Altered neocortical tactile but preserved auditory early change detection responses in Friedreich ataxia
(Clinical Neurophysiology, 2019)Objective: To study using magnetoencephalography (MEG) the spatio-temporal dynamics of neocortical responses involved in sensory processing and early change detection in Friedreich ataxia (FRDA). Methods: Tactile (TERs) ... -
Amodal Atypical Neural Oscillatory Activity in Dyslexia: A Cross-Linguistic Perspective
(Clinical Psychological Science, 2017)It has been proposed that atypical neural oscillations in both the auditory and the visual modalities could explain why some individuals fail to learn to read and suffer from developmental dyslexia. However, the role of ... -
Changes in electrophysiological static and dynamic human brain functional architecture from childhood to late adulthood
(Scientific Reports, 2020)This magnetoencephalography study aimed at characterizing age-related changes in resting-state functional brain organization from mid-childhood to late adulthood. We investigated neuromagnetic brain activity at rest in 105 ... -
Comparing MEG and high-density EEG for intrinsic functional connectivity mapping
(NeuroImage, 2020)Magnetoencephalography (MEG) has been used in conjunction with resting-state functional connectivity (rsFC) based on band-limited power envelope correlation to study the intrinsic human brain network organization into ... -
Comparing the potential of MEG and EEG to uncover brain tracking of speech temporal envelope
(NeuroImage, 2019)During connected speech listening, brain activity tracks speech rhythmicity at delta (∼0.5 Hz) and theta (4–8 Hz) frequencies. Here, we compared the potential of magnetoencephalography (MEG) and high-density electroencephalography ... -
Contrasting functional imaging parametric maps: The mislocation problem and alternative solutions
(NeuroImage, 2018)In the field of neuroimaging, researchers often resort to contrasting parametric maps to identify differences between conditions or populations. Unfortunately, contrast patterns mix effects related to amplitude and ... -
Cortical tracking of lexical speech units in a multi-talker background is immature in school-aged children
(ELSEVIER, 2023)Children have more difficulty perceiving speech in noise than adults. Whether this difficulty relates to an immature processing of prosodic or linguistic elements of the attended speech is still unclear. To address the ... -
Cortical tracking of speech in noise accounts for reading strategies in children
(PLOS BIOLOGY, 2020)Humans’ propensity to acquire literacy relates to several factors, including the ability to understand speech in noise (SiN). Still, the nature of the relation between reading and SiN perception abilities remains poorly ... -
Cortical Tracking of Speech-in-Noise Develops from Childhood to Adulthood
(The Journal of Neuroscience,, 2019)In multitalker backgrounds, the auditory cortex of adult humans tracks the attended speech stream rather than the global auditory scene. Still, it is unknown whether such preferential tracking also occurs in children whose ... -
Corticokinematic coherence as a new marker for somatosensory afference in newborns
(Clinical Neurophysiology, 2017)Objective Somatosensory evoked potentials have high prognostic value in neonatal intensive care, but their recording from infants is challenging. Here, we studied the possibility to elicit cortical responses in newborns ... -
Coupling between human brain activity and body movements: Insights from non-invasive electromagnetic recordings
(NeuroImage, 2019)Electroencephalographic and magnetoencephalographic data have characterized two types of brain–body interactions observed during various types of motor actions, “corticokinematic” and “corticomuscular” coupling. Here, we ... -
Development of neural oscillatory activity in response to speech in children from 4 to 6 years old
(Developmental Science, 2020)Recent neurophysiological theories propose that the cerebral hemispheres collaborate to resolve the complex temporal nature of speech, such that left-hemisphere (or bilateral) gamma-band oscillatory activity would ... -
Effect of interstimulus interval on cortical proprioceptive responses to passive finger movements
(European Journal of Neuroscience, 2017)Shortening of the interstimulus interval (ISI) generally leads to attenuation of cortical sensory responses. For proprioception, however, this ISI effect is still poorly known. Our aim was to characterize the ISI dependence ... -
Effects of PSA Removal from NCAM on the Critical Period Plasticity Triggered by the Antidepressant Fluoxetine in the Visual Cortex
(Frontiers in Cellular Neuroscience, 2016)Neuronal plasticity peaks during critical periods of postnatal development and is reduced towards adulthood. Recent data suggests that windows of juvenile-like plasticity can be triggered in the adult brain by antidepressant ... -
Feasibility and reproducibility of electroencephalography-based corticokinematic coherence
(Journal of Neurophysiology, 2020)Corticokinematic coherence (CKC) is the phase coupling between limb kinematics and cortical neurophysiological signals, reflecting cortical processing of proprioceptive afference, and it is reproducible when estimated with ... -
Frequency-Dependent Intrinsic Electrophysiological Functional Architecture of the Human Verbal Language Network
(Frontiers in Integrative Neuroscience, 2020)Functional magnetic resonance imaging (fMRI) allowed the spatial characterization of the resting-state verbal language network (vLN). While other resting-state networks (RSNs) were matched with their electrophysiological ... -
Impaired neural response to speech edges in dyslexia
(ScienceDirect, 2021)Speech comprehension has been proposed to critically rely on oscillatory cortical tracking, that is, phase alignment of neural oscillations to the slow temporal modulations (envelope) of speech. Speech-brain entrainment ... -
Inaccurate cortical tracking of speech in adults with impaired speech perception in noise
(Brain Communications, 2021)Impaired speech perception in noise despite normal peripheral auditory function is a common problem in young adults. Despite a growing body of research, the pathophysiology of this impairment remains unknown. This ... -
Language Proficiency Entails Tuning Cortical Activity to Second Language Speech
(Cerebral Cortex, 2021)Cortical tracking of linguistic structures in speech, such as phrases (<3 Hz, delta band) and syllables (3–8 Hz, theta band), is known to be crucial for speech comprehension. However, it has not been established whether ... -
Left Superior Temporal Gyrus Is Coupled to Attended Speech in a Cocktail-Party Auditory Scene
(The Journal of Neuroscience, 2016)Using a continuous listening task, we evaluated the coupling between the listener’s cortical activity and the temporal envelopes of different sounds in a multitalker auditory scene using magnetoencephalography and ...
