Visual-Vestibular Integration Dysfunction

SKU: C06024

This exhibit shows the process of visual-vestibular integration dysfunction. Cervical spinal cord compression damages ascending nerve signals, and the abnormal vestibular signals pass to the vestibular nucleus. Abnormal input to the abducent nucleus causes abnormal motor signals to be passed on to the lateral rectus eye muscle and then continue through the midbrain to the medial longitudinal fasciculus. Abnormal input to the trochlear nucleus causes abnormal motor signals to be passed to the superior oblique eye muscle. Abnormal input to the oculomotor nucleus causes abnormal motor signals to pass to the remaining eye and pupillary muscles. Abnormal visual-vestibular signals are passed to the brain, where they cannot be clearly interpreted.
