@hopeful33250 this procedure was done in 1976. It was done after I saw a neurologst at the Children's Hospital of Philadephia in 1967. A neurosurgeon who worked with a doctor specializing in epilepsy at Graduate Hosp. there did the procedure. I have since moved I live in Baltimore and see and epileptologist. She has me on a regimen of lamogrigine, Depakote and zonisamide. That is working better than surgery. I now have one seizure a month and they are all nocturnal.
