人们普遍认为，学习是由神经通路中调节学习行为的突触的效力改变引起的。支持这一信念，这弥漫在当前的生理和计算思维，特别是来自无脊椎动物的简单学习案例的分析。在这里，有证据表明，在这样一种情况下，习惯的小龙虾逃脱，学习是由于发病的紧张下行抑制比电路突触的内在抑郁症，它以前归因于。因此，改变的表现似乎至少与局部可塑性一样依赖于更高中心的事件。
Learning is widely thought to result from altered potency of synapses within the neural pathways that mediate the learned behavior. Support for this belief, which pervades current physiological and computational thinking, comes especially from the analysis of cases of simple learning in invertebrates. Here, evidence is presented that in one such case, habituation of crayfish escape, the learning is more due to onset of tonic descending inhibition than to the intrinsic depression of circuit synapses to which it was previously attributed. Thus, the altered performance seems to depend at least as much on events in higher centers as on local plasticity.
