(a) Within cytoarchitectonically-defined bilateral primary auditory cortex (blue outline), we conducted a second-level within-subjects F test to identify voxels in which activity for SCN (relative to the mean over scans) differed significantly by imaging sequence. For two peaks resulting from this contrast, parameter estimates (top) and t-statistics (bottom) were extracted to illustrate the data driving the effect. (b) Whole-brain analysis to look for regions showing more activity for Sentences than SCN, averaged over scanning sequence, p < .005 voxelwise threshold corrected for whole-brain significance using cluster extent (p < .05). For five peaks resulting from this contrast, parameter estimates and t-statistics were extracted to examine the effects of imaging sequence on neural activity; *indicates significant ANOVA for a difference by sequence. MNI coordinates for extracted maxima are given above each plot. Abbreviations: Qu = Quiet, Sp = Sparse, St = Standard, MSt = Matched Standard sequence. Error bars represent 1 standard error of the mean with between-subjects variance removed, suitable for within-subjects comparisons.
