Visual information processing in patients with schizophrenia: evidence for the impairment of central mechanisms.

abstract：:The periaqueductal gray (PAG) is involved in motor activities, such as movements of the neck, back and hind limbs, cardiovascular regulation, micturition, vocalization, and mating behavior, as well as in nociception control. To accomplish these functions the PAG uses information from other parts of the limbic system, ...
