	The Hippocampus
		Although the dentate gyrus is commonly included as part of the Hippocampus, it is cytoarchitectonically distinct from the hippocampus proper (the architecture, or structure of the cells is different; Amaral 1978; Bayer, 1985; Amaral and Witter, 1989; Witter, 1989).
		Of course, the hippocampus still held preminance as the structure responsible for conscious learning, an idea was reinforced by the report of a stroke case, in which damage restricted to the CA1 subfield of the hippocampus, resulted in amnesia (Zola-Morgan, Squire, and Amaral, 1986; but see Horel, 1994).
		Lesions upstream of the hippocampus such as the perforant path, the main entorhinal input to the hippocampus (Skelton and McNamara, 1992) and lesions to the medial septum, the other major input to the hippocampus (Hagan et al., 1988) also disrupt acquisition.

	Hippocampus Handout
		The hippocampus (together with anatomically related structures) is essential for a specific kind of memory, here termed declarative memory (similar terms include explicit and relational).
		The first suggestion that the hippocampus is involved in only one kind of memory was developed by Hirsh (1974) on the basis of studies of rodents with hippocampal lesions.
		The cortical structures adjacent to the hippocampus (entorhinal, perirhinal, and parahippocampal cortex) appear to participate with the hippocampus in a common memory function.

		The hippocampus, a brain area critical to forming new memories, is particularly vulnerable to the effects of the gas.
		Three brain structures, the hippocampus, the cerebellum, and the basal ganglia, "seem to be more vulnerable than other parts of the brain," Hopkins explains.
		The hippocampus, the region of the brain responsible for transferring new information to long-term memory, is most vulnerable because it sits deep in the middle of the temporal lobe, at the very end of the blood's circulation route.

		"The hippocampus actually refers to two structures, the right hippocampus and the left hippocampus that are located in the right and left temporal lobes of the brain," explained Thomas P. Beresford, Department of Veterans Affairs physician, and professor of psychiatry at the University of Colorado Health Sciences Center.
		Before this study, researchers had noticed that the volume of the hippocampus seemed to be smaller in people who frequently drank large amounts of alcohol for long periods of time." Beresford is also the corresponding author for the study.
		Since the hippocampus is connected to many other parts of the brain, it is difficult to know all of the things that it does.
