We explored the functional connectivity of the human auditory cortex with cortical depth analysis and compared music listening and the resting state using 7T fMRI with 0.8 mm isotropic resolution. Tonotopic maps, principal component analysis, and seed-based correlation revealed network topologies and suggested functions supporting feed-forward and feed-back processing. The feed-forward process is manifested by the reduced correlation to the contralateral auditory cortex during music-listening at the intermediate cortical depths. The feed-back processing is associated with a network like the tonotopic organization, which was stable between the resting and music listening but more correlated with the contralateral auditory cortex.
