It was found by the authors that in cases where 1% procaine solution was injected into nape muscles in normal subjects, vertiginous attacks as indicated by a sensation of sway of the body and "blacking out" were observed, accompanying with nausea and vomiting. The phenomenon mentioned above was evidently presented in case of applying the solution to deep nape muscles such as M. rectus capitis dorsalis major et minor, M. obliques atlantis and M. transversoocclpltalls. Whereas when the same procedure was carried out in superficial nape muscles such as M. trapezius and M. splenius, no sign of demonstrable disequilibrium nor any of disturbances of the vegetative reactions was observed. As to M. sternocleidomastoideus, it should be stressed here that when the procaine solution was applied to the muscle on one side and in a specific portion, i. e, in the origin of the muscle, the disequilibrium previously described was often observed, but it was not so marked as that in the case of deep nape muscles.By employing "Active head rotation test" devised by the authors as well as Romberg test, the authors were able to demonstrate the vertiginous attacks in the cases at hand as incoordination of the eye and head movements in case of active head rotation and a positive Romberg sign respectively.It is quite possible to say that the phenomenon mentioned above is considered to be caused on account of suddenly occured disturbances in the central nervous system, especially in the brain stem, which would be caused by ablation of impluses originating from y system in the muscles previously described, and that according to the investigations hitherto described, the ablation of impluses mentioned above should be presented by the injection of procaine solution mentioned.
