Study participation

Visual Perception Study

We are interested in understanding basic functions of the human cerebral cortex using transcranial magnetic stimulation (TMS), combined with either electrophysiology (EEG) or optical imaging. TMS is a technique that uses strong magnetic fields to briefly interfere with neural activity in the brain. In our study, participants will perform simple visual tasks on a computer while TMS is administered and their brain activity is measured using EEG or optical imaging.

Interested participants should be right-handed native English speakers. Participation in this research will involve one or more separate sessions, each lasting no more than four hours. Participation is safe, voluntary and confidential. Participants will be paid $15/hour for their time.

This research is approved by the Institutional Review Board of the University of Illinois.
