Effects of non-invasive brain stimulation on reward-guided decision making in adults with low mood

Researchers at the Department of Psychiatry, University of Oxford are seeking volunteers with low mood aged 18 – 45 years for a transcranial Direct Current Stimulation (tDCS) study.

The purpose of this study is to examine how the brain processes information and enables us to make decisions. The results will guide our future research aimed at helping individuals who suffer from depression.

Transcranial Direct Current Stimulation is a form of neurostimulation that uses constant, low current delivered to the brain via sensors on the scalp. Participants may experience some mild temporary discomfort during tDCS. By using this technique, we hope to find out how different brain regions contribute to making decisions.

This study involves one video call and 2 visits to the Oxford Centre for Human Brain Activity at the Department of Psychiatry at the University of Oxford. Each session will take no more than 2 hours.

Volunteers will be reimbursed for their time and can win additional money depending on task performance.

All study procedures have been adapted to minimise risks from transmission of COVID- 19, in line with NHS and University safety guidance.

If you are interested in participating in this study and/or would like further information, please contact Verena Sarrazin at
