With them it has been demonstrated that: (1) Myanesin decreases or abolishes facilitation and inhibition reaching anterior horn cells from all levels of the C.N.S. (2) Neural circuits containing internuncial cells are vulnerable to Myanesin, whereas "direct" circuits withstand large doses without effect. (3) Relief of spasticity by Myanesin can be explained in terms of these effects. (4) The site of action of Myanesin is probably the internuncial cell. 1949 by The American Society for Pharmacology and Experimental Therapeutics
