Brain Oscillatory Modes as a Proxy of Stroke Recovery

Dimitri Nestor Alice Van De Ville, Olaf Blanke, Silvestro Micera, Friedhelm Christoph Hummel, Takuya Morishita, Elena Beanato, Sylvain Jean-François Harquel, Lisa Aïcha Mireille Julie Fleury, Nathalie Heidi Meyer, Maximilian Jonas Wessel

Background Stroke is the leading cause of long-term disability, making the search for successful rehabilitation treatment one of the most important public health issues. A better understanding of the neural mechanisms underlying impairment and recovery is ...

Reduced spatial frequency differentiation and sex‐related specificities in fearful face detection in autism: Insights from EEG and the predictive brain model

Sylvain Jean-François Harquel

Face processing relies on predictive processes driven by low spatial frequencies (LSF) that convey coarse information prior to fine information conveyed by high spatial frequencies. However, autistic individuals might have atypical predictive processes, co ...

MEP and TEP features variability: is it just the brain-state?

Friedhelm Christoph Hummel, Estelle Emeline Raffin, Sylvain Jean-François Harquel, Andéol Geoffroy Cadic-Melchior, Michele Bevilacqua, Claudia Bigoni

Objective. The literature investigating the effects of alpha oscillations on corticospinal excitability is divergent. We believe inconsistency in the findings may arise, among others, from the electroencephalography (EEG) processing for brain-state determi ...

Sex modulation of faces prediction error in the autistic brain

Sylvain Jean-François Harquel

Recent research suggests that autistic females may have superior socio-cognitive abilities compared to autistic males, potentially contributing to underdiagnosis in females. However, it remains unclear whether these differences arise from distinct neurophy ...

Physiology-inspired bifocal fronto-parietal tACS for working memory enhancement

Friedhelm Christoph Hummel, Pablo Maceira Elvira, Sylvain Jean-François Harquel, Traian Popa

Aging populations face significant cognitive challenges, particularly in working memory (WM). Transcranial alternating current stimulation (tACS) offer promising avenues for cognitive enhancement, especially when inspired by brain physiology. This study (N ...

Stroke Recovery–Related Changes in Cortical Reactivity Based on Modulation of Intracortical Inhibition

Dimitri Nestor Alice Van De Ville, Olaf Blanke, Silvestro Micera, Takuya Morishita, Elena Beanato, Sylvain Jean-François Harquel, Lisa Aïcha Mireille Julie Fleury, Philip Egger, Giorgia Giulia Evangelista, Pauline Menoud

BACKGROUND: Cortical excitation/inhibition dynamics have been suggested as a key mechanism occurring after stroke. Their supportive or maladaptive role in the course of recovery is still not completely understood. Here, we used transcranial m ...

Modulation of Visually Induced Self-motion Illusions by α Transcranial Electric Stimulation over the Superior Parietal Cortex

Sylvain Jean-François Harquel

The growing popularity of virtual reality systems has led to a renewed interest in understanding the neurophysiological correlates of the illusion of self-motion (vection), a phenomenon that can be both intentionally induced or avoided in such systems, dep ...

Novel personalized treatment strategy for patients with chronic stroke with severe upper-extremity impairment: The first patient of the AVANCER trial

Friedhelm Christoph Hummel, Takuya Morishita, Andrea Crema, Elena Beanato, Sylvain Jean-François Harquel, Maximilian Jonas Wessel, Claudia Bigoni, Giorgia Giulia Evangelista, Sarah Bernardina Zandvliet

Background: Around 25% of patients who have had a stroke suffer from severe upper-limb impairment and lack effective rehabilitation strategies. The AVANCER proof-of-concept clinical trial (NCT04448483) tackles this issue through an intensive and personaliz ...

Motor imagery training to improve language processing: What are the arguments?

Sylvain Jean-François Harquel

Studies showed that motor expertise was found to induce improvement in language processing. Grounded and situated approaches attributed this effect to an underlying automatic simulation of the motor experience elicited by action words, similar to motor ima ...

Multi-scale and cross-dimensional TMS mapping: A proof of principle in patients with Parkinson's disease and deep brain stimulation

Estelle Emeline Raffin, Sylvain Jean-François Harquel

IntroductionTranscranial magnetic stimulation (TMS) mapping has become a critical tool for exploratory studies of the human corticomotor (M1) organization. Here, we propose to gather existing cutting-edge TMS-EMG and TMS-EEG approaches into a combined mult ...
