Tracking: Response profiles in rAA (Top), lSM (Middle), and rSM (Bottom) cortex. PAC estimates were computed between the phase of the 3-Hz melody (A) or 1.5-Hz beat dynamics (B) and brain amplitude in the range of 4–50 Hz for tracking correct trials. Shaded error bars indicate SEM. (C) Time courses of the evoked responses to tones (black, targets; gray, distractors) for tracking correct trials. Dashed lines represent tone onset. (D) Time-frequency statistical maps of the contrast between targets and distractors tracking correct trials. Dashed lines schematize the alternation of targets and distractors at 3 Hz. (E) Time courses of the evoked response to the 1.5-Hz reference beats for tracking correct trials. Dashed lines represent the 1.5-Hz beat. Shaded vertical bars highlight significant effects. Signals were low-pass-filtered in C and E at 30 Hz for display purpose. Maps were interpolated for display purpose in D [n = 19; paired t tests (A–D) or one-tail t tests against zero (E), P < 0.05, FDR-corrected].
