Serial transverse sections of the brain stem

Diencephalon and telencephalon; level of anterior commissure

This section is 6 mm. above the level of the previous view. Relations of the anterior commissure (24) are visible. The frontal stalk of the thalamus (11) can be traced into the anterior limb of the internal capsule. The section passes just below the interventricular foramina (23).
