Language and music are two human-unique capacities whose relationship remains debated. Some have argued for overlap in processing mechanisms, especially structure processing. Such claims often concern the inferior frontal component of language system located within "Broca's area." However, others failed to find overlap. Using a robust individual-subject fMRI approach, we examined responses brain regions stimuli, probed musical abilities individuals with severe aphasia. Across 4 experiments, obtained clear answer: perception does not engage system, judgments about possible even presence damage network. In particular, regions' generally low, below fixation baseline, never exceed elicited by nonmusic auditory conditions, like animal sounds. Furthermore, sensitive structure: they show low both intact structure-scrambled music, melodies vs. without structural violations. Finally, line past patient investigations, aphasia, who cannot judge sentence grammaticality, perform well on melody well-formedness judgments. Thus, mechanisms that process do appear including syntax.

Speech and music might involve specific cognitive rhythmic timing mechanisms related to differences in the dominant structure. We investigate influence of different motor effectors on rate-specific processing both domains. A perception a synchronization task involving syllable piano tone sequences typically associated with speech (whispering) (finger-tapping) were tested at slow (~2 Hz) fast rates (~4.5 Hz). Although performance was generally better rates, exhibited rate preferences. Finger-tapping advantaged compared whispering but not faster being effector-dependent slow, highly correlated rates. Perception predicted by general finger-tapping component. Our data suggests partially independent for music, possibly differential recruitment cortical circuitry.

Dynamical theories of speech processing propose that the auditory cortex parses acoustic information in parallel at syllabic and phonemic timescales. We developed a paradigm to independently manipulate both linguistic timescales, acquired intracranial recordings from 11 patients who are epileptic listening French sentences. Our results indicate (i) timescales reflected spectral flux; (ii) during comprehension, tracks timescale theta range, while neural activity alpha-beta range phase locks timescale; (iii) these dynamics occur simultaneously share joint spatial location; (iv) flux embeds two timescales-in low-beta ranges-across 17 natural languages. These findings help us understand how human brain extracts continuous signal multiple simultaneously, prerequisite for subsequent processing.

Abstract Speech and music are two fundamental modes of human communication. Lateralisation key processes underlying their perception has been related both to the distinct sensitivity low-level spectrotemporal acoustic features top-down attention. However, interplay between bottom-up needs be clarified. In present study, we investigated contribution acoustics attention melodies or sentences lateralisation in fMRI functional network topology. We used sung speech stimuli selectively filtered temporal spectral modulation domains with crossed balanced verbal melodic content. Perception decreased degradation information, whereas degradation. Applying graph theoretical metrics on connectivity matrices, found that local clustering, reflecting specialisation, linearly increased when cues crucial for task goal were incrementally degraded. These effects occurred a bilateral fronto-temporo-parietal processing temporally degraded right auditory regions spectrally melodies. contrast, global topology remained stable across conditions. findings suggest partially depends an goals under attentional demands.
