条件反射的形成是由於无关动因与非条件反射的一定结合,就其神经机制而言,则是由于在大脑皮层中两个兴奋灶之间的神经接通,结果无关动因获得了一定的生理意义,可引起动物机体的某些积极反应,例如运动性与分泌性反应。此类条件反射称为阳性条件反射,是由于兴奋过程在大脑皮层中活动的结果。 The formation of conditioned reflex is due to the combination of irrelevant and nonconditional reflexes. In terms of the neural mechanism, it is due to the fact that the nerve between the two excitatory foci in the cerebral cortex is connected and the result has nothing to do with the physiological meaning , Can cause some positive reactions in the body of the animal, such as motor and secretory responses. This type of conditioned reflex, known as a positive conditioned reflex, is the result of the activity of the excitement in the cerebral cortex.
