Have you ever played with a toy car that has a button to make it go and stop? The FitzHugh-Nagumo model is like a toy car that scientists use to study how nerves and cells work in our bodies.
Think of a nerve or a cell as a road with two lanes. The first lane is like a highway where traffic moves fast and smooth. The second lane is like a bumpy and winding road where traffic is slower.
Scientists can control the traffic on these lanes using a special button just like the one on your toy car. This button controls the flow of electricity in the nerve or cell. If the button is pressed, the highway lane gets busy and the bumpy lane gets empty. If the button is released, the opposite happens.
The FitzHugh-Nagumo model helps scientists understand how the traffic flow affects the behavior of the nerve or cell. They use this model to study different diseases that affect the nervous system like Parkinson's disease, epilepsy, and even heart disease.
So the FitzHugh-Nagumo model is a cool toy car that helps scientists study how nerves and cells work in our bodies. And just like your toy car, scientists can make it go and stop to learn more about how our bodies function.
