INTERVENTIONAL
Conditions
Summary
The CERSTIM study is a physiopatholgical study investigating transcranial alternating current stimulation in stroke patients in the cerebello-motor loop. The design is a cross over design testing two frequencies in the gamma band and one placebo. We will use behavioural data, functional MRI, and Electroencephalography to disentangle the effect of tACS and its frequency. Healthy participants will be also recruited.
