b2726 Self and the Phenomenon of Life: A Biologist Examines Life from Molecules to Humanity “9x6”Fig. 10.1. Simplified drawing of a human brain in coronal section (vertical
cross-section) showing the location of the hippocampus and entorhinal cortex (shaded
areas) in both hemispheres. Note that the hippocampus is the in-rolling portion of the
medial side of temporal lobe. Other brain areas are labeled for landmark purposes.
Fig. 10.2. Cutout view from the right half of Fig. 10.1 showing details of the hippo-
campus and related structures. The “hippocampus proper” or simply “hippocampus”
comprises the CA3 and CA1 structures, whereas the “hippocampal formation” includes,
in addition, the dentate gyrus and subiculum. Some authors consider the entorhinal
cortex as part of the hippocampal formation, since it serves as the gateway to the hippo-
campus.[See Note 11: Kandel et al. courtesy McGraw-Hill.]
