for NeuronAction
NeuronAction is an interactive simulator that spans simple single-neuron models to more advanced network-level simulations, helping learners visualize how neural signaling works and how it is disrupted in disorders such as Parkinson’s disease, Alzheimer’s disease, seizures, and sleep disorders.
FEATURED SIMULATIONS
Basic Action Potential
Generate action potentials by adjusting stimulus amplitude, delay, and duration as you explore basic conditions for neural spikes.
The Membrane Tutorial
This tutorial walks through how injecting a current across a lipid bilayer affects the voltage across a model neuron membrane.
Equilibrium Potentials
Explore how the balance of ions across a membrane sets the membrane potential, using the Nernst equation and interactive sliders.
The Na Action Potential
Visualize how Na⁺ and K⁺ conductances create action potentials and experiment with toxins like TTX.
Threshold: To Fire or Not to Fire
Test how spike amplitude changes as stimulus strength crosses threshold and whether AP size saturates.
Voltage Clamping a Patch
Hold voltage steady and observe ionic currents to understand Na⁺ and K⁺ channel dynamics.
Chattering Ion Channels
Coming soon: Explore randomness and gating dynamics of ion channels in patch-clamp recordings.
The Ca Action Potential
Model long-lasting action potentials with calcium channels and cardiac-like dynamics.
The Neuromuscular Junction
Simulate acetylcholine-triggered postsynaptic potentials and understand EPC/EPP dynamics.
Postsynaptic Inhibition
Observe how inhibitory inputs prevent action potentials through well-timed hyperpolarization.
