A. Suppression of epileptiform activity by 5-minutes optical stimulation. 20 Hz optical stimulation, indicated by blue bar, could the reduction of burst frequency induced by 100 ⍰M 4-AP solution. B. Optical stimulation had no effect on the spontaneous activity induce by 4-AP plus 100 ⍰M picrotoxin (PCTX). C. The summary of spontaneous activity frequency before, during, and after stimulation. There was no significant change caused by optical stimulation when the GABAA receptors were blocked by picrotoxin solution.
