Condition-dependent single-trial predictive value of midfrontal theta power
REGRESSION
Based on the results above, we restricted the single-trial analysis to the frequency ranges (beta: 18–26 Hz, theta: 4–8 Hz) and time windows (beta: −1000 ms to −300 ms, theta: −400 ms to 0 ms) for which significant effects of DBS condition were identified in the group level analysis.In the linear mixed model evaluating the relationship between midfrontal theta power, DBS condition and antisaccade latency with participants as random effect, we observed a main effect of condition on antisaccade latency as expected from behavioral findings (χFrom Single-trial mixed linear regression model of the relationship between antisaccade latency (in ms), midfrontal-theta activity (in dB) and DBS condition (off-DBS in black, 130 Hz DBS in red and 60 Hz-DBS in blue) as fixed effects and participants as random effect. Dots represent single trials. Shaded areas represent 95 %-confidence intervals. The (theta × condition) interaction differed significantly between off-DBS and 130 Hz DBS. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)No significant effects of cortical power nor of (power × condition) interactions were identified in the linear mixed-effect model including beta power or in the respective mixed logistic models of error probability.
