Chirp onset and entrainment responses mask regions. The present map represents the whole sample’s mean inter-trial coherence of the chirp-evoked oscillatory response, with rectangles focusing on areas of maximum inter-trial coherence. The white rectangle shows the chirp onset response region (0–500 ms), and the black rectangle shows the chirp entrainment response region (750–2500 ms), within which time–frequency points with ITC ≥ 0.13 were selected and masked
