Document Summary

The receptive fields of neurons in layer ivc are similar to the magnocellular and parvocellular. Outside layer ivc, new receptive field characteristics, not observed in the retina or lgn, are found. Neurons in layers ivc and ivc receive afferents from a layer of the lgn representing either eye. Monocular neurons from either eye are also clumped together in v1 rather than randomly intermixed and this accounts for ocular dominance columns. Axons leaving layer ivc diverge and innervate more superficial cortical layers. As a result, there is a mixing of inputs from the two eyes (see fig. Most neurons superficial to ivc are binocular and have binocular receptive fields. Most receptive fields in the retina, lgn and layer ivc are circular and give greatest response to a spot of light matched in size to the receptive field center. Outside layer ivc, cells do not follow this pattern.
