The hippocampal formation is implicated in several important psychiatric and neurological problems. The hippocampus and amygdala are often the site of epileptic foci which can lead to problems in learning and memory, emotion, anxiety, and other problems. This kind of epilepsy is variously known as temporal lobe epilepsy, complex partial seizures, or limbic epilepsy. The hippocampus, with associated limbic areas, has been linked both to affective disorders and to psychoses including schizophrenia. This chapter will consider the cellular organization of the hippocampus and then outline aspects of the emergent properties of neuronal networks in the hippocampus and speculative role in psychiatric disorders. Cellular and network mechanisms of focal epilepsy, and learning impairments associated with limbic epilepsy will be reviewed.

A central element in this chapter is the idea that the functional organization of neuronal networks plays a key role in the normal and pathological operation of the brain. For brevity (and for the author's convenience) the examples concern the hippocampus, but similar principles apply in the neocortex and other parts of the brain.
