The Norwegian author Tryggve Andersen (1867-1920) had epilepsy, but was not aware of the diagnosis until late in life. In one novel, Towards Night (Mot Kvaeld), published in 1900, he described in detail nocturnal attacks with formed visual hallucinations as the initial event, seeing always the same face. He was familiar with the works of Ernst Hoffmann and probably also with those of Fiodor Dostoyevsky, but deduction of the literary influence leaves a precise description corresponding to an epileptogenic focus in the right posterotemporal region. Knowledge of his work may elucidate the subjective experience of initial epileptic manifestations, uncontaminated by previous knowledge of what can be expected in epilepsy. The descriptions provided by Andersen's writings are compared with more formal contemporary definitions of seizure events.

The correlation between clinical epilepsy and pathologic changes in the hippocampus was recognized in the early 1800s. However, the study of hippocampal pathology remained an anatomically descriptive discipline until the mid 1970s. In 1976, exploration of the electrical characteristics of the epileptic hippocampus and temporal neocortex began with the application of in vitro electrophysiologic techniques to human brain slices. Subsequently, recognition of the importance of neurotransmitters in epilepsy prompted ligand binding studies of receptor distributions in the epileptic brain. Recent refinements of DNA isolation and immunocytochemical techniques have led to the explosive development of antibodies to receptors, neurotransmitters, enzymes, and neurotransmitter transport systems. Since the 1980s, several alterations in epileptic hippocampus have been discovered with use of these pharmacologic and biochemical tools. The combination of anatomic, electrophysiologic, and biochemical experimental approaches has led to valuable insights into epilepsy-associated changes in temporal lobe tissue and has increased our understanding of the pathophysiology of temporal lobe epilepsy. Most of the summarized data in this review were derived from tissue excised from patients with medically intractable temporal lobe epilepsy or from postmortem brain. Although no attempt was made to cover the vast literature on animal models of epilepsy, some animal studies are discussed to illustrate current hypotheses that aid in the interpretation of the human findings.
