"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

WebSep 4, 2024 · It can be generated when a neuron’s membrane potential is changed by chemical signals from a nearby cell. In an action potential, the cell membrane potential changes quickly from negative to positive as sodium ions flow into the cell through ion channels, while potassium ions flow out of the cell, as shown in Figure 11.4. 3. WebWhat isn't controversial is that the function of a neuron is to receive INPUT "information" from other neurons, to process that information, then to send "information" as OUTPUT to …

WebThe formation of an action potential can be divided into five steps: (1) A stimulus from a sensory cell or another neuron causes the target cell to depolarize toward the threshold potential. (2) If the threshold of excitation is reached, all Na+ channels open and the membrane depolarizes. WebMar 29, 2024 · This occurs through a process known as neurotransmission.
