Huxley first encountered the squid giant axon in 1939 , working with hodgkin at the laboratory of the marine biological association in plymouth , uk , and resumed work on it after the war .
Their main finding was that a nerve impulse , now known as an action potential , is caused by the movement in opposite directions across the axon 's surface membrane of sodium and potassium ions .
他们的主要发现是神经冲动,现在被称为是动作电位,动作电位是由轴突表膜上的钠和钾离子反向移动引起的。
There was a hierarchical system in neurobiology , and working in invertebrate animals was not looked upon favorably , except in a very special case : the squid giant axon .
神经生物学中有一个等级系统,无脊椎动物的研究不被看好,除了非常特殊的例子:枪乌贼巨大的轴突。
This image shows a single neuron 's soma and dendrites ( at center , orange ) and the dense branches of its axon ( yellow ) .
这张照片展现了单一神经元的密质部分和树突(中间,橘黄色),以及轴突的浓密分支(黄色)。
When an electrical impulse reaches an axon terminal it communicates across a tiny gap called a synapse . This is referred to as synaptic firing and this is how brain cells or neurons communicate with one another .
From this description , it is clear that dieters easily differentiated between the dendrites and the axon , but that he did not know if the axon arose from the cell body or from the dendritic tree .
