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 ...

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 ...

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 ...

A Novel Patient-Tailored, Cumulative Neurotechnology-Based Therapy for Upper-Limb Rehabilitation in Severely Impaired Chronic Stroke Patients: The AVANCER Study Protocol

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

Effective, patient-tailored rehabilitation to restore upper-limb motor function in severely impaired stroke patients is still missing. If suitably combined and administered in a personalized fashion, neurotechnologies offer a large potential to assist reha ...

Enhancing visual motion discrimination by desynchronizing bifocal oscillatory activity

Friedhelm Christoph Hummel, Estelle Emeline Raffin, Roberto Felipe Salamanca Giron, Sarah Bernardina Zandvliet, Martin Seeber

Visual motion discrimination involves reciprocal interactions in the alpha band between the primary visual cortex (V1) and mediotemporal areas (V5/MT). We investigated whether modulating alpha phase synchronization using individualized multisite transcrani ...
