要完全理解神经回路，不仅要知道它们是如何工作的，还要知道它们为什么这样工作。对后一个问题的回答在他们的最优设计假设中几乎是目的论的。然而，对某些系统的仔细检查揭示了明显缺乏适应价值的特征。只有考虑到这些回路的进化，特别是非适应性决定因素是如何引导这种进化的，才能理解它们的存在。
To understand neural circuits completely, it is necessary to know not only how they work, but also why they work that way. Answers to the latter question have been almost teleological in their assumption of optimal design. However, close examination of certain systems has revealed features that apparently lack adaptive value. Their existence can be understood only if the evolution of these circuits is considered and, in particular, how nonadaptive determinants have guided that evolution.
