The magnetic fields associated with penicillin-induced focal epilepsy were measured in laboratory rats. Interictal magnetic spikes were similar to those previously observed in humans with focal seizure disorders. The magnetic fields of the seizure itself displayed both slow and fast phenomena, reversing in direction on opposite sides of the head.
