TY - JOUR T1 - Adaptive plasticity in the spinal stretch reflex. JF - Brain research Y1 - 1983 A1 - Jonathan Wolpaw A1 - Kieffer, V. A. A1 - Seegal, R. F. A1 - Braitman, D. J. A1 - Sanders, M. G. KW - Learning KW - Memory KW - plasticity KW - primate KW - spinal reflex KW - stretch reflex AB - Monkeys can change the amplitude of the spinal stretch reflex without change in initial alpha motor neuron tone, as measured by EMG, or in initial muscle length. Change is apparent in 5-10 days, continues to develop over weeks, and persists during inactive periods. Spinal stretch reflex change may be a valuable system for studying the neuronal and synaptic bases of an adaptive change in primate CNS function.
