This study reveals the tonotopy-and retinotopy-dependent intrinsic functional connectivity (iFC) across cortical depths in the human auditory and visual cortieces, respectively. Using 7T fMRI data with 1-mm isotripic resolution, we demonstrated that feature-dependent iFC have a higher selectivity in the primary sensory than in the secondary sensory area. The selectivity was generally higher as we moved from superficial to deep cortical depths, while the difference between the primary sensory and secondary sensory area was more prominent in the intermediate cortical depth.
