Recent studies suggest that none of the behaviors of the vertebrate CNS are fixed responses incapable of change. Even the simplest reflex of all, the two-neuron, monosynaptic spinal stretch reflex (SSR), undergoes adaptive change under appropriate circumstances. Operantly conditioned SSR change occurs gradually over days and weeks and is associated with a complex pattern of CNS plasticity at both spinal and supraspinal sites.
最近的研究表明，脊椎动物中枢神经系统的行为都不是固定不变、无法改变的反应。即使是所有反射中最简单的双神经元单突触脊髓牵张反射（SSR），在适当情况下也会发生适应性变化。操作性条件反射引起的SSR变化会在数天和数周内逐渐发生，并且与脊髓和脊髓上部位的中枢神经系统可塑性的复杂模式相关。
