2d. Scans Flashcards
Unit 2
A procedure in which the two hemispheres are isolated by cutting the thick ribbon-like band of connecting fibers between them
Corpus Callosum
Normal people engage their right brain when completing this
A Perceptual Task
Normal people engage their left brain when completing this
A Linguistic Task
Damage to the brain
Brain Lesion
Studying the physical makeup of the brain (pictures)
Structure (CT/CAT Scan, MRI, fMRI)
Studying an active working brain (brainwaves)
Function (EEG, PET, TMS, fMRI)
Examines the brain by taking x-ray photos from different angles and combining them on a computer into one representation
CAT Scan
Imaging method used that uses computer enhancement to create high resolution images of brain anatomy from exposure to magnetic fields and radio waves (no radiation, no metal allowed)
MRI
A noninvasive imaging method that is used to create amplified recordings of electrical activity across the brain’s surface, measured by electrodes placed on the scalp
EEG (outdated)
A brain imaging method that maps brain activity by monitoring a harmless amount of radioactively tagged glucose introduced into the brain via the blood
PET
A noninvasive imaging method that used magnetic pulses to temporarily enhance of depress activity in targeted regions of the brain
TMS
Studies both structure and function - better quality and within seconds
fMRI
