The investigators will perform a double blind, randomized, sham controlled, crossover study design to assess effects of tES, tsDCS and sham stimulation on the performance during a cognitive control task. The working Hypothesis is tsDCS and/or tES will enhance frontal theta oscillations as recorded on EEGs and improve task performance compared to sham stimulation.~Results from this project can potentially lead to the development of a new research tool for assessing neuromodulation strategies to treat mental disorders and their comorbidities. It will also uncover the neural correlates of cognitive deficits in PSD and provide feasible biomarkers associated with treatment response in support of a larger clinical.
This study aims to investigate effects of transcranial current stimulation (tES) and transcutaneous direct current stimulation (tsDCS) associated changes on fronto-parietal EEG and cognitive performance in patients with post stroke depression (PSD)
