Fig. 11 Anterior portion of section 153, as shown in figure 6. Covering the 
caudate nucleus (n.caud.) is the typical frontal cortex, but covering the nucleus 
lentiformis (n.lent.) are two differently-appearing surface coverings. The re- 
mains of the parolfactory cortex are shown by the presence of a superficial fiber 
layer, raised internally at intervals into little elevations. The region marked 
olf.cort., is taken to be region where the olfactory cortex existed formerly. Ven- 
tral to the corpus callosum (corp.call.) is a more lightly staining band which con- 
tains fibers (1) of the psalterium (fibers crossing the midline), (2) of the fornix (for.) 
which are laterally placed, and (3) possibly of Zuckerkandl’s bundle. X 2. 
III, third ventricle; caps.int., internal capsule; c.p., posterior commissure ; 
gy.cing., gyrus cinguli; lob.temp., temporal lobe; massa interm., massa intermedia ; 
thal.op., optic thalamus.
