Reduced day-to-day variation accompanies adaptive plasticity in the primate spinal stretch reflex

Reduced day-to-day variation accompanies adaptive plasticity in the primate spinal stretch reflex

Monkeys can change the amplitude of the spinal stretch reflex (SSR), or Ml, when reward is made contingent on amplitude. The present study demonstrates that reduced SSR day-to-day variation accompanies such adaptive SSR change. This finding supports the assumption that initial, phase I, SSR change r...

Zusammenfassung:Monkeys can change the amplitude of the spinal stretch reflex (SSR), or Ml, when reward is made contingent on amplitude. The present study demonstrates that reduced SSR day-to-day variation accompanies such adaptive SSR change. This finding supports the assumption that initial, phase I, SSR change results from contingency-appropriate stabilization of tonic activity in relevant descending spinal cord pathways.
