What is Phase response curve (PRC)?

A phase response curve is like a map that shows how something changes its rhythm when it gets a little nudge.

Imagine you're on a swing. You go up and down in a steady rhythm, that’s your rhythm. If someone gives you a gentle push at just the right moment, you might go higher. But if they push you when you’re going down, you might not go as high, or even slow down a bit.

A phase response curve is like a chart that tells us how a rhythm changes based on when it gets a nudge. It shows what happens to the timing of the rhythm, whether it speeds up, slows down, or stays the same, depending on when the nudge happens.

Think about your heartbeat. Your heart beats in a steady rhythm. If something causes a little change, like a signal from your body, your heart might beat just a tiny bit faster or slower. A phase response curve helps scientists understand how these nudges affect the timing of your heartbeat.

It's like having a friend who knows exactly when to push you on the swing so you go higher, that’s what a phase response curve does for rhythms in our bodies!
