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) ...

Experimental evidence suggests a functional significance of EEG alpha rhythms. Event-related, evoked, and induced alpha rhythms may have functional correlates in primary sensory processing and preparatory processes. These results are in accordance with the view that spontaneous and induced EEG alpha rhythms have quasi-deterministic properties.

Circaseptan (Weekly) Rhythms in Smoking Cessation Considerations Smokers’ rhythms in contemplating quitting or making quit attempts are poorly understood. Tobacco control has focused on annual events (eg, New Year’s Day), but circaseptan (weekly) time cycles may likewise exist. For example, many illnesses such as strokes are more common on Mondays.1 Do cessation behaviors also have weekly rhythms?

Circadian rhythms are of major importance in mammalian physiology and disease. In this review, we give an overview of the present knowledge on origination of circadian rhythms. We discuss the development of both master and peripheral clocks and compare the origination of circadian rhythms in utero and in vitro.

Animals with habitats in the intertidal zone often display biological rhythms that coordinate with both the tidal and the daily environmental cycles. Two recent studies show that the molecular components of the biological clocks mediating tidal rhythms are likely different from the phylogenetically conserved components that mediate circadian (daily) rhythms.

Parkinson's disease (PD) adversely affects timing abilities. Beat-based timing is a mechanism that times events relative to a regular interval, such as the "beat" in musical rhythm, and is impaired in PD. It is unknown if dopaminergic medication influences beat-based timing in PD. Here, we tested beat-based timing over two sessions in participants with PD (OFF then ON dopaminergic medication) a...

Circadian rhythms occur in most of the living organisms, and with a 24 hour periodicity govern a number of physiological and metabolic functions. During the past few years, an important research effort has uncovered new trails that intersect between circadian rhythms and metabolic pathways. At a molecular level, the clock machinery is responsible for the establishment of a circadian epigenome, ...

Wavelet packet decomposition is used to investigate the time-varying characteristics of clinical EEG signals. On the basis of the nonstationary nature of clinical EEG rhythms, wavelet packet analysis is employed for designing filters with different frequency characteristics to detect 4 kinds of EEG rhythms. The coefficients of wavelet transformation corresponding to the rhythms are used to form...

Traditionally, rhythmic similarity measures are compared according to how well rhythms may be recognized with them, how efficiently they can be retrieved from a data base, or how well they model human perception and cognition. In contrast, here similarity measures are compared on the basis of how much insight they provide about the structural inter-relationships that exist within families of rh...
