Recording small sharp spikes with depth electroencephalography.
Two patients with intractable seizures and focal temporal sharp waves also had small sharp spikes as incidental findings in their scalp electroencephalograms. Depth electroencephalography verified the intracerebral origin of the small sharp spikes and differentiated them from the more significant epileptiform abnormalities.
