(FRAME-INFO (STRING " MRI Sagittal Composite. \(Scans compliments of Dr. K. Maravilla, Dept. of Radiology, University of Washington\). There are some really nice subtleties here.  The most medial section is at the top left \(Section A, 2.6 mm off the midline\). You can see the  fornix near the splenium of the corpus callosum, the anterior commissure crossing the midline, the fornix as it passes to the mammillary body, and the mammillothalamic tract leaving the mammillary body en route to the anterior nucleus of the thalamus. The cingulum is present though not labelled \(it is labelled in section B\). The next lateral section \(B, 7.8 mm off the midline\) passes through the caudate nucleus. Note again the anterior commissure and a bit of fornix at the splenium. In sections C and D, the hippocampus is visible in the floor of the inferior horn of the lateral ventricle.  Use the anterior commissure in each case as a landmark. The amygdala is present just anterior to the inferior horn of the lateral ventricle. "))
