“…This is similar to AV modulation in AV speech studies showing that congruent visual cues coming before the audio signal starts, modulate audio perception by predicting the upcoming sound. In the current study, musicians showed more alpha desynchronization than non-musicians, which is consistent with previous research, observing different alpha modulation in musicians in speech (Kühnis et al, 2014) and music tasks (Overman et al, 2003) compared to non-musicians. The current results indicating that when the visual cues predict the upcoming sound, musicians compared to non-musicians had more alpha desynchronization in AV speech as a result of focusing their attention to the visual cues compared to auditory speech perception.…”

In audiovisual speech perception, visual information from a talker's face during mouth articulation is available before the onset of the corresponding audio speech, and thereby allows the perceiver to use visual information to predict the upcoming audio. This prediction from phonetically congruent visual information modulates audiovisual speech perception and leads to a decrease in N1 and P2 amplitudes and latencies compared to the perception of audio speech alone. Whether audiovisual experience, such as with musical training, influences this prediction is unclear, but if so, may explain some of the variations observed in previous research. The current study addresses whether audiovisual speech perception is affected by musical training, first assessing N1 and P2 event-related potentials (ERPs) and in addition, inter-trial phase coherence (ITPC). Musicians and non-musicians are presented the syllable, /ba/ in audio only (AO), video only (VO), and audiovisual (AV) conditions. With the predictory effect of mouth movement isolated from the AV speech (AV−VO), results showed that, compared to audio speech, both groups have a lower N1 latency and P2 amplitude and latency. Moreover, they also showed lower ITPCs in the delta, theta, and beta bands in audiovisual speech perception. However, musicians showed significant suppression of N1 amplitude and desynchronization in the alpha band in audiovisual speech, not present for non-musicians. Collectively, the current findings indicate that early sensory processing can be modified by musical experience, which in turn can explain some of the variations in previous AV speech perception research.

“…Such differences have been demonstrated for the preattentive processing of auditory stimuli [e.g., Brattico et al, 2001;Koelsch et al, 1999;van Zuijen et al, 2004], the processing of temporal patterns [Drake et al, 2000;Jongsma et al, 2004], pitch memory [Gaab and Schlaug, 2003], as well as the processing of harmonic and melodic information [Overman et al, 2003;Schmithorst and Holland, 2003]. On the other hand, music can be enjoyed and understood also by nonmusicians to a considerable degree, as demonstrated by, e.g., Koelsch et al [2000Koelsch et al [ , 2003.…”

Neither music nor spoken language form uniform auditory streams, rather, they are structured into phrases. For the perception of such structures, the detection of phrase boundaries is crucial. We discovered electroencephalography (EEG) and magnetoencephalography (MEG) correlates for the perception of phrase boundaries in music. In EEG, this process was marked by a positive wave approximately between 500 and 600 ms after the offset of a phrase boundary with a centroparietal maximum. In MEG, we found major activity in an even broader time window (400-700 ms). Source localization revealed that likely candidates for the generation of the observed effects are structures in the limbic system, including anterior and posterior cingulate as well as posterior mediotemporal cortex. The timing and topography of the EEG effect bear some resemblance to a positive shift (closure positive shift, CPS) found for prosodic phrase boundaries during speech perception in an earlier study, suggesting that the underlying processes might be related. Because the brain structures, which possibly underlie the observed effects, are known to be involved in memory and attention processes, we suggest that the CPS may not reflect the detection of the phrase boundary as such, but those memory and attention related processes that are necessary to guide the attention focus from one phrase to the next, thereby closing the former and opening up the next phrase.

“…The advent of sensory processing (e.g., eyes-opening) has been associated with the phenomenon of alpha desychronization or alpha blocking and associated enhancements in theta, beta and gamma bands [47,70,82,99]. Strictly speaking, alpha desychronization involves a detuning of the alpha rhythm, given that alpha activity across the cortex is at most only phase locked for no more than a fraction of a second.…”

A Framework for Investigating Thalamocortical Activity in Multistage Information Processing

A framework for investigating information processing in cortico-thalamocortical (cortico-TC) networks is presented, that in part can be used to model and interpret individual changes in electroencephalographic spectra and event-related potentials such as those from the Brain Resource International Database. Scientific work covering neurophysiology, TC firing modes, and TC models are explored in the framework to explain how the brain might process complex information in a multistage process. It is proposed that the thalamus and the cortico-TC system have unique ionic properties and transmission delays (in humans), which are suited to the function of taking "snapshots" or samples of complex environmental stimuli, rather than continuous data streams. This leads to careful and sequential coordination of stimulus and response processes, and increases the probability of information transfer and the resulting information complexity in higher cortical regions. Given the scope of this framework, the multidimensional and standardized Brain Resource International Database provides a pertinent set of measures for both testing hypotheses generated from the model, and for fitting the model to experimental data to investigate mechanisms underlying information processing.
