## What is Action Potentials?

In this app, you can see how action potentials work by watching the action potential as it happens and adjusting the parameters. You can add drugs such as lidocaine, tetrodotoxin, and TEA to observe the effects on the action potential. You have the option to see a single action potential with a preset current injection, or a continuous option where you can manually inject current to trigger an action potential.

## Key features

- Real-time action potential visualization
- Adjustable simulation parameters
- Drug effect simulation (lidocaine, tetrodotoxin, TEA)
- Single action potential mode
- Continuous manual current injection


## Frequently asked questions about Action Potentials

### What is Action Potentials?

Action Potentials is an educational application that allows users to visualize and interact with the process of action potentials in neurons. You can adjust parameters and observe the effects of different drugs on neuronal signaling.
