Document Summary
Lecture 5: brain activity measurements: describing the movement. Measures of brain activity: provide measures of when and what brain regions activate during movement. Mmse mini mental state exam (score of 24 is meaningful because they are really impaired, scored out of. Under 24 is clinically important with suspected mci. Any score greater than 25 is okay, not perfect. Less than 24 has impairment, poor memory and skill in performing a rehabilitation skill. Verbally describing a skill is not effective and the patient will not be able to follow the skill. Eeg good temporal resolution and can measure electrical activity in the brain, cheaper technique. Measures of direct activation in the brain: Meg more sophisticated, can measure fine temporal resolution faster than eeg. Both provide measure of synaptic communication, direct measure of electrical activity in the brain. If you perform a cognitive action, eeg and meg can quantify the firing.
