chapter 1

Mapping the Brain

• What are the first 2 ways of studying the brain?

• Electrodes-Define– How so they study the brain?

• Electroencephalogram- Define– What is it compared to?

• Needle Electrodes- Define • What is paradoxical about the brain?

Mapping the Brain (con’t)

• PET Scan (Positron Emission Tomography)- Define– How does it work?– What does it allow researchers to “see?”

Mapping the Brain (con’t)

• MRI (Magnetic Resonance Imaging)- Define– Explain– Functional MRI- Explain

Mapping the Brain (con’t)

• What is the word of caution?

A Tour Through the Brain
