Figure 4.

Single-subject (S4, S5, and S6) intracortical (b) (myelin-related), tonotopic (c and e), and tuning width (e) maps as obtained in session 1 (“tones”; c) and session 2 (“natural sounds”; d and e). Anatomical contrast and functional maps are projected on the individual reconstructed surfaces of both hemispheres. Macroanatomical features (HG) and the highly myelinated region in the auditory cortex are outlined on all maps (solid black and dotted white line, respectively). The cluster resulting in the highest myelin-related content throughout the cortical depth is outlined in red and is reported in (a).
