Those proceeding from thecortex of the gyrus fornicatus, constituting the ascending pillarof the fornix (or superior peduncle of optic thalamus). The fornixitself is the projection fasciculus of the cortex passing to theanterior eminence of the optic thalami. The deeper-lying part of the optic thalamus receiving thecorona radiata contains many cells, and constitutes the rednucleus of the tegmentum. This red nucleus is the first inter-node of a tract that originates in the cortex of the cerebrum ina fan-like form, and stretches to the cortex of the cerebellum.The processus a cerebello ad cerebrum is a free segment of thisconnecting tract between the two layers of cortical substance. Beneath the above-mentioned fan is a second more slender fan of the corona radiata, which isapplied to the substance of Soemmerring. Posteriorly the optic thalami are connected with I he

The optic tracts are also connected just as if they were a portion of the coronaradiata with the hrachium of the inferior corpus quadrigeminum. The optic tracts and nerves,therefore, are not peripheric nerves, but the retina, like the olfactory bulb, is, so to speak, anoutlying portion of the cortex cerebri. Fig. 245.
