Throughout this decade Dr. Williamson, as well as Dr. Susan Spencer and others on the team, reported the semiology of multiple partial seizure types based on site of origin and in particular helped define complex partial seizures of frontal, temporal, parietal and occipital origin. Drs. Susan and Dennis Spencer and colleagues also assembled experience with corpus callosotomy and defined both the benefits and risks.
Other epilepsy fellows including Drs. Ami Katz, James Thompson, David Tkeshalashvili, and Evan Fertig (recently worked with Dr. Fuki Hisama to identify a new genetic mutation in a family with autosomal dominant auditory temporal lobe epilepsy) stayed on the faculty temporarily to help the program for a few years before entering private practice.
