The hippocampus is a small, curved formation in the brain that plays an important role in the limbic system. The hippocampus is involved in the formation of new memories and is also associated with learning and emotions. Because the brain is lateralized and symmetrical, you actually have two hippocampi.
In Alzheimer's disease, the hippocampus is one of the first regions of the brain to suffer damage; memory loss and disorientation are included among the early symptoms.Damage to the hippocampus can also result from oxygen starvation (hypoxia), encephalitis, or medial temporal lobe epilepsy.n adult humans the volume of the hippocampus on each side of the brain is about 3.0 to 3.5 cm 3 as compared to 320 to 420 cm 3 for the volume of the neocortex. There is also a general relationship between the size of the hippocampus and spatial memory.
