<unk>  refers to abnormal neuronal discharges between epileptic seizures. This abnormal activity can originate from one or more cranial lobes, often travels from one lobe to another, and<unk> feres with normal activity from the affected lobe. Patients with severe,<unk> actable forms of epilepsy can experience unremitting abnormal brain activity due to<unk> . This phenomenon has been confirmed through telemetry by electrocorticography in which electrode grids are positioned sub-durally and augmented by<unk> a-cranial depth electrodes. The EEG tracings from these are correlated with external video recordings of physical responses to epileptic seizures to help determine type of seizure and origin of onset.
