[Status of the spinal inhibitory reactions in humans subjected to hyperbaric oxygenation].
The state of human spinal inhibition responses under normo- and hyperbaric pressure (6.5 ata) was comparatively studied. The paired stimulation method has been used to estimate resetting of tested monosynaptic reflex in the 20-900 ms interval of paired stimulation at rest or against the background of supraspinal modulation of spinal reflective processes (Jendrassik manoeuvre, voluntary plantar flexion) were studied. The depression of inhibition reactions under hyperbaric pressure identical to that during the supraspinal modulation under normobaric conditions is shown. It is supposed that these influences on spinal reflection processes are caused by the same neuronal mechanism.
