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

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

  3. Monitoring the Brain: Lesions • Lesion: • 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. 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. 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.)

  13. Homework • Unit 3-B FRQ: • Unit 3 Key People: • Unit 3 Project: “3-D Brain Model”
