H₂O₂ suppresses K⁺-induced population bursting in the CA1 neuronal population of the hippocampus. A: representative trace of the integrated activity from the CA1 neuronal population (∫ CA1) during control and in the presence of 2.2 mM H₂O₂. B–D: the effects of H₂O₂ on burst frequency (B), irregularity score of f_inst (C), and integrated burst area (D) were quantified by comparing 120-s bins during control (CON) to bins ending at 180, 300, and 600 s (black bars) during the 600-s exposure to H₂O₂. n = 6. **P < 0.01, ***P < 0.001.
