| summary | Language and music are two primary channels of human communication, and their similarities have long interested scholars. The present talk focuses on syntactic processing, i.e., the arrangement of discrete elements into structured sequences, as one aspect that is central to both domains.
Recent behavioural and ERP studies proposed shared cognitive resources of musical and linguistic syntax processing (Patel, 2003) by showing that linguistic and musical syntax processing interact (Fedorenko et al., in press, Koelsch et al., 2005, Slevc et al., in press, Steinbeis et al., 2008), that musical training may enhance linguistic syntax processing (Jentschke et al., 2005), and that agrammatical language disorders are accompanied by parallel deficits in the processing of musical syntax (Jentschke et al., 2008, Patel et al., 2008).
The present work set out to test the hypothesis of a neuroanatomical
co-localisation of musical and linguistic syntax processing in the human brain, particularly within the inferior frontal and the superior temporal lobes. To this end, event-related potentials (ERP) were recorded in an auditory sentence comprehension paradigm (Friederici et al., 1993) and a chord sequence paradigm (Koelsch et al., 2000). The neuroanatomical correlates of ERP components that reflect syntactic structure building in language (ELAN) and music (ERAN) were analysed by means of a lesion experiment, as well as by distributed source modelling of the intracranial equivalents of the ELAN and ERAN recorded from subdural grid electrodes. The combined results support the notion of partially overlapping neuroanatomical substrates of musical and linguistic syntax processing
within the inferior frontal and superior temporal lobes, thus, proposing a rather domain-general role of these areas in the detection of syntactic irregularities within sequential auditory information. |
