title: [Modulation of the segmental reflex reactions during real locomotion in rats].
abstract: Studies of low- and high-threshold reflex reactions evoked by dorsal root stimulation in different phases of real locomotion (swimming) in rat were performed. The pronounced facilitation of low- and high-threshold muscle responses in the period of particular muscle activity and their extensive depression in the period coupled with antagonist muscle activity were revealed. The low-threshold stimulation did not change the temporal and amplitude parameters of locomotor movements, but high-threshold one influenced the amplitude and frequency of locomotor movements. The functional significance and possible mechanisms of modulation of the influence of peripheral afferents are discussed.
