Abstract：
:The principal finding in this study is that the callosal projection to the occipital cortex in rats and mice follows a complex and highly reproducible pattern which has not previously been described in detail. In some regions, the callosal projection is associated with well defined cytoarchitectonic boundaries such as the border between areas 17 and 18a. However, extrastriate cortex lateral to area 17 receives callosal inputs which are not related to previously defined cytoarchitectonic boundaries. Following intraocular injections of [3H]fucose, transneuronal label occupies area 17 and mainly the posterior part of area 18a. A region in posterolateral area 18a which is 'subdivided' into callosal and sparsely callosal regions appears to receive an input from the lateral geniculate nucleus, based on transneuronal autoradiography. Comparison of the distribution of callosal axons and transneuronal label suggests that regions of murid cortex similar to areas 18, 19 and lateral suprasylvian cortex in cats may be located posteriorly in area 18a.
