Touching textured surfaces: cells in somatosensory cortex respond both to finger movement and to surface features

I Darian-Smith, M Sugitani, J Heywood, K Karita, and A Goodwin

Single neurons in Brodmann's areas 3b and 1 of the macaque postcentral gyrus discharge when the monkey rubs the contralateral finger pads across a textured surface. Both the finger movement and the spatial pattern of the surface determine this discharge in each cell. The spatial features of the surface are represented unambiguously only in the responses of populations of these neurons, and not in the responses of the constitutent cells.
