Chapter 2 (The Brain) Study Guide
1. What is a neuron? What are the three basic types of neurons? What is the difference
between a neuron with myelin compared to a neuron that is not myelinated?
2. What is stimulus threshold? All-or-none principle? (domino example in class)

6. “Dendrite” comes from a greek word meaning __________?
7. What disorder has been associated with an excess of dopamine? Which disorder has been
associated with a deficit of dopamine?
