Brain Stimulation and Impulsive Eating


Researchers at the University of Calgary Mathison Centre for Mental Health Research and Education are interested in using brain stimulation as a way of impacting food related impulsivity.

We are using a non-invasive brain stimulation technique called transcranial direct current stimulation and simple computerized tests. This study involves a single visit lasting approximately 3 hours.

Participants will receive a $15 gift card and be reimbursed for parking expenses for completion of the study.
