The human language system, including its inferior frontal component in “Broca’s area,” does not support music perception

Cerebral Cortex, Journal Year: 2023, Volume and Issue: 33(12), P. 7904 - 7929

Published: April 1, 2023

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.

Spectro-temporal acoustical markers differentiate speech from song across cultures

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: June 6, 2024

Abstract Humans produce two forms of cognitively complex vocalizations: speech and song. It is debated whether these differ based primarily on culturally specific, learned features, or if acoustical features can reliably distinguish them. We study the spectro-temporal modulation patterns vocalizations produced by 369 people living in 21 urban, rural, small-scale societies across six continents. Specific ranges spectral temporal modulations, overlapping within categories societies, significantly differentiate from Machine-learning classification shows that this effect cross-culturally robust, being classified solely their all societies. Listeners unfamiliar with cultures classify using similar cues as machine learning algorithm. Finally, are better able to discriminate song than a broad range other variables, suggesting modulation—a key feature auditory neuronal tuning—accounts for fundamental difference between categories.

Music can be reconstructed from human auditory cortex activity using nonlinear decoding models

PLoS Biology, Journal Year: 2023, Volume and Issue: 21(8), P. e3002176 - e3002176

Published: Aug. 15, 2023

Music is core to human experience, yet the precise neural dynamics underlying music perception remain unknown. We analyzed a unique intracranial electroencephalography (iEEG) dataset of 29 patients who listened Pink Floyd song and applied stimulus reconstruction approach previously used in speech domain. successfully reconstructed recognizable from direct recordings quantified impact different factors on decoding accuracy. Combining encoding analyses, we found right-hemisphere dominance for with primary role superior temporal gyrus (STG), evidenced new STG subregion tuned musical rhythm, defined an anterior-posterior organization exhibiting sustained onset responses elements. Our findings show feasibility applying predictive modeling short datasets acquired single patients, paving way adding elements brain-computer interface (BCI) applications.

Does the visual word form area split in bilingual readers? A millimeter-scale 7-T fMRI study

Science Advances, Journal Year: 2023, Volume and Issue: 9(14)

Published: April 5, 2023

In expert readers, a brain region known as the visual word form area (VWFA) is highly sensitive to written words, exhibiting posterior-to-anterior gradient of increasing sensitivity orthographic stimuli whose statistics match those real words. Using high-resolution 7-tesla functional magnetic resonance imaging (fMRI), we ask whether, in bilingual distinct cortical patches specialize for different languages. 21 English-French bilinguals, unsmoothed 1.2-millimeters fMRI revealed that VWFA actually composed several small selective reading, with word-similarity gradient, but near-complete overlap between two 10 English-Chinese however, while most word-specific exhibited similar reading specificity and gradients Chinese English, additional responded specifically writing and, unexpectedly, faces. Our results show acquisition multiple systems can indeed tune cortex differently sometimes leading emergence specialized single language.

Many but not all deep neural network audio models capture brain responses and exhibit correspondence between model stages and brain regions

PLoS Biology, Journal Year: 2023, Volume and Issue: 21(12), P. e3002366 - e3002366

Models that predict brain responses to stimuli provide one measure of understanding a sensory system and have many potential applications in science engineering. Deep artificial neural networks emerged as the leading such predictive models visual but are less explored audition. Prior work provided examples audio-trained produced good predictions auditory cortical fMRI exhibited correspondence between model stages regions, left it unclear whether these results generalize other network and, thus, how further improve this domain. We evaluated model-brain for publicly available audio along with in-house trained on 4 different tasks. Most tested outpredicted standard spectromporal filter-bank cortex systematic correspondence: Middle best predicted primary cortex, while deep non-primary cortex. However, some state-of-the-art substantially worse predictions. recognize speech background noise better than quiet, potentially because hearing imposes constraints biological representations. The training task influenced prediction quality specific tuning properties, overall resulting from multiple generally support promise audition, though they also indicate current do not explain their entirety.
