Unilaterally blind Subjects will be exposed to visual-auditory stimulation
The over-arching objective is to evaluate the functional recovery of vision in hemianopic patients engaged with a multisensory training paradigm. Unilaterally blind participants will participate in weekly training sessions in which they are exposed to high-density spatiotemporally congruent and consistent visual-auditory stimulation. The participants will be tested on a battery of visual tasks probing different levels of function in different environments in a longitudinal study to track recovery.
multisensory rehabilitation paradigm
In initial ("training") sessions, subjects will be exposed (and respond) to spatiotemporally congruent pairs of visual-auditory stimuli presented within their blinded field, with occasional probes of unisensory visual stimuli on both sides of space. Once recovery of visual responsiveness in the contralesional field is observed, sessions will alternate between "training/testing" and "testing only" sessions in which performance on the visual battery will be re-assessed.
