[Resting potential and action potential of an individual frog muscle fiber during reciprocal inhibition].
In single muscle fibres of the frog m. tibialis anticus longus resting membrane potential and parameters of the action potential were studied in situ during rest and during the resiprocal inhibition of its spinal center. Development of the reciprocal inhibition increased the resting membrane potential, the amplitude of the action potential, but decreased the time course and latency of the action potential. The changes in functional properties of single muscle fibres seem to occur as the result of deprovation of central influences due to the reciprocal inhibition.
