Pathway-dependent Brain Stimulation Responses Indicate Motion Processing Integrity After Stroke

Friedhelm Christoph Hummel, Elena Beanato, Estelle Emeline Raffin, Lisa Aïcha Mireille Julie Fleury, Fabienne Windel, Michele Bevilacqua, Sarah Bernardina Zandvliet, Pauline Menoud

Homonymous hemianopia (HH), a common visual impairment resulting from occipital lobe lesions, affects a significant number of stroke survivors. Intensive perceptual training can foster recovery, possibly by enhancing surviving visual pathways. This study e ...

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 ...

Probing and modulating inter-areal coupling in the cortical visual motion processing pathway with non-invasive brain stimulation

Michele Bevilacqua

In the last few years, stroke ranked as the second most common cause of death and is the third most significant condition affecting disability-adjusted life years (DALYs) worldwide. Being the most prevalent and quality of life impacting post-stroke symptom ...

Single session cross-frequency bifocal tACS modulates visual motion network activity in young healthy population and stroke patients

Friedhelm Christoph Hummel, Estelle Emeline Raffin, Lisa Aïcha Mireille Julie Fleury, Fabienne Windel, Michele Bevilacqua, Roberto Felipe Salamanca Giron, Sarah Bernardina Zandvliet, Pauline Menoud

Objective: This study investigates the impact of single-session, cross-frequency (Alpha-Gamma) bifocal transcranial alternating current stimulation (cf-tACS) to the cortical visual motion network on inter-areal coupling between the primary visual cortex (V ...

Pathway and directional specificity of Hebbian plasticity in the cortical visual motion processing network

Friedhelm Christoph Hummel, Estelle Emeline Raffin, Michele Bevilacqua

Cortico-cortical paired associative stimulation (ccPAS), which repeatedly pairs single-pulse transcranial magnetic stimulation (TMS) over two distant brain regions, is thought to modulate synaptic plasticity. We explored its spatial selectivity (pathway an ...

On Error-Related Potentials During Sensorimotor-Based Brain-Computer Interface: Explorations With a Pseudo-Online Brain-Controlled Speller

Michele Bevilacqua

Objective: Brain-computer interface (BCI) spelling is a promising communication solution for people in paralysis. Currently, BCIs suffer from imperfect decoding accuracy which calls for methods to handle spelling mistakes. Detecting error-related potential ...

Design and validation of a foldable and photovoltaic wide-field epiretinal prosthesis

Diego Ghezzi, Laura Ferlauto, Kevin Sivula, Naïg Aurelia Ludmilla Chenais, Samuel Charles Antoine Gilliéron, Marta Jole Ildelfonsa Airaghi Leccardi, Paola Vagni, Michele Bevilacqua

Retinal prostheses have been developed to fight blindness in people affected by outer retinal layer dystrophies. To date, few hundred patients have received a retinal implant. Inspired by intraocular lenses, we have designed a foldable and photovoltaic wid ...
