Correlation of cortical neural activity and OOA of the right ear. a A nonparametric cluster-based permutation analysis indicated a correlation of brain-AMI and OOA-AMI of the right ear pooled across 0.25–1.95 s of the cue-target interval (p = 0.01). This corresponded to a negative cluster in the observed data incorporating the whole frequency range (3–25 Hz) of the analysis. The number of voxels in this cluster is shown as a function of frequency. The extent of the cluster peaks in the alpha, theta, and beta bands. For the peak in the theta band, the cluster is located in the left STG. For the alpha band, it is located in medial portions of left Heschl’s gyrus and right (pre-)motor areas. For the beta band, it is located in left inferior-medial temporal regions. Orthogonal views represent masked t values (75% threshold). b Correlation of brain-AMI at 6 Hz and OOA-AMI in the most significant voxel from a. c Correlation of brain-AMI at 11–12 Hz and OOA-AMI in the most significant voxel from a. The shaded error bars represent the SEM
