As known, different brainwave frequencies show synchronies related to different perceptual, motor or cognitive states. Brainwaves have also been shown to synchronize with external stimuli with repetition rates of ca. 10-40 Hz. However, not much is known about responses to periodic auditory stimuli with periodicities found in human rhythmic behavior (i.e. 0.5-5 Hz). In an EEG study we compared responses to periodic stimulations (drum sounds and clicks with repetition rates of 1-8 Hz), silence… Expand
Entrainment and synchronization of brain oscillations to auditory stimulations
TLDR
Recent advances in understanding how rhythmic auditory stimulation can selectively modulate EEG oscillations are discussed, with stressed that the complexity of the elicited modulations requires time-frequency measures that are better appropriate to analyze driven brain phenomena. Expand
Low-Frequency Cortical Oscillations Entrain to Subthreshold Rhythmic Auditory Stimuli
TLDR
Results indicate that phase alignment is a general mechanism of the brain to process rhythmic structure and can occur without the perceptual detection of this temporal structure, and support the proposition that entrainment of low-frequency oscillations serves a mechanistic role in enhancing perceptual sensitivity for temporally predictive sounds.

Efficacy study of embedded binaural beats in gamma brainwave synchronization
Electrical impulses and chemical activities in human brain generate brain waves at frequency domains ranging between 0.5 Hz and 100 Hz that characterize different mental states. The states ofExpand

Auditory rhythms entrain visual processes in the human brain: Evidence from evoked oscillations and event-related potentials
TLDR
The findings indicate that rhythmic expectations are supported by a reorganization of neural oscillations that seems to benefit stimulus processing at expected time points and supports the idea that entrainment of neuronal oscillations represents a general mechanism through which the brain uses predictive elements in the environment to optimize attention and stimulus perception. Expand
Detection of Near-Threshold Sounds is Independent of EEG Phase in Common Frequency Bands
TLDR
It is shown that effects are artifacts from phase distortion at stimulus onset by contamination with the event-related potential, which differs markedly for hits and misses, which highlights the need to carefully deal with this common problem, since otherwise it might bias and mislead this exciting field of research. Expand
Cumulative effects of theta binaural beats on brain power and functional connectivity
TLDR
The results showed that 3 min of 7 Hz binaural beats is not enough to entrain the brain, but applying 6  min of stimulation could change the relative power in the temporal and parietal lobes and further exposure to 9 Min of stimuli could also alter the brain network, evaluated by the graph theory.

Neural Networks for Beat Perception in Musical Rhythm
TLDR
A neurodynamic model is described that shows how self-organization of oscillations in interacting sensory and motor networks could be responsible for the formation of the pulse percept in complex rhythms and provides a theoretical link between oscillatory neurodynamics and the induction of pulse and meter in musical rhythm. Expand
Phase Entrainment of Human Delta Oscillations Can Mediate the Effects of Expectation on Reaction Speed
TLDR
The results suggest that low-frequency oscillations play a functional role in human anticipatory mechanisms, presumably by modulating synchronized rhythmic fluctuations in the excitability of large neuronal populations and by facilitating efficient task-related neuronal communication among brain areas responsible for sensory processing and response execution.

A 40-Hz auditory potential recorded from the human scalp.
TLDR
It is shown that these waves combined to form a single, stable, composite wave when the sounds are repeated at rates around 40 per sec, which suggests that adequate processing of sensory information may require cyclical brain events in the 30- to 50-Hz range. Expand
Gamma-band activity reflects the metric structure of rhythmic tone sequences.
TLDR
It is shown that induced (non-phase-locked) GBA predicts tone onsets and persists when expected tones are omitted, and is strongly diminished during tone omissions, which provide evidence for the dynamic allocation of attention to temporally structured auditory sequences. Expand
Modulation of spectral power and of phase resetting of EEG contributes differentially to the generation of auditory event-related potentials
TLDR
The results show that both increased spectral power and partial phase resetting contribute differentially to different ERPs, and show that certain ERPs could arise through reorganization of the phase of ongoing scalp EEG activity only. Expand
Stimulus Specificity of Phase-Locked and Non-Phase-Locked 40 Hz Visual Responses in Human
TLDR
This work tested the stimulus specificity of high-frequency oscillations in humans using three types of visual stimuli: two coherent stimuli (a Kanizsa and a real triangle) and a noncoherent stimulus (“no-triangle stimulus”). Expand

Evidence is presented that EEG oscillations in the alpha and theta band reflect cognitive and memory performance in particular. Good performance is related to two types of EEG phenomena (i) a tonicExpand
Resonance in the Perception of Musical Pulse
A number of phenomena related to the perception of isochronous tone sequences peak at a certain rate (or tempo) and taper off at both slower and faster rates. In the present paper we start from theExpand
Latent inhibition mediates N1 attenuation to repeating sounds.
TLDR
The results show that N1 attenuation cannot be due simply to refractoriness, which would elicit the smallest N1 to the second tone, and shows that an inhibitory neural circuit can account for these and previous results. Expand
The N1 wave of the human electric and magnetic response to sound: a review and an analysis of the component structure.
TLDR
It is concluded that at least six different cerebral processes can contribute to the Nl wave of the human auditory evoked potential, and that they often last much longer than the true N1 components that they overlap. Expand
A compound P300-40 Hz response of the cat hippocampus.
TLDR
The analysis shows clearly that the 40 Hz response component is not only a cortical response pattern, but also a universal building block of brain responsiveness and should be correlated with multimodal sensory and cognitive function. Expand
A compound P300-40 Hz response of the cat hippocampus.
In companion reports (Basar-Eroglu et al., in press a,b) it was shown that the hippocampal P300 response had a frequency content with prominent theta enhancement, especially near CA3 region.Expand
