Abstract:
All the cortical areas in MSS except for area 7 have reciprocal connections with primary sensory areas of the cerebral cortex (SⅠ, SⅡ) and with some thalamic nuclei which are related with specific sensations (e. g. layer B of lateral geniculate nucleus, medial interlaminar nucleus, medial part of posterior nuclear group).Area 7 lying in the central part of MSS, has close connections with its surrounding areas and is thus indirectly connected with the specific sensory system.Both homotopic and heterotopic callosal connections exist for some cortical areas of cat's MSS. The heterotopic callosal connections of a given cortical area are always corresponding to the areas which have ipsilateral connections with the given area.Most of the labeled cells are found in layer Ⅲ of cerebral cortex and are pyramidal in shape, the rest are in layer Ⅱ, Ⅳ,Ⅴ and Ⅵ. The labeled terminals (and/or preterminals) are distributed to all layers of cortex, predominantly in superficial layers (Ⅰ～Ⅲ).
