Fig. 4. Cortical depth-dependence of frequency preference.

Frequency preference, as mapped using 3D GRASE, is shown in the left hemisphere of an individual volunteer. The tonotopic map is shown both at macroscopic level (A) and after zooming in to show frequency preference throughout cortical depth (B). The cortical depth-dependent maps show regions of stable frequency preference (i.e. frequency columns) as well as variations in preference throughout depth. The white dotted line follows the crown of HG (a partial duplication, resulting in 1.5 H G, is present in this hemisphere). Figure adapted from Moerel et al. (2018b).
