Brain Scans and Imaging Technologies Flashcards
Lesioning
surgically graphing and dissecting the organic structures of the brain - done in autopsies
EEG(Electroecphlograph
record bioelectric activity of brains neural citcuits - used in sleep studies
CT/CAT (Computed Axial Tomography)
3-D veiwing of internal and external structures of the brain, provides cross sectional images of brain’s internal structure
PET Scan(Position Emissions Tomography)
Radioactive glucose is injected into cartoid artery providing energy needed to for brain to preform a task, shows which parts of brain are being used during specific task
MRI(Magnetic Resonance Imaging)
use magnetic waves instead of radiation like CT scans, have better images
fMRI
video recording of brain activity, measure blood flow and oxygen levels
