Time constant of behavioral states. (A) Example of whisking trace and LFP responses to two closely spaced microstimulations. The time of microstimulation is indicated using black arrows. The significant difference in LFP response shows that evoked responses to microstimulation are rapidly modulated by changes in motor behavior. (B) The correlation between LFP oscillation power and whisking strength is plotted at different time lags with the correlation (R) on the Y-axis and the ‘P’ value of each correlation indicated in red. Note that the correlations are negative with the highest magnitude of correlation (−0.50) occurring at 0 lag. The rapid drop-off in the correlation implies rapid switching of behavioral states.
