(51,73,74) The site of action of one fragment, ORG 2766, appears to be in the vestibular nucleus
This loss was most extensive in the superior vestibular nucleus
, and least in the medial vestibular nucleus
The spinal vestibular nucleus
(SpVe), was analyzed by tracer and highlighted its connections to the spinal cord (Liang et al., 2015).
(5) In cat studies involving measurements of the field potential of the lateral vestibular nucleus
, the application of acetylcholine produces the same response as does stimulation of the vestibular nerve.
Since commissural interaction between the bilateral brainstem vestibular nuclei is critically important for the neural integration responsible for gaze-holding, the abnormal gaze-holding timeconstant could possibly be related to neuronal degeneration within the vestibular nucleus
(Lopez, Honrubia & Baloh, 1997).
First, following the development of a unilateral peripheral vestibular lesion, the level of spontaneous neural activity in the vestibular nucleus
is reduced; after a period of compensation, this level can retum to normal.(9) Therefore, it is possible to attribute the deviation in the visual vertical to the temporary vestibular imbalance experienced prior to compensation.
