ways of studying brain

Question 1

fMRI

Answer 1

measures blood flow in brain when person performs task
–> eg. viewing visual stimulus

3D

increased neural activity in regions of brain requires glucose & oxygen found in oxygenated blood

Question 2

EEG

Answer 2

measures brainwave patterns from thousands of neurons via electrodes
-info processed as electrical activity or nerve impulses

types of EEG patterns:
1) alpha waves
2) beta
3) theta
4) delta

Question 3

ERP

Answer 3

type of brainwave triggered by stimulus like pic or sound which requires cognitive thinking

Question 4

post-mortem

Answer 4

study of brain after death
to link brain areas to observed behaviour deficits
eg. Broca and Wernicke, schizophrenia dopamine

-more detailed examination of anatomical and neurochemical aspects of brain
