Fig. 5: EEG reveals stimulus-brain coupling.
From: Rapid modulation in music supports attention in listeners with attentional difficulties
a For Experiment 3, we conducted hertz-by-hertz Morlet wavelet analysis of each acoustic stimulus (amplitude-modulated and control) and evaluated the phase-locking value (stimulus-brain coupling) between acoustics of the stimulus and the EEG. Red trace = Mean ± SE Phase Locking Values (PLVs) of frontocentral electrodes for AM + Music. Black trace = Mean ± SE PLVs of the same electrodes for the Control − Music. Results show peaks of phase-locking activity at the note rates and its harmonics (8, 16, 24, 32 Hz) as well as the amplitude-modulated frequencies (12, 14, 16 Hz). b Topographic distributions of the peaks of phase-locked activity at 8, 16, and 32 Hz for amplitude-modulated and control stimuli.
