Figure 4. Normalized power by spectral bands.

Figure 4

A Drug-by-Prior Regulation interaction was found specifically in the slow-4 band, which encompasses oscillations in the 13-37s range. In this band, prior regulation increased power after placebo administration, but this effect was reversed after methylphenidate administration. @=p<0.1.
