Although qualitative variance among nerve energies was never rigidly disproved , the doctrine was generally abandoned in favor of the opposing view , namely , that nerve impulses are essentially homogeneous in quality and are transmitted as “ common currency “ throughout the nervous system 譯文:盡管在神經能量上存在著質的不同,這一點從來都沒有在嚴格的意義上被反對過,但是以上教條通常被拋棄掉,而轉向相反的觀點,即:神經沖動從根本上本質相同,而且被當作“一種普通流“在整個神經系統中傳播

Although qualitative variance among nerve energies was never rigidly disproved , the doctrine was generally abandoned in favor of the opposing view , namely , that nerve impulses are essentially homogeneous in quality and are transmitted as “ common currency “ throughout the nervous system 盡管在神經能量上存在著質的不同,這一點從來都沒有在嚴格的意義上被反對過,但是以上教條通常被拋棄掉,而轉向相反的觀點,即:神經沖動從根本上本質相同,而且被當作“一種普通流“在整個神經系統中傳播。

Sodium plays a number of vital roles in the human body , contributing to the metabolizing of protein and carbohydrates , the transmission of nerve impulses , muscle contraction , hormone regulation , consumption of oxygen by cells , control of urine production , thirst , and the production of liquids ( blood , saliva , tears , perspiration , gastric juices , and bile ) 鈉擔任人體維持生命所必需的角色,貢獻為蛋白質和碳水化合物的代謝、神經沖動傳輸、肌肉收縮,調節內分泌,細胞氧的消耗,控制尿的生成、乾渴,和液體(血液、唾液、眼淚、汗水、胃汁液和膽汁)的產生。

For example , outside the afferent nerve fiber in week nerve passes into sensory information centre , the instruction information that efferent nerve fiber issues centre spreads effect implement , convey with the form of nerve impulse , and the biology report that nerve impulse calls behavioral potential one kind namely changes , it is the mark of nerve excitement 例如,外周神經中的傳入神經纖維把感覺信息傳入中樞,傳出神經纖維把中樞發出的指令信息傳給效應器,都是以神經沖動的形式傳送的,而神經沖動就是一種稱為動作電位的生物電變化,是神經興奮的標志。

Although qualitative variance among nerve energies was never rigidly disproved , the doctrine was generally abandoned in favor of the opposing view , namely , that nerve impulses are essentially homogeneous in quality and are transmitted as “ common currency “ throughout the nervous system 雖然神經元之間的本質不一樣從來就沒有嚴厲的否定,教條卻一般放棄了這種說法轉向相反的方向,既是,神經元的沖動本質上相同并且以一種“一般流”在神經系統中傳遞!

This course begins with the study of nerve cells which includes their structure , the propagation of nerve impulses and transfer of information between nerve cells , the effect of drugs on this process , and the development of nerve cells into the brain and spinal cord 本課程首先是對神經元的研究,包括神經細胞的結構,神經沖動的傳導和神經細胞間通信和藥物對此過程的作用,以及神經細胞發育為大腦和脊髓的過程。

This course begins with the study of nerve cells which includes their structure , the propagation of nerve impulses and transfer of information between nerve cells , the effect of drugs on this process , and the development of nerve cells into the brain and spinal cord 本課程一開始將針對神經細胞介紹其構造,神經脈沖的傳遞,神經細胞間的訊息傳遞,藥物對訊息傳遞的影響,以及神經細胞在大腦及脊椎的發生學。

According to this theory , it is not the quality of the sensory nerve impulses that determines the diverse conscious sensations they produce , but rather the different areas of the brain into which they discharge , and there is some evidence for this view 譯文:根據這一理論,不是由感覺神經脈沖的質量來決定他們產生的各種神經感覺的,而是由他們被發射到大腦的哪一部位來決定的,對這一觀點是有證據的。

Drug name diphenhydramine , ethanolamine class , histamine receptor type 1 blocker . has significant anticholinergic and sedative properties that causes some degree of topical anesthesia by impairing the transmission of nerve impulses 藥名:苯海拉明,氨基乙醇,組織胺受體1型阻滯劑有顯著的抗膽堿能和鎮靜特性,通過阻礙神經沖動傳導引起某種程度的局部麻醉。

Second , according to the characteristic of the instantaneous change of action potential accompanied by the nerve impulse , we use h - h equation to describe such change , and conduct simulation combined with sr theory 然后根據產生神經沖動時動作電位全或無式瞬時快速變化的特點,采用h - h方程作為描述這種變化的神經元模型,結合隨機共振理論進行了仿真研究。

Drug name viscous lidocaine ( dilocaine ; dermaflex gel ) - - topical anesthetic . decreases permeability to sodium ions in neuronal membranes and results in inhibition of depolarization , blocking transmission of nerve impulses 藥名:粘性利多卡因局部麻醉減少神經元膜對鈉離子的滲透,導致去極化的抑制,阻止神經沖動的傳導。

Drug name viscous lidocaine - - topical anesthetic . decreases permeability to sodium ions in neuronal membranes and results in inhibition of depolarization , blocking transmission of nerve impulses 藥名:粘性利多卡因局部麻醉減少神經元膜對鈉離子的滲透,導致去極化的抑制,阻止神經沖動的傳導。

Minerals are a group of essential nutrients which regulate many body functions such as fluid balance , muscle contraction and transmission of nerve impulses 礦物質能調節身體多項功能,包括體液平衡、肌肉收縮及神經訊號傳送,是一種十分重要的營養素。

Odour material action at smell cell , generation nerve impulse is conducted via olfactory nerve , reach the smell center of pallium finally , form smell 氣味物質作用于嗅細胞,產生神經沖動經嗅神經傳導,最后到達大腦皮層的嗅中樞,形成嗅覺。

At the same time , the scientists implanted another set of electrodes into the brain regions receiving nerve impulses from the right and left set of whiskers 同時,科學家們在大腦區域植人另一套電極,用以接受來自胡須左右兩側的神經刺激。

Anthocyanidins may help protect the retina , the nerve layer that lines the back of the eye and sends nerve impulses to the visual areas of the brain 花青素可幫助保護視網膜:于眼球后部的神經層,負責傳送神經脈沖到腦部視覺神經。

The release of neurotransmitter molecules from one neuron and their attachment to receptor sites on another keep a nerve impulse moving 神經遞質分子從一個神經原釋放后,附著到另一個接受點,令神經沖動保持運動的狀態。

Electrical activity in the form of nerve impulses being sent and received to and from cortical neurons is always present , even during sleep 大腦皮層神經元不停地發送、接收神經沖動信號,即使在睡覺時也不例外。

Nerve impulses carry messages from the environment to the brain for example , the pain you feel when you stub your toe 神經沖動能夠把周邊環境的信息帶到大腦中? ?例如,當你腳趾被絆了一下時,你會感到疼。
