Abstract

A population of neurons in the principal somatosensory nucleus of human thalamus (ventralis caudalis, Vc) had a significant tonic, graded response to cool stimuli and also responded to innocuous mechanical stimuli (mechanical- cool neurons). These neurons were clustered at the dorsal aspect of medial Vc. Stimulation at the sites where these neurons were recorded evoked tingling sensations in the part of the body including or adjacent to the receptive field of these neurons. These neurons may contribute to the mechanism that mediates the perception of cold in man.
