The brain waves recorded from electrodes deep in her brain demonstrated transient episodes of spiking in a midline limbic structure called the septum and in the right hippocampus, deep in the temporal lobe. Paul MacLean and others since have shown that electrical stimulation of these and related brain regions could produce pleasure and grooming reactions in cats and prolonged penile erections in squirrel monkeys. Many years later, | spoke about Donna with the Harvard professor of neurology, Norman Geschwind. He took me to his twice a week epilepsy clinic. In an effort to demonstrate what is now known as the Geschwind Syndromes of between seizure, inter-ictal personality changes in patients with temporal lobe epilepsy, he stood in front of the patients’ waiting room.
