BRAIN IMAGING: Brain imaging lets us look inside the brain without surgery
MRI:BRAIN STRUCTURE
Takes detailed picutures of brain
Shows gray matter and white matter
Uses a strong magnet
Helps find tumors, cysts, and strokes
EEG AND MEG:BRAIN SIGNALS
EEG uses sensors placed on the head
MEG measures tiny magnetic signals
Measure messages from brain cells
Show how fast the brain responds
PET and SPECT: BRAIN ACTIVITY
Show which brain areas are active
Measure blood flow and brain chemicals
Use a small amount of a special tracer
Help doctors study diseases
fMRI AND fNIRS:BLOOD AND OXYGEN
Busy brain areas use more oxygen
Shows the brain's structure and activity
Show changes in blood and oxygen
Different scans provide different information
USES OF BRAIN IMAGING
Helps scitentist study memory and language
Shows the brain's structure and activity
Helps doctors find brain problems
Different scans provide different information
Challenges and the Future
Some scans require people to remain still
One scan cannot show everything
Some machines are very expensive
Scientist combine scans to get better results
BEHAVIORAL RESEARCH, OVERT PERFORMANCE
