Publisher Summary Considerable evidence suggests that the cell dense region surrounding
the midbrain aqueduct, the midbrain periaqueductal gray region (PAG), is a crucial neural …

Previous reports indicate that the midbrain periaqueductal gray and the central nucleus of
the amygdala are interconnected but the organization of these projections has not been …

Chemical stimulation of the midbrain periaqueductal gray matter (PAG) in conscious animals
produces opposite responses (viz., defensive behavior and pressor responses from the …

Neurons in the periaqueductal gray (PAG) integrate negative emotions with the autonomic,
