Abstract
This talk will first give a brief overview over theoretical concepts
of musical syntax. Then studies using the early right anterior
negativity (ERAN) as an electrophysiological index of
music-syntactic processing will be reviewed. The ERAN is usually
occurs at around 150 - 200 ms after the onset of a musical event,
and receives main contributions from the inferior fronto-lateral
cortex (Broca's area and its right-hemispheric homotope). The ERAN
is taken as an index of a disruption of musical structure building.
Although the morphology of the ERAN is reminiscent of that of the
mismatch negativity (MMN), there are important functional
differences between ERAN and MMN. For example, the regularities
underlying the generation of the MMN are established on-line (that
is, based on on representations of regularities that are extracted
on-line from the acoustic environment). By contrast, the generation
of the ERAN requires (implicit) knowledge about regularities (that
is, representations of regularities that are stored in a long-term
format). Furthermore, the generation of the MMN is based on local
dependencies, whereas the generation of the ERAN involves processing
of long-distance dependencies at the level of phrase-structure
grammar (context-free grammar).
