We explored the correlation between cortical depth-dependent fMRI signal and oscillatory neural activity during music listening using high-resolution fMRI (7T with 0.8 mm and 3T with 1.5 mm isotropic resolution, respectively) and invasive electrode recording on epilepsy patients. The hemodynamic responses in the auditory cortex were found positively and negatively correlated with neural oscillations in the gamma and alpha/beta band at right and both hemispheres, respectively. These correlations were highest at the intermediate cortical depth. Core and non-core areas of the auditory cortex had different correlations.
