The epilepsy is often caused by epileptogenic brain tumors. [3] Brain imaging studies support activation of the anterior insula in ecstatic seizures. [4] [2] Additionally, several instances of reproducible ecstatic-like seizures have been induced during presurgical evaluation with electrical brain stimulation to the dorsal anterior insula.
Kindling is a commonly used model for the development of seizures and epilepsy in which the duration and behavioral involvement of induced seizures increases after seizures are induced repeatedly. [1] Kindling is also referred as an animal visual model of epilepsy that can be produced by focal electrical stimulation in the brain.
