A structural MRI allows us to see brain activity associated with specific thoughts or behaviors.

Parts of the _______________ are involved in social judgment, rational decision making, and the ability to set goals and to make and carry through plans.

Functional MRI can tell where something is happening in the brain better than an EEG.

Which of the following is a chemical messenger?

Neurogenesis is the process by which dopamine molecules cross the blood-brain barrier.

In the peripheral nervous system, _______________ carry messages from special receptors in the skin, muscles, and other internal and external sense organs to the spinal cord, which sends them along to the brain.
