Ways Of Studying The Brain

Question 1

FMRI

Answer 1

• uses magnetic field and radio waves to monitor blood flow
• it measure the change in the energy released by haemoglobin, reflecting activity of the brain to give a moving picture of the brain

Question 2

Limitations of fMRI

Answer 2

• expensive so leads to reduced sample size negatively impacting the validity of the research

Question 3

EEGs

Answer 3

Electrodes are put on the scalp and detect neuronal activity directly below where they are placed
- differing number of electrodes can be used depending on focus of the research

Question 4

Limitations of EEGs

Answer 4

-have poor spatial resolution
