About Membrane Potential, Ion Channels and Action Potentials

GoConqr Original

What this page covers

This unit sits in the Cellular and Molecular Neuroscience strand of Neuroscience. It follows one idea from start to finish: how a neuron builds an electrical charge across its membrane, and how it uses that charge to send signals. The resources were made by GoConqr users, mostly from their own university lectures.

Where to begin

Start with the basics of the resting state. The mind map Resting Membrane Potential explains how the uneven distribution of ions makes the inside of the neuron negative compared with the outside. Neurons (1) adds the roles of sodium and potassium, unequal permeability and the equilibrium potential. The flashcard deck 29: neuronal communication asks what a membrane potential is and how the equilibrium potential can be calculated.

Moving on to signals

Next, read the Action Potentials mind map. It covers depolarisation, repolarisation and hyperpolarisation, and the large movement of sodium ions across the axonal membrane. Then try Week 3: Action Potential Propagation, which looks at how electrical signals spread passively along nerve fibres. Electrical Signalling ties the ions to rapid, long-distance communication within a neuron.

For ion channels, look at the mind maps Voltage gated ion channels, Voltage-gated Potassium Channels and Week 6: Ion channels. The flashcard deck Voltage-gated Sodium channels is a good match for them.

Using quizzes and maps together

Take a quiz before you read, to see what you already know. COGS100 Weeks 1 and 2 revision quiz asks about the typical resting potential, action potential amplitude and passive current flow. Lession 1: The Resting Potential is another short check. Then go back to the maps for the topics you missed. Finish with flashcards, which suit quick repeat practice.

Going further

When the basics feel settled, the quiz Synaptic Plasticity and the flashcard deck Synapses lead on to communication between neurons. Teachers can pick maps and quizzes to share with a class as a starting point.

Pick one map today, try a quiz on it, and then make a few flashcards of your own.

Frequently asked questions

Which resource should I open first?

Start with the Resting Membrane Potential mind map. It explains why the inside of a neuron is negative relative to the outside, which everything else on this page builds on. After that, move to the Action Potentials mind map and then try a quiz to check what stayed with you.

What do the action potential resources cover?

The Action Potentials mind map covers depolarisation, repolarisation and hyperpolarisation, and the large movement of sodium ions across the axonal membrane. Week 3: Action Potential Propagation looks at how signals spread along nerve fibres. There is also a slide set on an action potentials essay.

Are there resources on ion channels specifically?

Yes. You can open mind maps on voltage gated ion channels, voltage-gated potassium channels and the Kv potassium channel family. There is a flashcard deck on voltage-gated sodium channels and a note on potassium channel diversity. Together they give you several ways to study the same topic.

Who are these resources for?

They are all at university level, so they suit university students going over a topic or filling gaps. Teachers can also use them as ready-made material for a class. They come from many different courses, so the wording and depth vary from one resource to another.

Are the resources free, and who made them?

Every resource listed here is free to open, study and take, with no account needed. They were made by GoConqr users, not by GoConqr itself. A free account also saves your quiz scores and lets you make your own quizzes, mind maps, flashcards and notes.

What if I can't find the exact topic I need?

Try a nearby resource first. Titles such as Ions, Channels or Electrical properties of neurons often cover related ground. If a topic is still missing, you can build your own mind map or flashcard deck and keep it alongside the others.
