✦ Synopsis

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.

The relationships between different parameters of the evoked cerebral response to noxious thermal stimulation, stimulus intensity, and subjective pain were investigated in seven normal human volunteers. The evoked response was characterized by late events: a small negative peak at 164--180 ms, follo

## Abstract This study examined the latency relationship between mechanically and electrically elicited sensory nerve action potentials (SNAPs) and the somatosensory‐evoked potentials (SEPs) they produce. Brief air‐puff and electrical stimuli were applied to the tip of the index finger in separate

Reponses evoked by warming the glabrous palmar skin were recorded maximally from a contralateral parietal scalp site that approximated the hand projection area of sensorimotor cortex. A smaller and later occurring response was also seen at the corresponding ipsilateral site. The temperature to which
