SOME CONTEMPLATIONS ON THE ROLE OF THE GLOBUS PALLIDUS IN PARKINSONISM

　We reported last year that two main　symptoms of Parkinsonism, namely, rigi-dity and tremor, could be markedly impro-ved by the Procaine-Oil blocking of the　globus pallidus．　This procedure is a part　of our stereotaxic operation on the globus　pallidus for the treatment of the hyper-kinetic disorders, the summarizing report　of which will be communicated in Acta　Psychiatria et Neurologia Japonica．　Thetotal number of the operated cases for　Parkinsonism is, at present, thirty-five．　In　this short paper, we will try to suggest　some interpretation on the relationship of　the globus pallidus to muscular rigidity in　Parkinsonism．

　It is the opinion of these authors that　there is a little doubt as to the correctness　of the prevailing theories on the function　of the globus pallidus in hyperkinetic mo-vement, especially as seen in the Parkin-sonian tremor．　It goes without sayingthat we do not expect to reach a final　conclusion or formulate a new theory of　our own on this problem, but we do　expect to suggest certain new concepts　based on our studies which may be　helpful as a basis for further investiga-tion．
