The nucleus lateralis and medialis thalami allow the posterior end of the nucleus anterior to extend between them dorsally; ventrally they flow together. Here begins the region of the nucleus ventralis. The more posterior portion of the ansa lentiformis streams in here, and other fibers from the corpus striatum go to the gray Nucl. caud.

The lamina meduUaris interna thalami has become much richer in fibers, and between the latticed layer and the lateral nucleus there develop the tracts of the lamina medullaris externa thalami. The stratum zonale is very perceptibly diminished, and the ttenia is to be seen more clearly. The lenticular nucleus, the claustrum, the capsulse, and the cortex of the insula, with the exception of somewhat altered forms, present nothing that differs essentially from the sections previously shown. In the white medullary substance the long asso- ciation-tracts may still be sought for in the same situations Avhere they lay in the section shown in Fig. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original wo
