Document Summary

Neuroimaging: various techniques used to directly or indirectly image the structure and/or function of the brain. Not all neuroimaging is invasive can either be direct or indirect. The time it takes for the ions to return to their alignment is measured by the scanner different tissues each have a unique time frame, and the computer uses this data assemble a detailed image of your body. Can segment the brain to look at volumes of speci c brain regions. Mri"s pinpoint changes in blood ow to the brain localize areas in the brain that are active. Individuals can activate the part of their brain that is involved in movement, even when the individual is sedentary. Diffusion tensor imaging: looking at white matter in the brain white matter connects the brain for communication. Mri is not a direct measure of the brain. Increased blood ow= brain needs more energy to do a task.
