Unscramble the Blue Letters


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 crlaossom with students. We're going to do an enimerepxt 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 cmniog from neurons in my hreat 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 snagil 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 barin encodes ifinrootamn in the form of an action pioanttel.

This is a way that the brain encodes information in the form of an action potential.
