The use of automated system for EEG analysis and feedback cerebral stimulation to stop epileptiform activity in WAG/Rij rats.

Original software program is described, which revealed EEG activity characteristic of the onset of epileptic seizure and turned on electrical stimulation of the nucleus basalis of Meynert in WAG/Rij rats with congenital absence epilepsy. The program reliably detected the onset of seizure and automatically stopped it with a high-frequency train of electrical impulses (100-150 Hz). Thus, a feedback system of deep brain stimulation has been developed to stop early manifestations of absence epileptiform seizures.

Electric stimulation of the tuberomamillary nucleus affects epileptic activity and sleep-wake cycle in a genetic absence epilepsy model.

Deep brain stimulation (DBS) is a promising approach for epilepsy treatment, but the optimal targets and parameters of stimulation are yet to be investigated. Tuberomamillary nucleus (TMN) is involved in EEG desynchronization-one of the proposed mechanisms for DBS action. We studied whether TMN stimulation could interfere with epileptic spike-wave discharges (SWDs) in WAG/Rij rats with inherited absence epilepsy and whether such stimulation would affect sleep-wake cycle.
