ABSTRACT
Seizures and epilepsy are clinical phenomena resulting from hyperexcitability of the neurons of the cerebral hemispheres. They may be defined in both physiological and clinical terms.
Physiologically, epilepsy is the name for occasional sudden, excessive, rapid and local discharges of gray matter. Evidence to date indicates that increased and hypersynchronous neuronal discharges are the essential features involved in the generation of seizures.
