Functional Properties of Neurones in the Primary Somatosensory Cortex

The primary somatosensory cortex (SI) receives its main input from the thalamic ventrobasal complex. In the monkey the projection to area 3b is heavy and made up of singularly coarse fibres, whereas the fibres to areas 1 and 2 are much fewer in number and finer in calibre. It is possible that the fibres to areas 1 and 2 are branches of the coarser fibres passing to area 3b (Jones and Powell 1970b). The most anterior part of SI, area 3a, also receives a projection from the ventrobasal complex from the subnucleus ventralis posterolaterals, pars oralis (VPLo) (see Jones and Powell 1973).
