2-Minute Neuroscience: Membrane potential and action potential

July 26, 2014


In these two videos, I discuss membrane potential and the action potential. Membrane potential refers to the difference in charge between the inside and outside of a neuron, which is created due to the unequal distribution of ions on both sides of the cell. The term action potential refers to the electrical signaling that occurs within neurons. This electrical signaling leads the release of neurotransmitters, and therefore is important to the chemical communication that occurs between neurons. Thus, understanding the action potential is important to understanding how neurons communicate.

YOUR BRAIN, EXPLAINED

Sleep. Memory. Pleasure. Fear. Language. We experience these things every day, but how do our brains create them? Your Brain, Explained is a personal tour around your gray matter. Building on neuroscientist Marc Dingman’s popular YouTube series, 2-Minute Neuroscience, this is a friendly, engaging introduction to the human brain and its quirks using real-life examples and Dingman’s own, hand-drawn illustrations.
