress pain.

WebbThese results demonstrate that depression-like behavior is associated with remarkable reduction in glutamatergic, but not GABAergic, transmission in the vlPAG. These neuroplastic changes and maladaptive behavior are attributed to GRdependent mechanisms.

Furthermore, the ACC projection fibers were also found in the ipsilateral anterior and posterior thalamic nuclear groups. Webb6 mars 2016 · The periaqueductal gray (PAG) plays a pivotal role in pain modulation. We attempted to examine the relation between injury of the PAG and central pain in patients …
WebbDeep brain stimulation of the dorsolateral periaqueductal grey (dlPAG) and the ventromedial hypothalamus (VMH) in rats has been shown to induce escape behaviour, which mimics a panic attack in humans. We used this animal model to study the neuronal activation in the deep cerebellar nuclei ...
