Document Summary

How do we get this information: scan intact brain. See if someone has a clot or has had a stroke. Only shows blood vessels and if they have been damaged, not functions or much of structures. Tons of pictures taken at full rotation and pieced together for a good picture of the brain. When used alongside other scans, gives very good representation of the brain at the time of scan. Inject radioactive glucose to light up the brain to show activity. Red means high activity, blue means little activity. Not for structural information, meant for functional information: evidence from brain damage, direct stimulation of cortex. There are small areas where we show that are dedicated to certain functions (motor, visual etc. : the rest of that space is an association area for each dedicated function. Asked to pass a cup of coffee, cannot piece together the movements to do it. Inability to figure out what face they are looking at.
