Cortical Alpha Oscillations Predict Speech Intelligibility
Understanding speech in noise (SiN) is a complex task involving sensory encoding and cognitive resources including working memory and attention. Previous work has shown that brain oscillations, particularly alpha rhythms (8-12 Hz) play important roles in sensory processes involving working memory and attention. However, no previous study has examined brain oscillations during performance of a c...
متن کاملSuppressed alpha oscillations predict intelligibility of speech and its acoustic details.
Modulations of human alpha oscillations (8-13 Hz) accompany many cognitive processes, but their functional role in auditory perception has proven elusive: Do oscillatory dynamics of alpha reflect acoustic details of the speech signal and are they indicative of comprehension success? Acoustically presented words were degraded in acoustic envelope and spectrum in an orthogonal design, and electro...
متن کاملIntra-cortical propagation of EEG alpha oscillations
The most salient feature of spontaneous human brain activity as recorded with electroencephalography (EEG) are rhythmic fluctuations around 10Hz. These alpha oscillations have been reported to propagate over the scalp with velocities in the range of 5-15m/s. Since these velocities are in the range of action potential velocities through cortico-cortical axons, it has been hypothesized that the o...
متن کاملPre-cue fronto-occipital alpha phase and distributed cortical oscillations predict failures of cognitive control.
Cognitive control is required for correct performance on antisaccade tasks, including the ability to inhibit an externally driven ocular motor response (a saccade to a peripheral stimulus) in favor of an internally driven ocular motor goal (a saccade directed away from a peripheral stimulus). Healthy humans occasionally produce errors during antisaccade tasks, but the mechanisms associated with...
متن کاملOscillations corticales et intelligibilité de la parole dégradée (Oscillatory cortical activity and intelligibility of degraded speech) [in French]
________________________________________________________________________________________________________ Oscillatory cortical activity and intelligibility of degraded speech Many neurocognitive aspects associated with the processing of speech were up to now studied by the analysis of event-related potentials. However, none of these cortical responses can be considered as a direct indicator of s...
