An ipsilateral vestibulo-thalamic tract in the medial lemniscus

Objectives: Information processing in the vestibular system is organized as a multilevel sensorimotor network to subserve postural, ocular motor and perceptual function. Unilateral damage of vestibular input to the cortex mainly results in pathological deviations of the perceived visual vertical. So far it is unclear, how vestibular input is transmitted from the vestibular nuclei to the cortex. A crossed graviceptive pathway within the MLF has been postulated, which has multisynaptic projections running via the integration centres for eye movements in the roll plane to the thalamus. An uncrossed graviceptive pat…
