Study 2 Functional Imaging Data: Response in Subcortical Structures
Entropy increase (p < 0.001, uncorrected) (red) and [sound–silence] (p < 0.05, FWE corrected) (blue) contrasts superimposed on a horizontal section (z = −10) of participants' normalised average structural scan that covers IC and MGB (note that z coordinates vary slightly between maxima and arrows, therefore they are only indicative of the exact location). Normalised mean percent BOLD signal change (±SEM) at the local maxima in left and right IC (bottom) and MGB (top) is plotted for the five levels of exponent n.
