Title: Rapid gaze-shift adaptation during self-generated vestibular prosthetic stimulation

The brain must differentiate between externally-generated and self-generated sensory inputs to build stable perception and generate appropriate behavior. Despite recent advances in neuroprostheses, little is known about how the brain interprets prosthetic sensory input, especially when self-generated. For vestibular prosthesis users, the brain must learn to utilize prosthetic vestibular input to maintain visual and postural stability while also suppressing/canceling these reflexes when they are counterproductive to behavioral goals. We leveraged a gaze-shift task—a naturalistic behavior that requires the cancellation of vestibular input—to directly investigate how self-generated prosthetic stimulation affects reorientation behaviors.
