Figure 1.

Comparing epileptiform burst discharges in PTZ and control groups which were recorded by the electrocorticogram (A). The latency in all pretreatment groups was significantly more than PTZ group (B). The frequency of burst discharges in pretreatment groups was significantly less than PTZ group (C). The amplitude of burst discharges in Ext 50-PTZ, Ext 100-PTZ and Ext 200-PTZ groups was also significantly lower than PTZ group (D). Finally, the duration significantly increased in pretreatment groups as compared to PTZ group (E). ⁺ p<0.05, ⁺⁺ p<0.01 and ⁺⁺⁺ p <0.001 compared to PTZ group
