Magnetic Resonance Imaging (MRI) and Electroencephalography (EEG): Those who qualify will be asked to undergo two brain scans using Magnetic Resonance Imaging (MRI). The MRI scans will be used to obtain high quality structural images of your brain, as well as examine how your brain performs during a visual task using functional MRI. During the functional MRI, your brain activity during a visual task will also be measured using EEG. For the EEG, you will be wearing an electrode cap (see image). These electrodes are able to measure activity in different parts of your brain that allow us to see how your brain is performing. There are no known health risks associated with EEG.
The MRI scan is not associated with any known risks to your health and there is no evidence that there will be either short-term or long-term side effects. Prior to the studies you will be required to fill out a questionnaire to ensure that there are no contraindications for participating. The only absolute requirements for the MRI scan are that you do NOT have an implanted cardiac pacemaker and that you do NOT have any magnetic metal implants, pieces of shrapnel, or wires in any part of your body. If you cannot participate in the MRI portion of the study, you will still be able to compete the EEG testing outside of the MRI scanner.
This MRI scan is not a substitute for one that a doctor would order, and it may not show problems that would be picked up by a medical MRI scan. Should we note an atypical finding on your MRI scan, we will contact you to help you arrange medical follow-up to interpret the significance of the findings, if any.
