Fig. 9 Anterior portion of section 143, as shown in figure 6. Anteriorly is 
shown the head of the caudate nucleus (cap.n.caud.) without any definite cover- 
ing of cerebral cortex. In the temporal lobe (lob.temp.) is the nucleus amygdalae 
(n.amyg.), subdivided by crossing bundles of medullated fibers. Ventral to the 
corpus callosum (corp.call.) is a more lightly staining band of fibers, crossing the 
midline and constituting the psalterium (psalt.). The lateral regions of this 
band contain fibers which, not crossing, continue as the fornix fibers. X 2.

cing., gyrus cinguli; lam.quad., quadrigeminal plate; thal. op., optic thalamus.
