Exploration of the brain from its basal aspect
Ependymal lining of lateral ventricle; lateral aspect of thalamus
The caudate nucleus has been scraped away from the ependymal lining of the lateral ventricle which covers its upper and medial aspects. This membrane remains intact and the outlines of small uninjected veins may be traced within it. These are tributaries of the terminal vein. Between the position occupied by the caudate nucleus and the internal capsule is a ridge which consists of fibers of the superior occipitofrontal fasciculus. The cavity of the inferior horn of the lateral ventricle is further exposed. The thalamus has been uncovered by scraping away its external medullary lamina.
