Ways Of Studying The Brain EEG

Question 1

EEG
Works by:

Answer 1

-Electrodes being placed on scalp using skull cap
-detect small electrical changes resulting from activity of brain cells

Question 2

EEG
what does it produce?

Answer 2

-Electrical signals are graphed over a period
-see general brain activity

Question 3

AO3 strength

Answer 3

P-high temporal resolution
E-enables researcher take a real time recordings of brain activity rather than a still image of brain,
-as is the case with use of FMRI or post-mortem
E-r gain more accurate measure of general brain activity in a particular task
L-providing greater insight to sprocess of brain, activity of brain during sleep, inc validity as a way of studying brain

Question 4

AO3
Limitation

Answer 4

P-low spatial resolution
E-only provide info on general activity in brain
E-cannot pinpoint exact source of neural activity that involved in b, unlike use of ERP
-enable researcher identify specific brain activity in particular task
L-less valuable
