Melody change processing localizes more anteriorly than energy onset in auditory cortex

Evidence

The melody generator was located in the medial part of Heschl’s gyrus (HG); the onset generator about 10 mm more posterior in PT—a common location for the onset N1m. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4703

Categorization

• XREF: Joins the broader literature mapping pitch and onset processing onto Heschl’s gyrus vs. planum temporale distinct generators. — connects to: Melody processing and sound onset recruit distinct auditory cortex regions, roughly 10 mm apart.; Melody and energy-onset generators occupy distinct auditory cortex loci.; Pitch-change sequence processing drives larger N1m and P2m responses than constant notes — Dijk, Pim van, Physiology, Psychoacoustics and…, 4703 (+4 more)
• corroborated: 2 independent passages support this claim — Dijk, Pim van, Physiology, Psychoacoustics and…, 4703
