The Effect of Transcranial Direct Current Stimulation on Visual Attention - Single Sessions

Cognitive Decline Clinical Trial

Official title: The Effect of Transcranial Direct Current Stimulation on Visual Attention - a Combined MRI and Non-invasive Brain Stimulation Single Session Study

Status Completed

Clinical Trial Summary

Recently, attention has been drawn to non-invasive brain stimulation techniques, such as transcranial direct current stimulation (tDCS), in order to enhance cognitive functions by modifying brain plasticity and use it in different healthy and diseased populations. In the current research, investigator aim to examine the short-term effects of multiple tDCS protocols in healthy adults population on visual attention and identify the neural underpinnings of tDCS-induced behavioral aftereffects using a combined tDCS/ MRI network-based approach.

Clinical Trial Description

Investigator will investigate the shor-term effects of active tDCS as compared to a placebo stimulation on visual attention in the healthy seniors. A cross-over, randomized, placebo-controlled design will be used. Single tDCS sessions will be performed in 4 sessions over distinct brain areas with ongoing visual attention training. During the stimulation, investigator will use the visual matching task. MRI protocol consisting of T1 and resting state fMRI sequences will be acquired before and after every stimulation session in order to search for active vs. placebo tDCS-induced changes in brain activation and resting state functional connectivity and to identify neural correlates of behavioral changes. ;
