  6. 6. How we think ? What are we thinking about?
  7. 7. These kind of questions are possible to answer for first time in human history. To drift directly to the brain to read out the physical of our thoughts .. Some would say ..To read our minds !
  8. 8. by using specialized used of MRI scanning called “functional MRI”, fMRI for short . That makes possible to see what’s going inside the brain while people are thinking.
  9. 9. Anatomy Physiology
  10. 10. How Does fMRI Scan the Brain?How Does fMRI Scan the Brain? fMRI is based on the idea that blood carrying oxygen from the lungs behaves differently in a magnetic field than blood that has already released its oxygen to the cells.

  12. 12. As the increase in flow exceeds the increase in oxygen consumption, neuronal activity is expressed as a relative increase in oxyhemoglobin compared to deoxyhemoglobin in the activated zones. The relative decrease in deoxyhemoglobin concentration, which has a paramagnetic effect, can be detected by MRI as a weak transient rise in the T2* weighted signal. This is the BOLD contrast principle (Blood Oxygenation Level Dependent)
  13. 13. In other words, oxygen-rich blood and oxygen-poor blood have a different magnetic resonance. (BOLD) signal !(BOLD) signal ! Scientists know that more active areas of the brain receive more oxygenated blood. The fMRI picks up this increased blood flow to pinpoint greater activity. The measurement of blood flow, blood volume and oxygen use is called the blood-oxygen-level-dependent (BOLD) signal.

  15. 15. How Is an fMRI Done?How Is an fMRI Done? 1Patient should wear a hospital gown or his own clothes, but he can't bring anything metal (zippers, clips, glasses).
  16. 16. How Is an fMRI Done?How Is an fMRI Done? 2Patient is lie on a table. His head may be placed in a brace to hold it still. Then he is slid headfirst into the large, cylindrical MRI machine.
  17. 17. How Is an fMRI Done?How Is an fMRI Done? 3 Patient may be given earplugs to mask the sound - MRI machines tend to be very noisy.
  18. 18. How Is an fMRI Done?How Is an fMRI Done? 4Patient will be asked to perform a task that increases oxygenated blood flow to a particular part of his brain. For example, he may tap his thumb against his fingers, look at pictures or answer questions on a computer screen.
  19. 19.   fMRI UsesfMRI Uses The most basic use for fMRI is similar to that of its cousin, MRI. •Spotting injured or diseased tissue. •Monitor the growth of brain tumors. •Determine how well the brain is functioning after a stroke. •Diagnosis of Alzheimer's disease.
  20. 20. Scientists are also investigating several other potential applications for fMRI
  21. 21. 1-Brain Mapping1-Brain Mapping This application determines which parts of the brain handle particular functions. When a patient needs surgery to remove a brain tumor, for example, doctors can first scan the brain to determine exactly where to operate. so they can avoid damaging important brain functions.
  22. 22. 2- Analyzing2- Analyzing emotionsemotions   fMRI can help scientists better understand the nature of sadness and other emotions.
  23. 23. 3-Marketing3-Marketing Advertisers already ask customers how products make them feel and how commercials influence their decisions. Now they can see those reactions firsthand by looking inside consumers' brains.
  24. 24. 4- Detective fMRI4- Detective fMRI fMRIs could end up as a way to effectively read a person's thoughts before he even speaks them. The technology could allow law enforcement to see whether someone is lying or telling the truth. MRIs could catch the next terrorist plot, or the next Green River Killer .
  25. 25.    Gary Ridgway, the Green River Killer, was given a polygraph. The court used the results as evidence that he was lying then he admits that he is the one who killed 48 women.
