Selective neuronal entrainment to the beat and meter embedded in a musical rhythm.

چکیده
Fundamental to the experience of music, beat and meter perception refers to the perception of periodicities while listening to music occurring within the frequency range of musical tempo. Here, we explored the spontaneous building of beat and meter hypothesized to emerge from the selective entrainment of neuronal populations at beat and meter frequencies. The electroencephalogram (EEG) was recorded while human participants listened to rhythms consisting of short sounds alternating with silences to induce a spontaneous perception of beat and meter. We found that the rhythmic stimuli elicited multiple steady state-evoked potentials (SS-EPs) observed in the EEG spectrum at frequencies corresponding to the rhythmic pattern envelope. Most importantly, the amplitude of the SS-EPs obtained at beat and meter frequencies were selectively enhanced even though the acoustic energy was not necessarily predominant at these frequencies. Furthermore, accelerating the tempo of the rhythmic stimuli so as to move away from the range of frequencies at which beats are usually perceived impaired the selective enhancement of SS-EPs at these frequencies. The observation that beat- and meter-related SS-EPs are selectively enhanced at frequencies compatible with beat and meter perception indicates that these responses do not merely reflect the physical structure of the sound envelope but, instead, reflect the spontaneous emergence of an internal representation of beat, possibly through a mechanism of selective neuronal entrainment within a resonance frequency range. Taken together, these results suggest that musical rhythms constitute a unique context to gain insight on general mechanisms of entrainment, from the neuronal level to individual level.

Exploring how musical rhythm entrains brain activity with electroencephalogram frequency-tagging.
The ability to perceive a regular beat in music and synchronize to this beat is a widespread human skill. Fundamental to musical behaviour, beat and meter refer to the perception of periodicities while listening to musical rhythms and often involve spontaneous entrainment to move on these periodicities. Here, we present a novel experimental approach inspired by the frequency-tagging approach to...
متن کاملThree Things Linguists Need to Know About Rhythm and Time in Music
This paper, directed at researchers in linguistics, introduces three key aspects of musical rhythm and time for their consideration: (1) the distinction between groups of durations (i.e., acoustical events in the world) and our endogenous sense of beats and beat cycles, that is, musical meter; (2) the active nature of rhythmic perception and cognition, which involves both innate and enculturate...
متن کاملTagging the neuronal entrainment to beat and meter.
Feeling the beat and meter is fundamental to the experience of music. However, how these periodicities are represented in the brain remains largely unknown. Here, we test whether this function emerges from the entrainment of neurons resonating to the beat and meter. We recorded the electroencephalogram while participants listened to a musical beat and imagined a binary or a ternary meter on thi...
متن کاملAutomatic Characterization of Digital Music for Rhythmic Auditory Stimulation
A computational rhythm analysis system is proposed to characterize the suitability of musical recordings for rhythmic auditory stimulation, a neurologic music therapy technique that uses rhythm to entrain periodic physical motion. Current applications of RAS are limited by the general inability to take advantage of the enormous amount of digital music that exists today. The system aims to ident...
متن کاملGetting the beat: Entrainment of brain activity by musical rhythm and pleasantness
Rhythmic entrainment is an important component of emotion induction by music, but brain circuits recruited during spontaneous entrainment of attention by music and the influence of the subjective emotional feelings evoked by music remain still largely unresolved. In this study we used fMRI to test whether the metric structure of music entrains brain activity and how music pleasantness influence...
