What is the thalamus?
200
A neural impulse; a brief electrical charge that travels down an axon
What is action potential?

What is the Hypothalamus?
300
The period of inactivity after a neuron has been fired
What is the refractory period?
300
An amplified recording of the waves of electrical activity sweeping across the brain's surface. (These waves are measured by electrodes placed on the scalp)

400
When there is a negative charge inside an axon and a positive charge outside
When is the Neuron said to have a resting potential?
400
Uses magnetic fields and radio waves to produce computer generated images of soft tissue (Shows brain anatomy)
What is an MRI?
