Study: Probing the neural mechanisms of Decisions with combined Transcranial magnetic stimulation and Electrophysiological recordings

Researchers at the Department of Experimental Psychology, University of Oxford are seeking volunteers aged 18-40 for a for a combined Transcranial Magnetic Stimulation (TMS) and Electrophysiological (EEG) recordings study. 

The purpose of this study is to examine how the brain is organised, and how it processes information and performs skills such as thinking and motor planning. TMS is a technique that allows us to stimulate the brain by rapid switching of a magnetic field in a coil placed over the head. Participants may experience some discomfort during TMS. By using this technique, we hope to find out how different brain regions contribute to the decision making and learning.

This study involves two visits to the Department of Experimental Psychology in Oxford for the study sessions. Each entire session will take no more than 4 hours, but usually take less than 3 hours. If you are unfamiliar with the techniques then we also ask you to come for an additional “taster” session so that you know what the experience feels like.  For the TMS localization we will furthermore ask you for a brief visit of 20 minutes at the John Radcliffe Hospital for a structural magnetic resonance scan (MRI). Volunteers will be reimbursed for their time taken in all sessions. We are looking for participants between 18 and 40 years old, right handed with normal or corrected to normal vision, with no history fainting, or mental illness and no experience of, or family history of, epilepsy. As we need structural MRI scans from our participants, they cannot have any contraindications for MRI scanning. If you are interested in participating in this study and/or would like further information, please contact Alex Sel at We will be running the study until October 2017.
