Motor origin of temporal predictions in auditory attention

Proceedings of the National Academy of Sciences, Journal Year: 2017, Volume and Issue: 114(42)

Published: Oct. 2, 2017

Significance How the motor system participates in auditory perception is unknown. In a magnetoencephalography experiment involving temporal attention, we show that left sensorimotor cortex encodes predictions, which drive precise anticipation of forthcoming sensory inputs. This encoding associated with bursts beta (18–24 Hz) neural oscillations are directed toward regions. Our data also production overt movements improves quality predictions and augments task performance. These behavioral changes increased signaling right-lateralized frontoparietal associative study points at covert form active sensing, emphasizes fundamental role brain areas actual behavior processing.

Beta Oscillations in Working Memory, Executive Control of Movement and Thought, and Sensorimotor Function

Journal of Neuroscience, Journal Year: 2019, Volume and Issue: 39(42), P. 8231 - 8238

Published: Oct. 16, 2019

Beta oscillations (∼13 to 30 Hz) have been observed during many perceptual, cognitive, and motor processes in a plethora of brain recording studies. Although the function beta (hereafter “beta” for short) is unlikely be explained by any single monolithic description, we here discuss several convergent findings. In prefrontal cortex (PFC), increased appears at end trial when working memory information needs erased. A similar “clear-out” might apply stopping action long-term retrieval (stopping thoughts), where also observed. different apparent role PFC occurs delay period tasks: it serve maintain current contents and/or prevent interference from distraction.

Human motor cortical beta bursts relate to movement planning and response errors

PLoS Biology, Journal Year: 2019, Volume and Issue: 17(10), P. e3000479 - e3000479

Published: Oct. 4, 2019

Motor cortical beta activity (13–30 Hz) is a hallmark signature of healthy and pathological movement, but its behavioural relevance remains unclear. Using high-precision magnetoencephalography (MEG), we show that during the classical event-related desynchronisation (ERD) synchronisation (ERS) periods, motor in individual trials (n > 12,000) dominated by high amplitude, transient, infrequent bursts. Beta burst probability closely matched trial-averaged amplitude both pre- post-movement bursts were spatially more focal than ERS peak. Furthermore, prior to movement (ERD period), timing was related degree preparation, with later resulting delayed response times. Following (ERS first approximately 100 milliseconds when an incorrect made. Overall, stronger predictor single trial behaviour rate or amplitude. This transient nature provides new constraints for theories role information processing within across circuits, functional movement.

EEGpower spectral measures of cognitive workload: A meta‐analysis

Psychophysiology, Journal Year: 2022, Volume and Issue: 59(6)

Published: Feb. 6, 2022

Abstract Cognitive workload (CWL) is a fundamental concept in the assessment and monitoring of human performance during cognitive tasks. Numerous studies have attempted to objectively continuously measure CWL using neuroimaging techniques. Although electroencephalogram (EEG) widely used technique, impact on spectral power brain frequencies has shown inconsistent results. The present review aimed synthesize results literature quantitatively assess which frequency most sensitive CWL. A systematic search following PRISMA recommendations highlighted three main bands CWL: theta (4–8 Hz), alpha (8–12 beta (12–30 Hz). Three meta‐analyses were conducted examine effect these frequencies. total 45 sizes from 24 involving 723 participants computed. was associated with significant effects ( g = 0.68, CI [0.41, 0.95]), −0.25, [−0.45, 0.04]), 0.50, [0.21, 0.79]) power. Our suggests that theta, especially frontal best index Alpha also significantly impacted by CWL; however, their association seemed less straightforward. These are critically analyzed considering cerebral oscillations. We conclude emphasizing need investigate interaction between other factors may influence (e.g., emotional load), combine this methods analysis central peripheral nervous system functional connectivity, heart rate).

Alpha oscillations (7–13 Hz) are the dominant rhythm in both resting and active brain. Accordingly, translational research has provided evidence for involvement of aberrant alpha activity onset symptomatological features underlying syndromes such as autism, schizophrenia, major depression, Attention Deficit Hyperactivity Disorder (ADHD). However, findings on matter difficult to reconcile due variety paradigms, analyses, clinical phenotypes at play, not mention recent technical methodological advances this domain. Herein, we seek address issue by reviewing literature gathered topic over last ten years. For each neuropsychiatric disorder, a dedicated section will be provided, containing concise account current models proposing characteristic alterations rhythms core mechanism trigger associated symptomatology, well summary most relevant studies scientific contributions issued throughout decade. We conclude with some advice recommendations that might improve future inquiries within field.

Abstract Information processing in the brain is governed by oscillatory activity. Activity oscillations specific frequency bands (theta, alpha, beta and gamma) have been associated with various cognitive functions. A drawback of this that plethora findings led to considerable uncertainty as functional relevance activity different their interrelation. Here, we use a novel cognitive-science theoretical framework better understand conceptually harmonize neurophysiological research on human action control. We outline how validated starting point can systematize probably reframe relevant for control beyond.

Beta: bursts of cognition

Trends in Cognitive Sciences, Journal Year: 2024, Volume and Issue: 28(7), P. 662 - 676

Published: April 23, 2024

Beta oscillations are linked to the control of goal-directed processing sensory information and timing motor output. Recent evidence demonstrates they not sustained but organized into intermittent high-power bursts mediating timely functional inhibition. This implies there is a considerable moment-to-moment variation in neural dynamics supporting cognition. thus offer new opportunities for studying how inputs selectively processed, reshaped by inhibitory cognitive operations ultimately result actions. method advances reveal diversity beta that provide deeper insights their function underlying circuit activity motifs. We propose brain-wide, spatiotemporal patterns bursting reflect various nonlinear aspects cortical processing.

Investigating the Spatio‐Temporal Signatures of Language Control–Related Brain Synchronization Processes

Human Brain Mapping, Journal Year: 2025, Volume and Issue: 46(2)

Published: Jan. 21, 2025

ABSTRACT Language control processes allow for the flexible manipulation and access to context‐appropriate verbal representations. Functional magnetic resonance imaging (fMRI) studies have localized brain regions involved in language usually by comparing high vs. low lexical–semantic conditions during tasks. Yet, spectro‐temporal dynamics of associated remain unexplored, preventing a proper understanding neural bases mechanisms. To do so, we recorded functional activity using magnetoencephalography (MEG) fMRI, while 30 healthy participants performed silent verb generation (VGEN) picture naming (PN) task upon confrontation with pictures requiring or processes. fMRI confirmed association between stronger increased left inferior frontal gyrus (IFG) perfusion, MEG revealed these controlled mechanisms be specific sequence early (< 500 ms) late (> beta‐band (de)synchronization within fronto‐temporo‐parietal areas. Particularly, modulations event‐related were first observed right IFG, followed bilateral IFG temporo‐parietal regions. Altogether, results suggest that beyond recruitment regions, rely on complex temporal oscillatory over antero‐posterior
