一、擴散1)興奮過程的擴散在神經系統生理学中很早就已经知道這樣一個事實:在腦神經系統內發生的神經活動過程(指興奮或抑制——譯註),能够從它發生的地方向外擴延。向外擴延的範围是由發生的興奮的强度和脑神經系統的機能狀態這兩方面來决定的。這种現象叫做興奮過程的擴散。同樣的扩散也發生在大脑皮质內。譬如说,如果用每分鐘振動120次的拍節机敲擊聲形成條件反射,脑皮質的聽區,由於興奮向外擴散的結果,就不僅對每分钟振動120次拍節机的敲擊聲,而且對於比120
First, the proliferation of 1) the proliferation of excitement in the neurophysiology of physiology has long been known about the fact that the nervous system in the nervous system within the process of activity (refers to the excitement or inhibition), from where it can occur to Outreach. The extent of outreach is determined by both the intensity of excitement that occurs and the functioning of the brain’s nervous system. This phenomenon is called the proliferation of excitement. The same spread occurs in the cerebral cortex. For example, if the percussion beat percussion beat percussion 120 times to form conditioned reflex, auditory cortex, as a result of excitement spread out, not only for every 120 times the percussion beat machine percussion , But also for a ratio of 120
