-
5
Kinetic and static perimetry indicated enhanced visual sensitivity.
-
6
Findings suggest quicker recovery rates compared to traditional methods.
-
7

8
Registered clinical trial (NCT05220449) confirms ethical compliance.
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.
