Areas within the auditory cortex that are sensitive to FFR–f₀ strength. a, Coronal, sagittal, and horizontal brain slices showing statistical maps where BOLD signal was related to FFR–f₀ strength for each stimulus set; greater FFR strength was related to higher BOLD signal in the right planum temporale (speech: orange; piano: blue). Overlapping regions are indicated in maroon. Bilateral ROIs encompassing the auditory cortex bilaterally are delineated in pink. b, Horizontal slice showing the location of FFR–f₀ sensitive cortex in both conditions (maroon) in relation to the previous result of a right auditory cortex contribution to the FFR–f₀ from MEG (Coffey et al., 2016b). Note that fMRI and MEG differ in their spatial resolution.
