After a preliminary partial removal of the cerebral hemisphere on one side and subsequent degeneration of the fibers originating therefrom, the exposed corpus callosum becomes available for pure antidromic stimulation. In the rabbit motor cortex, with monopolar surface leading, the response elicited by a single antidromic volley from the corpus callosum, has a rather regular pattern with minor variations. The first phase is uniformly simple, while the second negative phase with its various modifications generally shows the presence of more or less prolonged negativity which does not seem to be accountable for by antidromic activation of the callosal neurons alone. The second negative phase becomes relatively much more conspicuous with the stronger stimuli and is generally accompanied by discharges in the pyramidal tract. This part of the response is greatly increased by strychnine. It is thus clear that antidromic stimulation of the callosal neurons through their collaterals can initiate postsynaptic activities. With 2 strong stimuli at increasing intervals, the response to the second stimulus still shows a peculiar deficit in its second phase even at intervals of over 200 msec. With 2 weaker stimuli in succession, however, the second phase of the response to the second stimulus may show a relative increase in size instead of a relative deficit. The cortical responses to antidromic stimulation of the corpus callosum and of the pyramidal tract, when they follow each other in close succession, have been found to show considerable mutual interaction. The interaction between the response to antidromic caUosal stimulation and the initial negative response to direct surface stimulation has also been observed. In their sensitivity to local surface application of procaine, the various components of the cortical response to pure antidromic and to mixed antidromic and orthodromic callosal stimulation show characteristic differences. Recording with microelectrode shows that the second negative phase of the cortical response to antidromic callosal stimulation becomes progressively displaced forward in time. while the initial positive phase becomes smaller and smaller as the microelectrode is lowered step by step, until at a depth of about 1.2 mm, the initial positive phase disappears altogether. All these could be understood by reference to cortical histology.

摘除一侧大腦半球的一部分,等待足够時日使發源於這一部分大腦皮層的胼胝體纖維變質,然後刺激暴露出來的胼胝體就可以得到純粹的逆行衝動傳向對側大腦皮層的胼胝體神經原。用單極引出,這種逆行衝動在大腦皮層引起的反應首先是一個簡單的正電位,然後是一個時程較長的負電位。這負電位可被番木龞鹼大大增加,並伴有錐體束放射。這些表明,胼胝體神經原在接受逆行刺激時能通過其側枝引起突觸後的活動。在用接連兩次逆行刺激時,隨着所用刺激是弱或強,第一個反應的負電位部分可以增大或減小。由胼胝體的逆行刺激和錐體束的逆行刺激在皮層所引起的兩個反應之間有相互影響,當後者在先時,前者的負電位部分減少。就局部施加於大腦皮層表面的普魯卡因溶液對於它們的藥效發展的快慢而言,胼胝體逆行刺激在皮層引起的反應與胼胝體的順行及逆行混合刺激所引起的反應的各組成部分有其特異的差別。用微電極逐步插入皮層不同深度處記錄得到的胼胝體逆行刺激所引起的反應表現有系統的變化。這些結果從有關組織學資料可以得出自然的解釋。

The effects of repetitive cortical stimulation on the evoked potential have been investigated in encépale isolé preparations of cats and in rabbits anesthetized with a mixture of 1% chloralose and 10% urethane solution.The evoked potentials were recorded from the visual or auditory area of the cerebral cortex by an eight-channel electroencephalograph.Repetitive electric stimulation for three seconds was applied to a cortical point close to one of an array of the recording electrodes.Either depression or potentiation of the evoked potentials could be produced,depending on the depth of anesthesia and the stimulus parameters selected. (1)The spreading depression.On strong stimulation the evoked potential,after a latent period of half a minute,was severely depressed for about two minutes and then began to recover.Before finally returning to the original magnitude the potentials might surpass the control size.The total recovery time lasted for about thirty minutes.The degree of the augmentation of the potential seemed to depend on the level of anesthesia.Changes in stimulus intensity and in depth of anes- thesia,however,showed no effect on the process of depression.The depression propagated in all directions of the cortex at a speed of 2—8 mm per minute.No interhemispheric propagation was manifested.The initiation of the depression wave could be prevented by local application of 10% procaine solution at the stimulating electrodes. (2)The poientiation effect.Under certain conditions,the evoked potential could be greatly potentiated immediately after repetitive electric stimulation.Potentiation seemed to be confined only o the vicinity of the point stimulated and lasted for no more than forty seconds.A prerequisite for the production of the effect of potentiation was the proper frequency of stimuli;the anesthesia,the intensity and the duration of the stimulating pulse were contributory factors. Since the potentiation or depression could be induced separately by appropriate treatment of the preparation and by proper selection of stimulus parameters,it is assumed that the mechanisms un- derlying the two effects are independent of each other.

