Figure 2

Comparison of the IOS activity in reflected and transmitted light during epileptic activity evoked by Mg2+-free solution (A) LFP (black) and IOS (red) signal in reflected light. (B) High (IOSh, solid line) and low (IOSl, dashed line) frequency components of the IOS signal. IOSl was calculated by moving window averaging the IOS time series, while IOSh is a result of the subtraction of IOSl from IOS. (C) LFP (black) and IOS (red) signal in transmitted light. (D) IOSh and IOSl in transmitted light. Note, that IOSl were negative in both the reflected and the transmitted measurements, while the negative IOSh changed its sign in the transmitted setup.
