Research Abstract

Somesthetic information arising from orofacial structures is processed in the lateral part of the postcentral somatosensory cortex and itsneighboring association cortex. There, nearby pairs of neurons responded to a natural stimulus, or were activated during successive tongue movements, with varying degrees of temporal correlation. The temporal diversity of neuronal activity within a small region might help the brain to monitor the time course of sustained tactile stimulation, or successive orofacial movements.
