Study Details
Moment-to-Moment Changes in Visual Sensitivity
(IRB#: IRB_00177167)
Sensitivity to visual stimuli (response to eye activity) varies depending on how the brain processes information. The purpose of this study is to learn what adds to moment-to-moment changes in the visual system. This system of the eye and brain allows people to see light. This study will track the movements of the eye and pupil to report and detect faint visual targets on a computer monitor. People in the study will have eye movement and pupillary fluctuations (change of pupil in the eye) tracked using an eye-tracking camera. Participants will sit in an office chair with their heads placed on a chin stand. Participants will then stare at a computer monitor without blinking eyes for 8 to 10-second intervals. Being in the study requires attending about a 1-hour in-person visit at the study clinic. Participants could be asked to return to complete more sessions, up to 6 in total.
