A strong stimulus applied directly to the cerebral cortex of unanesthetized animal (cat and rabbit) may elicit a train of repetitive responses composed mainly of surface negative waves at a frequency of 10-20 per second. Such repetitive responses are relatively more conspicuous in sensorymotor cortex, where it may last for more than 2 seconds. The duration of each negative wave varies between 20-50 msec, and the amplitude may reach as high as 1 mV. When one of the negative waves was made to overlap in time with...

A strong stimulus applied directly to the cerebral cortex of unanesthetized animal (cat and rabbit) may elicit a train of repetitive responses composed mainly of surface negative waves at a frequency of 10-20 per second. Such repetitive responses are relatively more conspicuous in sensorymotor cortex, where it may last for more than 2 seconds. The duration of each negative wave varies between 20-50 msec, and the amplitude may reach as high as 1 mV. When one of the negative waves was made to overlap in time with the initial surface negative wave elicited by another stimulus, the latter suffered a decrease. When atropine or procaine was applied to the cortical surface, it was found that both of the surface negative waves were affected parallelly. As the initial surface negative wave is generally regarded as representing the activity of the apical dendrites of the pyramidal neurons, the negative waves of the repetitive responses are inferred as also representing the activity of the apical dendrites. Application of procaine to the cortical surface depressed the negative waves of the repetitive responses rapidly, though the total duration of the repetitive activity was not shortened. The repetitive responses were more easily set up when the tips of the stimulating electrodes were inserted 1 mm deep into the cortex than when they were just touching the cortical surface. Neither transection of the brain stem between inferior and superior colliculi nor removal of the thalamic sensory nuclei affected the production of the repetitive responses. Such responses, however, could be completely abolished by the removal. of the central portion of thalamus. Stimulation applied to this portion of thalamus could elicit responses in the cortex of a pattern similar to that elicited by cortical stimulation. Repetitive responses of same frequency as that recorded from the cortical surface could also be led from this portion of the thalamus after cortical stimulation. From the above experimental evidences, it appears that the generation of the repetitive responses under consideration involves the action of some closed circuit existing between the cerebral cortex and the central portion of the thalamus, and that the repetitive surface negative waves are due to periodic bombardment on the apical dendrites by nervous impulses coming from that circuit.

用较强的电刺激直接刺激不麻醉动物的大脑皮层,所引起的反应包含以一串频率为10—20次/秒的表面负电位为主的重复反应。这种重复反应在大脑皮层广大区域都可以得到,而以在体感觉运动区得到的最为显著。它可以持续2秒以上,每一个负电位的时程为20—50毫秒,振幅可以达到1毫伏特左右。当这些表面负电位的任一个和另一刺激引起的第一个表面负电位同时出现时,後者减小;在大脑皮层表面局部施加阿讬品或普鲁卡因溶液後,这两种负电位有平行的变化。由於第一个负电位主要是代表锥体神经原顶端树状突的活动,重复反应的表面负电位主要也是代表顶端树状突的活动。在大脑皮层表面局部施加普鲁卡因後,虽然重复反应表面负电位的振幅迅速减小,但是重复反应持续的时间并不缩短。为了引起重复反应,在皮层表面刺激所需的刺激强度比将刺激电极尖端插在座层深1毫米处刺激所需的大几倍。由此看来,重复反应不是发源於顶端树状突。将脑干在上、下叠体之间切断,或将丘脑的感觉核吸去,重复反应的出现不受影响,但是如果将丘脑中央部分吸去,重复反应就不再出现。刺激丘脑这一部分也会在大脑皮层引起图形相同的重复反应。从这些结果看来,重复反应的表面负电位是大脑皮层和丘脑中央部分之间的闭合线路被激...

Sustained nociceptive stimuli were applied to the hind limb of 8 monkeys (Macaca mulatta)in three ways:(1)fracturing the fibula;(2)applying a chemical irritant(ether extract of capsicum)to the sciatic nerve topically;(3)injecting hypertonic saline into the gas- trocnemius and its adjacent subcutaneous tissues.All these methods were found to be capable of producing,on the surface of the pinnae,small discrete spots tender to pressure.The topographical distribution of the spots was not regular;but,statistically,they...

Sustained nociceptive stimuli were applied to the hind limb of 8 monkeys (Macaca mulatta)in three ways:(1)fracturing the fibula;(2)applying a chemical irritant(ether extract of capsicum)to the sciatic nerve topically;(3)injecting hypertonic saline into the gas- trocnemius and its adjacent subcutaneous tissues.All these methods were found to be capable of producing,on the surface of the pinnae,small discrete spots tender to pressure.The topographical distribution of the spots was not regular;but,statistically,they often appeared near the tip of the triangular fossa and the antitragus of the pinna.They began to appear from 40 minutes to several hours after the noxious treatment,and persisted for a period from 3 days to a few months(7—10 days on average).Intravenous injection of drugs known to suppress the activity of the reticular forma- tion of the brain stem,such as chlorpromazine or nembutal,augmented the reaction to pressure and increased the number of spots.On the contrary,drugs,such as LSD_(25),amphetamine or adrenaline,which increase the excitability of the reticular formation,suppressed the reaction to pressure and decreased the number of spots.In other experiments,procaine solution was injected into the third ventricle of the brain;1—2 minutes after the injection the referred tender spots disap- peared and reappeared after 13—60 minutes.This fact suggests that the central mechanism con- cerned in the production of the referred tenderness involves neural structure or structures situated in the central portion of the rostral brain stem;and perhaps the mechanism is inhibited by impulses from the reticular formation,as indicated by the experiments of intravenous injection.

用以下三种方法在8只猴人工产生了牵涉性耳郭压痛点:(1)切断腓骨;(2)化学物质(辣椒的乙醚提取物)刺激坐骨神经;(3)下肢肌肉及皮下注射高渗盐水。压痛点可出现于耳郭各处,但比较集中于三角窝尖端及对耳屏附近。压痛点在损伤后40分钟至数小时出现,持续3天至数月(平均7—10天)。静脉注射药理学上认为对脑干网状结构有抑制性影响的药物(氯丙嗪及戊巴比妥)后,压痛点增多,压痛反应增强。注射对网状结构有兴奋性影响的药物(离麦角酸二乙胺、苯异丙胺或肾上腺素),效果相反。这暗示参与耳郭压痛现象的神经结构受来自网状结构的冲动的抑制。第三脑室注射普鲁卡因溶液可在1—2分钟内取消耳郭压痛点,至第13—60分钟又行恢复,表明参与牵涉性耳郭压痛反应的一个中枢环节在脑干前端的中央部分。

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。
