Encoding the position of a flashed visual target after passive body rotations

The capacity of the central nervous system (CNS) for processing vestibular signals during passive whole-body rotations to update the internal representation of a visual target position in relation to the body was assessed.

Summary:The capacity of the central nervous system (CNS) for processing vestibular signals during passive whole-body rotations to update the internal representation of a visual target position in relation to the body was assessed. Results showed that subjects mislocalized previously presented visual targets after body rotations in complete darkness. Detailed analysis of the results suggested that the large target mislocalization stemmed not only from a systematic underestimation of rotation magnitude but also from the incapacity of the CNS to use the vestibular signals to accurately update the internal representation of the target position in relation to the body after passive rotations.
