Figure 2. Time courses of the BOLD-triggered average of LFP power in different frequency bands under ISO anesthesia (panel A, 32 scans) and DMED anesthesia (panel B, 22 scans).

Figure 2.

The x-axis is the time lag with respect to the BOLD triggers. The y-axis is the normalized LFP power (the standard deviation of broadband LFP power is 1 LFP S.D.). The vertical cursors show the maximally-correlated lag (−4 seconds for ISO in all frequency bands; −2.5 second for DMED in all frequency bands, with an additional line for the negative deviation which is located at −5.5 seconds for Delta band and Broadband, and at −5 seconds for Theta band). Each point in the time courses is the averaged value of roughly 10% of the dataset. The upper threshold and lower threshold for 95% confidence intervals are obtained from the 97.5 and 2.5 percentiles of the noise empirical distribution, respectively. BetaL, low frequency beta 12~25Hz, BetaH, high frequency beta, 25~40Hz.
