A study led by Estelle Raffin and Michele Bevilacqua at the Neuro-X Institute investigated the effects of a novel brain stimulation protocol on 16 chronic stroke patients with homonymous hemianopia. The protocol involved cross-frequency transcranial alternating current stimulation (cf-tACS) targeting the primary visual cortex (V1) and the motion-sensitive area (MT). Results showed significant improvements in motion discrimination and visual field boundaries, particularly with forward cf-tACS, after just 10 training sessions, suggesting a faster rate of recovery compared to traditional methods.
1. Study on chronic stroke patients with visual field deficits. 2. Used cross-frequency tACS over the visual cortex. 3. Significant improvement in motion discrimination observed. 4. Forward cf-tACS showed better results than backward cf-tACS. 5. Kinetic and static perimetry indicated enhanced visual sensitivity. 6. Findings suggest quicker recovery rates compared to traditional methods. 7. Structural connectivity analyzed using diffusion-weighted imaging. 8. Registered clinical trial (NCT05220449) confirms ethical compliance.
