Here, we use the term “syntax” as employed in previous brain imaging studies of music ( Maess et al. The most substantial of the proposed links between music and language relates to syntax-the rules governing how musical or linguistic elements can be combined and expressed over time ( Lerdahl and Jackendoff 1983). 2009), there is great interest in understanding the extent to which the neural resources deployed for processing music and speech are distinctive or shared ( Patel 2003, 2008). Because of the ecological and behavioral significance of music and speech in human culture and evolution ( Brown et al. Music and speech are human cultural universals ( Brown 1991) that manipulate acoustically complex sounds. While agreeing with previous findings that music and speech processing share neural substrates, this work shows that temporal structure in the 2 domains is encoded differently, highlighting a fundamental dissimilarity in how the same neural resources are deployed.Īuditory brainstem, auditory cortex, music, speech, syntax Introduction ![]() Distributed neuronal populations that included the inferior frontal cortex, the posterior and anterior superior and middle temporal gyri, and the auditory brainstem classified temporal structure manipulations in music and speech with significant levels of accuracy. Although the same manipulation of temporal structure elicited brain activation level differences of similar magnitude for both music and speech stimuli, multivariate classification analysis revealed distinct spatial patterns of brain responses in the 2 domains. Heart rate variability and mean respiration rates were simultaneously measured and were found not to differ between musical and speech stimuli. Here, we use functional magnetic resonance imaging to measure brain activity patterns in 20 right-handed nonmusicians as they listened to natural and temporally reordered musical and speech stimuli matched for familiarity, emotion, and valence. Music and speech are complex sound streams with hierarchical rules of temporal organization that become elaborated over time.
