1. Chapter 2 E: Brain Monitoring Tools
A.P. Psychology

2. Do-Now (In Journal)
Why is it important to learn about the brain when studying Psychology?
What roles does it play in human thought and behavior?
What are some ways that neuroscientists monitor brain activity?

3. Monitoring the Brain: Lesions
Tissue destruction
Naturally or experimentally caused destruction of brain tissue

4. Monitoring the Brain: Lesions
How can lesions in the brain help neuroscientists better understand neural activity?

5. Monitoring the Brain: Recording Electrical Activity
E.E.G. (Electroencephalogram):
Amplified recording of the waves of electrical activity that sweep across the brains surface
Measured electrodes placed on the scalp

6. Monitoring the Brain: Neuroimaging Techniques
C.T. (Computed Tomography) Scan:
X-ray photos taken from different angles. combined through computers into a composite representation
Reveals brain damage
“CAT” Scan
P.E.T. (Positron Emission Tomography) Scan:
Visual display of brain activity
Detects where a radioactive form of glucose goes while the brain performs a given task

7. Neuroimaging Techniques: P.E.T. Scan

8. What is the role of radioactive glucose?
Video Clip: P.E.T. Scan
How do neuroscientists use P.E.T. Scans to determine the neural activity of language?
What is the role of radioactive glucose?

9. Monitoring the Brain: Neuroimaging Techniques
M.R.I. (Magnetic Resonance Imaging):
Uses magnetic fields and radio waves to produce computer-generated images of soft tissue
Displays brain anatomy
f.M.R.I. (Functional M.R.I.):
Reveals brain activity and blood flow by comparing successive M.R.I. scans
Displays brain function

10. Monitoring the Brain: Comparing M.R.I. Scans
MRI scan of a healthy individual (left) and a person with schizophrenia (right)

11. What is the difference between a M.R.I. and a f.M.R.I. Scan?
Video Clip: f.M.R.I.
What is the difference between a M.R.I. and a f.M.R.I. Scan?
How do f.M.R.I. Scans display the functions of the brain?

12. Review
Differentiate between the following methods of measuring brain activity:
E.E.G. (Electroencephalogram)
C.T. (Computed Tomography) Scan
P.E.T. (Position Emission Tomography) Scan
M.R.I. (Magnetic Resonance Imaging)
f.M.R.I. (Functional M.R.I.)
