"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 ... " - How does information flow through a neuron

The best-known flow of K + is the outward current following depolarization of the membrane. This occurs through the delayed rectifier channel (I DR), which, activated by the influx of Na +, counteracts the effect of that cation by allowing the discharge of K +.

WebMay 3, 2011 · Neurons pass messages to each other using a special type of electrical signal. Some of these signals bring information to the brain from outside of your body, such as the things you see, hear, and smell. Other signals are instructions for your organs, glands and muscles. Neurons receive these signals from neighbor neurons through their dendrites.
