Abstract

Intracellular potentials were recorded from nociceptive neurons (NCNs) in primary somatosensory cortex area (SI) of cats in response to stimulation of ventral posterior laterla nucleus (VPL). The responses of NCNs evoked by stimulating VPL and SN might be similar or different. Implications of the differences of NCN and NNCN were discussed.

Key words: Primary sensory cortex(SⅠ);Ventrol posterior lateral nucleus(VPL);Nociceptive neuron;Cell membrane constant
