Epilepsy is a disorder of the central nervous system in which a group of neurons discharge abnormally and spontaneously. The disorder is behaviorally manifested in many ways depending on which part of the brain is affected. Seizures may be associated with motor functions and be accompanied by grand mal convulsions (tonic-clonic), muscle twitching (myoclonic), or a loss of motor tonus (akinetic). Other seizures may be associated with sensory changes and/ or changes in emotionality (petit mal and psychomotor). However, all epileptic seizure disorders have the common feature that they are associated with an abnormal neuronal discharge in specific foci of the brain. Hence, investigations of biofeedback applications to epilepsy have utilized feedback of the brain’s electrical activity in attempts to teach the individual to alter this activity and thus prevent the occurrence of seizures.
