pocampi to the opposite side (Fig. 36). They terminate in the 

 dentate fascia and hippocampal gyrus, including the uncus. The 

 associative group of fibers in the jornix has the same origin as the 

 commissural group. It enters cms fornicis and continues through 

 the body of the fornix (corpus fornicis) into the columna, where

it divides into two unequal bundles: The smaller is the stria 

 medullaris thalami (pineal stria) (Fig. 40), which bends backward 

 and runs along the supero-medial border of the thalamus to the 

 nucleus habenulae ; in part it decussates in the commissura habenu- 

 larum. By the fasciculus retroflexus of Meynert, it is connected 

 with the inter-peduncular ganglion of the mid-brain. The larger 

 bundle continues as columna fornicis (Fig. 74). As already
