Abstract
The intermittent, intercalated and adaptational types of stimulation were administered to the efferent or afferent nerves, and the muscle tension of a frog [Rana catesbeiana and R. nigromaculata] nerve-muscle or spinal reflex preparations was recorded. Enhancement of tension was observed when the appropriate intermittent or intercalated stimulation was applied. In the nerve-muscle preparation, this effect was made clearly detectable when the nerve-muscle preparation was equilibrated with Ca2+-deficient Ringer solution. An appropriate type of adaptational stimulation evoked a rapid and long-lasting tension development which may be of physiological meaning in an emergency.
