Lab 11 - The Limbic System
Cortical Areas of the Limbic System
Begin by identifying the cortical areas of the limbic system that are visible on the hemisected brain. On the medial surface, follow the subcallosal gyrus (which is inferior to the rostrum of the corpus callosum) as it continues into the cingulate gyrus. Follow the cingulate gyrus posteriorly back along the splenium of the corpus callosum as it turns into the isthmus. On the inferior surface of the brain you can follow the isthmus into the parahippocampal gyrus. The hippocampal formation cannot be seen in an uncut brain as it lies superior to the parahippocampal gyrus. The hippocampal formation forms the floor of the temporal horn of the lateral ventricle.
