At interval of less than 100 ms between indifferent sound and unconditioned electrocutaneous stimulation, classical defensive conditioned reflex is not elaborated in dogs, in full correspondence with literature data. But intracortical temporary connection is established; this fact is shown by electrographic phenomena, the most specific and demonstrative among them is "conditioned evoked potential". The absence of behavioural (peripheral) and presence of electrographic (central) manifestations allow to assume that for the formation of the conditioned reflex of full value the involvement is necessary of additional activational (motivational) mechanisms, connected with reticular and (or) limbic subcortical structures which do not react to the conditioned stimulus at time deficit in conditions of microdelay.
在无关声音与非条件性皮肤电刺激之间的间隔时间少于100毫秒时，狗不会形成经典防御性条件反射，这与文献数据完全相符。但皮质内暂时联系已经建立；这一事实通过电图现象得以证明，其中最具特异性和说明性的是“条件性诱发电位”。行为（外周）表现缺失而电图（中枢）表现存在，这使得我们可以假定，要形成完整的条件反射，需要额外的激活（动机）机制参与，这些机制与网状和（或）边缘皮质下结构相关，在微延迟条件下时间不足时，这些结构对条件刺激没有反应。
