Document Summary
Broca"s area left frontal region, crucial for production of language. Physiological assessment measurements of bodily systems: ex: blood pressure, breathing rate, perspiration rate, examine how bodily functions change in association with behaviors/mental states. Polygraphs lie detector; people who are lying, experience more arousal and stress. Increased blood flow carrying the radioactive material leads these regions to emit more radiation. Downside- need to inject radioactive substance limit use of pet: magnetic resonance imaging (mri) a powerful magnetic field is used to momentarily disrupt the brain"s magnetic forces. Energy is released from brain tissue in a form that can be measured by detectors surrounding the head. Researchers can produce a high-resolution image of brain b/c different types of brain tissue release energy differently. Valuable for providing information about structure of brain; can determine location of brain damage/trauma: functional magnetic resonance imaging (fmri) make use of brain"s blood flow to map the working brain.
