methods of studying brain behavior relationships Flashcards
1
Q
electroencephalograph (EEG)
A
records from scalp
measures change by milliseconds, but low resolution of location of signal
2
Q
evoked potentials
A
similar to EEG, but in response to stimuli
3
Q
maonetoencephalohraph (MEG)
A
similar to EEG but measures magnetic fields
4
Q
positron emission tomography
A
measures changes over time and location, but requires exposing brain to radiation
5
Q
functional magnet resonance imaging
A
measures changes over about 1 second, identifies location within 1 to 2 mm; no radiation
6
Q
Computer axial tomography (CAT)
A
maps brain areas, requires exposure to X-rays
7
Q
MRI
A
maps brain areas in detail, using magnetic fields
