Parts of a Neuron and How Signals are Transmitted

WebIons are not supposed to migrate back towards the soma (neuron cell body). This is mainly due to the refractory period. It is period of time after an action potential occurs at one point of the axon when it is impossible to produce another action potential at this point. So, ions cannot go backward because they would diffuse passively and ion ...
