[Study of postinhibitory "rebound" in individual motor units of human hand muscles].
Analysis of poststimulus histograms and interspike intervals of firing motor units showed that the burst following the silent period under evoked muscle contraction is the result of synchronous motoneuron escape from inhibition. Under strong evoked isotonic muscle contraction a true facilitation was revealed. The latency of this facilitation was too long for spinal monosynaptic reflex related to spindles elongation at the muscle relaxation stage.
