abstract：:1. GABAergic mechanisms in the midbrain periaqueductal gray (PAG) have been proposed to control the activity of descending antinociceptive systems and defensive behavior. Here, the effect of neuronal disinhibition by gamma-aminobutyric acid (GABAA) receptor blockade at midbrain sites on spinal neuronal responses to no...
