Document Summary
Provide measures of when and what brain regions activate during movement. Measure fast electro-chemical processes in the brain. Very poor spatial resolution is a limitation of these two techniques; provides. They detect when axon is fired (neuron activation) See the parts of the brain that is active while an individual performs a task a crude understanding of what part of the brain is active but not precise area of the brain. The brighter the area, the greater the activation. Mri provides structural scan fmri provides an integration of structure and function; it will provide images of what is active via very high spatial resolution; these are very expensive and it has very poor temporal resolution. It takes pictures between 5 to 10 seconds but you don"t know what happens in between those time periods. Due to this limitation, it has poor temporal resolution.
