摘要：

Responses of ventrolateral orbital cortex (VLO) neurons to innocuous touch and pressure, and noxious pinch and cold were examined by extracellular recordings. Eight neurons increased their firing rate in a graded fashion to all stimuli applied, 4 units decreased their discharges, and 6 neurons remained unaffected. All responsive units displayed the greatest change in firing rate during noxious cold, and all exhibited whole-body receptive fields. These data further implicate the VLO in nociception.
