What are neurons and how do they work? In this video, we explain neurons in simple words — from the game of catch analogy (how does your brain tell your hand where to move so fast?) to action potentials, resting potential, depolarization, repolarization, voltage-gated ion channels, the sodium-potassium pump, myelin sheaths, and saltatory conduction. Learn how electrical signals travel from your eyes to your brain in milliseconds, and why neurons are the digital language of the brain.
Whether you're a biology student, a neuroscience enthusiast, or curious about how your brain processes information so fast, this beginner-friendly animated explainer covers it all.
