The project will consist of 3 Work Packages (WPs):~The aim of WP1 is to map the relationship between GS and clinical outcomes with EEG.~The aim of WP2 is to translate GS assessment and modulation to bedside.~The aim of WP3 is to modulate GS to improve rehabilitation outcomes.
In the last decades, the research in neuroimaging-informed stroke prognosis and treatment has had a little clinical impact, often because of the costs of bringing complex procedures to the bedside. Cerebral stroke remains the leading cause of disability, with 65% of survivors chronically impaired at 6 months. Gamma synchrony (GS) is a fundamental mechanism of cortical function and can be estimated and modulated in a simple, inexpensive, and reliable way. It has provided valuable and cost-effective guidance in several neuropsychiatric conditions. In previous studies, we developed simple yet robust methods for assessing and manipulating GS and proved its relationship with clinical impairment in preliminary data.~The aim of the present project is to predict and improve stroke recovery by leveraging cortical mapping and modulation of GS via transcranial alternating current stimulation (tACS), a safe and inexpensive technique. The project capitalizes on technology readily available to the Italian national health system.
