[Arrangement and afferent connections of the neurons in the visual cortex differing in the size of the receptive fields].
In the area 17 of the cerebral cortex of guinea pigs cells with small and medial receptive fields (RF) are concentrated at the sites of separate groupings of neurons excited by flashes of diffusion light. There are also cells with large RF here. At such sites of the cortex when specific afferents are electrically stimulated many cells exhibit monosynaptic activation irrespective of their RF size. The main part of the neurons with large RF is situated in the areas of the cortex between the excited grouping and monosynaptical excitation is not inherent in such neurons. Most cells of these areas are not excited by specific afferents.
