fMRI data were acquired on a 3 T Siemens MAGNETOM Verio MRI scanner with a 12-channel head array. Key presses were recorded using an MR-compatible response keypad (Nata Technologies). Acoustic stimuli were delivered via MR-compatible insert earphones (MR confon HP AT01; MR Confon). Participants were equipped with over-ear hearing protectors during the experiment to attenuate scanner background noise. During the selective listening task, 1100 T2*-weighted gradient echo planar imaging volumes with BOLD contrast were obtained (time of repetition [TR] = 2000 ms, time of echo [TE] = 30 ms, flip angle α = 80°, field of view [FoV] = 200 × 200 mm2, voxel-size = 3.1 × 3.1 × 3.0 mm3). Volumes consisted of 31 transverse slices with a gap of 0.9 mm in between and were recorded in an ascending order. The same imaging parameters were used to obtain a resting-state time series consisting of 261 T2* volumes. A high-resolution structural volume was acquired for each participant using a T1-weighted magnetization-prepared rapid acquisition gradient echo sequence (TR = 1900 ms, TE = 2.52 ms, α = 9°, FoV = 256 × 256 mm2, voxel-size = 1 × 1 × 1 mm3).
