Exploration of the brain from its lateral aspect
Tapetum and tail of caudate nucleus
A window is now cut through the external sagittal stratum to expose the tapetum, a band of fibers from the corpus callosum which passes downward into the temporal lobe. This sheet of fibers lies immediately adjacent to the lateral ventricle. In places (14) it has been removed entirely to reveal the ependymal lining of the ventricle which appears dark in the view. The tail of the caudate nucleus (12) is exposed through much of its course into the temporal lobe.
