Zylla, Xiaomin Zhang, Susanne Reichinnek, Andreas Draguhn, Martin BothA: Increase of amplitudes was significantly stronger after an intermittent carbachol induced gamma state than after ongoing SPW-R-oscillations. However, the increase in amplitude was not significantly different from values derived from the atropine control (p<0.05, CCh vs. SPW-R: p<0.01, CCh vs. atropine: p>0.05, ANOVA with post-hoc test between groups). C: Population spike amplitude in CA1 str. pyramidale (upper panel) and the slope of field-EPSPs in CA1 str. radiatum (lower panel) are potentiated after gamma oscillations. Intakes depict representative waveforms before (black) and after gamma (red).
