Resting potential explorer

Explore how ion gradients and selective permeability establish the resting membrane potential — the electrical foundation for all neural signaling.

Week 2 Membrane potential Ion gradients Permeability

Action potential explorer

Step through the five phases of an action potential with an AI tutor that responds to your reasoning. Includes an ion manipulation mode to explore what happens when conditions go wrong.

Myelination explorer

Watch an action potential travel along myelinated, unmyelinated, and MS-model axons simultaneously. Predict the outcome, then fire and observe saltatory conduction in action.

Synaptic transmission explorer

Explore how signals cross the synaptic cleft — vesicle release, receptor binding, and the difference between excitatory and inhibitory synapses.

Visual receptive fields explorer

Trace a signal from retina to LGN to V1 and explore how receptive fields transform at each stage — from center-surround contrast detection to orientation selectivity.
