从理论上分析了可修改的突触。证明了它们可分为三类（称为A、B和C），使得同一类的任何两个成员，借助于执行简单逻辑运算的非记忆元素，在任何网中都可以相互替换;但A类的成员不能替换B或C类的成员。只有当网络中包括非逻辑元件（例如噪声发生器）时，B类的成员才能替换A类或C类中的一个。模型的设计，使用可修改的突触，并显示经典和操作性条件反射的主要特征。如果模型被赋予灭绝的性质，经典条件作用需要A类和B类或C类的可修改突触，以及B类或C类的操作性条件作用。有人认为，如果神经系统的条件反射和记忆机制是通过可改变的突触来存储信息的，那么其中的一些突触一定是B类或C类突触。
Modifiable synapses are analysed theoretically. It is proved that they fall into three classes (called A, B and C), such that any two members of the same class can, with the aid of non-remembering elements that perform simple logical operations, replace one another in any net; but a member of class A cannot replace one of class B or C. A member of class B can replace one of class A or C only if non-logical elements, for example noise generators, are included in the net. Models are designed that use modifiable synapses and show the principal features of classical and operant conditioning. If the models are to be given the property of extinction, classical conditioning requires modifiable synapses of classes A and B or of class C, and operant conditioning of class B or C. It is argued that if the conditioning and memory mechanisms of the nervous system store information by means of modifiable synapses, some of these must be of class B or C.
