3.4 Flashcards
CTI
x rays through brain. different speeds make and image
MRI
clear images based off neurul region activity on amagnetic field. Placed in a strong magentic fields, alighning then unaligning atoms thus creating an image. METAL. Takes two seconds for scan
DTI
white matter pathways. Good for whitematter, it is new. When head injuries twist damaging white matter
EEG
multiple elctrodes: good for sleep. gives time but not spatial
MEG
not detailed. tiny magnetic fields. Megs do not show spatial
PET
low radioactive in blood,see receptors and tasks has good spacial resolution. based off blood is more active in active brain. show metabolic activity. Take a long time to scan.Radioactive. low temporal
ERP
event related potential. takes note exactly when stimuli is sent
