N1m and P2m components are separable generators, both enhanced by melodic pitch changes
Evidence
The figure shows that the technique reveals a double dissociation; the N1m is prominent in the N1m temporal window (left panel) but the P2m is not; whereas the P2m is prominent in the P2m temporal window (right panel), but N1m is not. Moreover, the adapted melodic notes (blue) produce a larger P2m (right panel) and a larger N1m (left panel) than the adapted tonic notes (red). — Dijk, Pim van, Physiology, Psychoacoustics and…, 4703
