The somatically evoked activity was recorded of single units in the ventral posterior lateral thalamus (VPL) of awake monkeys while they detected the termination of task-relevant somatic or visual stimuli. Eighteen of 56 somatically responsive VPL neurons are reported that were recorded for enough time for a complete analysis of their responses during both the visual and somatic attention tasks. All neurons were spontaneously active and responded either to innocuous cutaneous (13/18) or deep (5/18) stimuli. Seven neurons (7/18, 38.8%) showed AM of somatosensory responsiveness. Two cells (2/7, 28.6%) showed AM only during the visual task, two others (2/7, 28.6%) only during the somatosensory task, and three cells (3/7, 42.8%) showed AM during both tasks. All five cells showing AM during the somatosensory task had enhanced responses to the task-relevant somatic stimulus. In contrast, the somatosensory responses of all five cells showing AM during the visual task were reduced. It is concluded that selective attention is associated with a modality specific modulation of the somatosensory responses of a sub-population of neurons within the primate VPL nucleus.","author":["Morrow, T.
