Study Summary
This study investigates the neural mechanisms causally involved in how people navigate through their immediately visible environment (e.g., walking around one's bedroom flawlessly and effortlessly, not bumping into the walls or furniture). To investigate whether particular neural mechanisms are causally involved in "visually-guided navigation", repetitive transcranial magnetic stimulation (rTMS) is used to temporarily disrupt the functioning of particular brain regions in healthy adults while they are shown simple visual stimuli of places (e.g., bedrooms, kitchens, and living rooms) and asked to perform simple computer tasks or to complete simple behavioral tasks.
Primary Outcome
To assess performance during the visually-guided navigation computer-based task, rTMS is applied to to the control vertex site, which is not implicated in visually-guided navigation, as well as the occipital place area (OPA) site. While participants are shown simple visual stimuli of places (e.g., bedrooms, kitchens, and living rooms) they are asked to perform simple computer-based tasks (e.g., imagine they are walking through the room, and respond via button press whether they can leave through
