Zaporozhe State Medical University, Ministry of Public Health of Ukraine, Ukraine aut Interaction between the Postactivation Depression of H Reflex and Long-Lasting Inhibition, Evoked by Stimulation of a Nerve to the Antagonist Muscles, in Humans [Elektronische Daten] [V. Rudneva] In a study on healthy humans, we examined interaction of the inhibitory influences on the H reflex recorded from the m. soleus (the respective EMG discharge, evoked by stimulation of the n. tibialis comm.). Postactivation depression of the reflex was evoked by a preceding conditioning stimulation of the same nerve, while conditioning stimulation of a nerve to the antagonist muscles (n. peroneus comm.) evoked long-lasting inhibition of the reflex, which included two consecutive waves of depression, D 1 and D 2. When the intensity of conditioning stimulations slightly exceeded the threshold for the development of inhibitory effects, interaction between postactivation depression and both the D 1 and D 2 waves demonstrated mutual facilitation of these effects. When the intensity of conditioning stimuli was increased, facilitation was changed by occlusion. We conclude that afferent impulsation, evoked by homo- and heteronymous conditioning stimulations of the peripheral nerves, converges on common interneuronal populations providing long-lasting suppression of the H reflex, which develops due to depolarization of primary afferent Ia terminals.
