Neurobiology
Build from atoms and ions to neural signalling, synapses, and brain function.
1. Why Is Potential Called Potential?
Understand what electrical potential means and why voltage describes stored electrical potential energy.
1. What Is Everything Made Of?
Start with atoms — the basic building blocks behind chemistry, biology, and neurobiology.
2. Where Does Electricity Come From? ⚡
Understand electrical charge, attraction, repulsion, and why electricity matters in neurobiology.
2. Some Physics and... Wind?
Use simple physical analogies to understand gradients, forces, and why particles move.
3. What Really Travels Down the Axon?
Understand what actually propagates during an action potential and why ions themselves do not travel the entire length of the axon.
3. What Makes an Atom Become an Ion?
Learn how atoms become ions by gaining or losing electrons, and why ions are essential in neurobiology.
4. Why Doesn't the Action Potential Go Backwards?
Learn how refractory periods and voltage-gated sodium channel inactivation make action potentials propagate primarily in one direction.
4. Is There Really Salt in Your Blood? 🩸🧂
Explore what salts are, how they separate into ions in water, and why dissolved ions are essential for the nervous system.