实验在家兔(用氯醛糖和氨基甲酸乙酯混合液麻醉)和猫(施行“隔离脑”手术)身上进行。用多点记录法在动物皮层的视区或听区引出诱发电位后,即在某一记录点附近给以3秒钟的重复弱电流刺激,可以观察到两种不同的效应:(一)阻抑作用:始于刺激后的半分钟左右,诱发电位迅即被完全阻抑,2至3分钟后电位渐渐增大,并增大到超出刺激前的水平,以后才逐渐恢复正常。全部阻抑过程历时约30分钟。改变刺激强度或麻醉深度对阻抑作用的影响不大。阻抑以每秒2—8毫米的速度向四周扩散,但不向对侧皮层扩散。皮层局部用10%普鲁卡因涂敷后,电刺激就不能引起阻抑扩散。 (二)强化作用:在适当的刺激条件下,刺激后立即出现诱发电位的强化现象,其时程不超出40秒,以后紧随着就出现电位的阻抑作用。越接近刺激点,强化的效应就越大,但强化不向四周扩散。强化作用的出现主要取决于刺激的频率,其他如麻醉深度、刺激波宽和强度等都具有一定的影响。利用巴比妥钠和10%普鲁卡因可以使诱发电位的强化和阻抑现象分别地表现出来。由此推论,强化作用和扩散性阻抑的发生机制是不相同的。

A train of repetitive shocks applied to one side of the cerebral cortex in unanesthetized rabbit normally elicited a train of electrical responses of more or less regular amplitude in the contralateral cortex.After sectioning of the corpus callosum,the responses changed to a new one composed mainly of surface negative waves and charac- terized by periodic waxing and waning of the amplitude of the responses to individual shocks.Such responses could be obtained from the sensori-motor cortex as well as from the...

A train of repetitive shocks applied to one side of the cerebral cortex in unanesthetized rabbit normally elicited a train of electrical responses of more or less regular amplitude in the contralateral cortex.After sectioning of the corpus callosum,the responses changed to a new one composed mainly of surface negative waves and charac- terized by periodic waxing and waning of the amplitude of the responses to individual shocks.Such responses could be obtained from the sensori-motor cortex as well as from the visual cortex.Further transection of the thalamus along the midline abolished such responses.Electrical responses could also be recorded from the central portion of the thalamus but with amplitude showing no waxing and waning phenomenon.The res- ponses described above from the cortex and the thalamus could be degressed by stimula- tion of the divided corpus callosum on the recording side.It is assumed that stimulation of the cerebral cortex may activate the central portion of the thalamus which in turn activates the contralateral cortex.The nerve impulse passing through the corpus callosum may have a depressive action on such thalamically involved responses.

在切断胼胝体以后,用低频重复刺激直接刺激大脑皮层,在几个刺激以后,每个刺激都会在对侧皮层引起一个以表面负电位为主的反应,其振幅呈周期性的起伏。将丘脑沿中线切开后,这种反应消失不见。从皮层得到这种反应时,将电极插在丘脑近中央部分记录,也能在每个刺激后引出清楚的反应。来自胼胝体的冲动对这种反应有压抑作用。
