Neural Resonance Theory: Entrainment to Missing Pulse Rhythms
نویسندگان
چکیده
Many rhythm perception experiments employ simple isochronous rhythms, in which synchronous neural or behavioral responses are observed. However, responses at the stimulus frequency do not allow one to distinguish whether synchrony occurs as a response to common input, or as the result of an emergent population oscillation that entrains at a particular frequency. This study aimed to investigate whether the sensorimotor system, as measured by 32channel cortical EEG, would entrain to a complex rhythm at the pulse frequency even when the complex rhythm contained no spectral power at that frequency. Dynamical analysis predicts neural oscillation will emerge at such a “missing” pulse frequency. We report evidence of response in the EEG to missing 2 Hz pulse rhythms. These data support the theory that rhythmic synchrony occurs as the result of an emergent population oscillation that entrains at this particular frequency. We also discuss generators of the missing pulse response.

Neural Entrainment to the Beat: The "Missing-Pulse" Phenomenon.
Most humans have a near-automatic inclination to tap, clap, or move to the beat of music. The capacity to extract a periodic beat from a complex musical segment is remarkable, as it requires abstraction from the temporal structure of the stimulus. It has been suggested that nonlinear interactions in neural networks result in cortical oscillations at the beat frequency, and that such entrained o...
متن کاملNeural Networks for Beat Perception in Musical Rhythm
Entrainment of cortical rhythms to acoustic rhythms has been hypothesized to be the neural correlate of pulse and meter perception in music. Dynamic attending theory first proposed synchronization of endogenous perceptual rhythms nearly 40 years ago, but only recently has the pivotal role of neural synchrony been demonstrated. Significant progress has since been made in understanding the role o...
متن کاملNeural Entrainment to Polyrhythms: A Comparison of Musicians and Non-musicians
Music can be thought of as a dynamic path over time. In most cases, the rhythmic structure of this path, such as specific sequences of strong and weak beats or recurring patterns, allows us to predict what and particularly when sounds are going to happen. Without this ability we would not be able to entrain body movements to music, like we do when we dance. By combining EEG and behavioral measu...
متن کاملPulse Detection in Syncopated Rhythms Using Neural Oscillators
Pulse and meter are remarkable in part because these perceived periodicities can arise from rhythmic stimuli that are not periodic. This phenomenon is most striking in syncopated rhythms, found in many genres of music, including music of non-Western cultures. In general, syncopated rhythms may have energy at frequencies that do not correspond to perceived pulse or meter, and perceived metrical ...
متن کاملWhat can we learn about beat perception by comparing brain signals and stimulus envelopes?
Entrainment of neural oscillations on multiple time scales is important for the perception of speech. Musical rhythms, and in particular the perception of a regular beat in musical rhythms, is also likely to rely on entrainment of neural oscillations. One recently proposed approach to studying beat perception in the context of neural entrainment and resonance (the "frequency-tagging" approach) ...
