title: Evoked cerebral responses to noxious thermal stimuli in humans.
abstract: Brief pulses of Laser emitted radiant heat were used to induce cutaneous painful sensations in human volunteers. Accurate timing of the stimuli permitted recording of scalp averaged evoked potentials. A late negative-positive component of the EP which correlated in amplitude with the subjective sensation was observed in four subjects. The latency of this component (130-160 msec) correlated with stimulus intensity.
