If an epileptic seizure is focused in a particular sweet spot in the temporal lobe, a person wonยดt have motor seizures, but instead something more subtle. The effect is something like a cognitive seizure, marked by changes of personality, hyperreligiosity (an obsession with religion and feelings of religious certainity), hypergraphia (extensive writing on a subject, usually about religion), the false sense of an external presence, and, often, the hearing voices that are attributed to a god. Some fraction of historyยดs prophets, martyrs, and leaders appear to have had temporal lobe epilepsy.
