摘要：

Discharges were recorded from spinal dorsal horn neurons in response to noxious skin heating (e.g. 50°C). Repetitive electrical stimulation of the mesencephalic periaqueductal gray (PAG) inhibited these nociceptive discharges. In each of 9 experiments systemic administration of naloxone (1-3 mg/kg) did not affect this descending inhibition, arguing against involvement of endogenous opiates. © 1979.
