What are electrophysiological recordings?

Electrophysiological recordings are like listening to the heartbeat of tiny brain cells called neurons.

Imagine you have a toy robot that sends messages by flashing lights, each flash is like a thought or action. Now, imagine being able to hear those flashes as sounds instead of seeing them as light. That’s what electrophysiological recordings do: they turn the electrical signals inside brain cells into something we can listen to or see on a screen.

Think of neurons like tiny batteries that send messages by electricity. When they fire, it's like a little lightning bolt. Scientists use special tools called electrodes, which are like tiny microphones, to catch those electrical signals and record them.

This helps scientists understand how brains work, just like you might listen closely to your friend’s voice to figure out what they're saying. By listening to the brain's "voice", we can learn about thoughts, feelings, and even diseases that affect the brain.
