So in order to show that, we have to get some vocabulary out of the way. So I'm going to do what we do in the classroom with students. We're going to do an experiment on electrophysiology, which is the rdecnorig of the body's electrical sinagl, either coming from neurons or from mclsues. And I'm putting some electrodes here on my wtsirs. As I hook them up, we're going to be able to see a signal on the screen here. And this signal may be familiar to you. It's called the EKG, or the electrocardiogram. And this is coming from neurons in my heart that are firing what's clelad action potentials, potential meaning voltage and action meaning it moves quickly up and down, which causes my heart to fire, which then causes the signal that you see here. And so I want you to remember the shape of what we'll be looking at right here, because this is going to be iormptant. This is a way that the brain encodes information in the form of an action potential.

So in order to show that, we have to get some vocabulary out of the way. So I'm going to do what we do in the classroom with students. We're going to do an experiment on electrophysiology, which is the recording of the body's electrical signal, either coming from neurons or from muscles. And I'm putting some electrodes here on my wrists. As I hook them up, we're going to be able to see a signal on the screen here. And this signal may be familiar to you. It's called the EKG, or the electrocardiogram. And this is coming from neurons in my heart that are firing what's called action potentials, potential meaning voltage and action meaning it moves quickly up and down, which causes my heart to fire, which then causes the signal that you see here. And so I want you to remember the shape of what we'll be looking at right here, because this is going to be important. This is a way that the brain encodes information in the form of an action potential.
