Method for Studying the BrainShows Structure or Function? Key Words/Phrases Image/Mnemonic Lesion EEG CT Scan PET Scan MRI fMRI
Lesion = tissue destruction; a brain lesion is a naturally or experimentally caused destruction of brain tissue.
Recording the Brain’s Electrical ActivityElectroencephalogram (EEG)
Electroencephalogram (EEG)= an amplified recording of the waves of electrical activity that sweep across the brain’s surface. These waves are measured by electrodes placed on the scalp.
CT (computed tomography) Scan= a series of X-ray photographs taken from different angles and combined by computer into a composite representation of a slice through the body. Also called CAT scan.
PET (positron emission tomography) Scan= a visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task.
MRI (magnetic resonance imaging)= a technique that uses magnetic fields and radio waves to produce computer-generated images of soft tissue. MRI scans show brain anatomy.
fMRI (functional MRI) = a technique for revealing bloodflow and, therefore, brain activity by comparing successive MRI scans. fMRI scans show brain function.
