Document Summary

Describing the movement: measures of brain activity. Provide measures of when and what brain regions activate during movement. The brighter the colour, the more that area is being activated. Don"t have good enough resolution to figure out the specific region of the brain being activated. Large gaps (about 5 seconds) in time in taking pictures of the brain. Had estimates in what was going on in the brain. Great to use when diagnosing for neurodegenerative diseases like dementia. When put over the left hemisphere: effects speech products. When put on the right side of the brain: speech was fine. You can create a virtual lesion in a healthy individual (creating a short mini stroke) You can study cognitive and motor function (no one is really sure how tms works) Excitation/ inhibition in the corticospinal tract at the moment of simulation. Meps of muscle assessed to examine the release of action.
