Study on vomiting related to the vestibulo-autonomic reflex.

The purpose of this study was to investigate the neural pathway from the vestibular labyrinth to the medullary vomiting center in the cat, using electrophysiological techniques. During electrical stimulation of the canal nerve, we found conflicting results: the pressure in the stomach sometimes increased, and sometimes decreased. There might be several neural structures between the semicircular canal nerve and the vomiting center in the dorsolateral portion of the reticular formation of medulla oblongata. Retching or vomiting-like behavior during both respiration and movement of the stomach was recorded during stimulation at several sites in the lateral medullary reticular formation. However, the evoked unit activities were not always induced by stimulation of the canal nerve.

Vestibular training for benign paroxysmal positional vertigo. Its efficacy in comparison with antivertigo drugs.

A modified controlled study on treatment effects of vestibular training (VT) for benign paroxysmal positional vertigo was performed. The VT was compared with courses of patients in three different groups: patients treated by medication, by VT, and by VT with medication during 8 weeks. It was statistically confirmed by global judgments of symptoms and signs that improvement rates of positional nystagmus and vertigo were higher in the two groups treated by VT with and without medication than the improvement rate in the medication alone group. In the groups treated by VT, the effects were not influenced by time since onset of disease or by patient age. It is therefore assumed that VT can be used as a first-choice treatment in patients with benign paroxysmal positional vertigo, even in long-term cases or older patients.
