Vestibular Function in AMD: Verticality Perception

Cartoon of falling apple

To accurately perceive one’s own state and that of the surrounding environment, visual, vestibular and somatosensory inputs must be appropriately weighted and dynamically reweighted depending on the environment and task difficulty, as well as signal reliability (and availability). Aging is associated with an increase on visual dependence (a greater weighting of visual information). In this project we investigate how loss of visual information due to age-related macular degeneration (AMD) affects this reweighting process and if an increase in visual dependence may be maladaptive in AMD.
