Abstract:
Electroencephalography (EEG) is the non invasive tool to record the spontaneous electrical activity in the cerebral cortex of the brain. The main aim of study was to identify normal EEG patterns in healthy dogs and the interictal epileptiform discharges (ED) in dogs affected with idiopathic epilepsy (IE). Chemical restraint was achieved by intramuscular injection of xylazine in all dogs and recorded with bipolar montage. Normal dog showed alpha rhythm with frequency ranging between 8-13 Hz. The abnormal EEG changes were observed in six dogs with idiopathic epilepsy were spikes and spikes complexes in 4 dogs (66.67%), and sharp and slow waves in 2 dogs (33.33%). All the 6 dogs had generalized seizures and showed bilateral changes in electroencephalographic study with bipolar montage.
