2-Minute Neuroscience: Action Potential

2-Minute Neuroscience: Action Potential

Welcome to 2 minute neuroscience, where I simplistically explain neuroscience topics in 2 minutes or less. In this installment I will discuss the action potential. The action potential is a momentary reversal of membrane potential that is the basis for electrical signaling within neurons. If you’re unfamiliar with membrane potential, you may want to watch…Continue reading 2-Minute Neuroscience: Action Potential

In this video, I want to talk about the action potentials of neurons. Here we have our neuron with soma in red and a larger than normal axon in green. And now I’ve drawn a myelin sheath in yellow around the axon and a couple of larger than normal dendrites in blue. And here’s our…Continue reading Neuron action potential description | Nervous system physiology | NCLEX-RN | Khan Academy
