"...connections with the external division of the medial dorsal nucleus of the thalamus and the superior colliculus (Leonard, '69) and because eye and eyelid movement may be caused by electrostimulation in this field in the rat as in field 8 of gyrencephalic mammals (Hall and Lindholm, '74)."
" The cell pattern of field 8 differs from that of 6 in that the condensation of superficial pyra- mids of layer I1 is more conspicuous whereas the granular layer IV is very at- tenuated. The pattern of radial fibers is more dense as is the tangential stratum in layer I. A dense tangential stratum in layer VI merges with the cingulate bundle in the depths of field 8. "
