Biological approach (assumptions expanded)

Question 1

Define MRI scans

Answer 1

A non-invasive neuroimaging technqiue, that uses radio frequencies and magenetic feilds to produce detailed images of the brain.

Question 2

What are some strengths and weaknesses of the MRI?

Answer 2

STRENGTHS- non invasive (no surgery, radiation or discomfort)
high-resolution images (allows for visualization of structures within the body)
WEAKNESSES- pose risks for patients with metal implants, pacemakers, requires patinets to stay still for a long time

Question 3

FMRI defintion

Answer 3

• Aspecialized MRI technique.
• Used to measure and map brain activity by detecting changes in blood flow and oxygenation levels.

Question 4

Evaluate the FMRI

Answer 4

• Strengths- non invasive (no surgery/injections) Safe (no radiation)
• Weaknesses- expensive to purchase, operate, and maintain,

Question 5

EEG definition

Answer 5

• A machine that measures electrical activity in nerve and muscle cells.
• It uses macroelectrodes on the scalp/ skin

Question 6

EEG strengths and weakneses

Answer 6

• Strengths: Offers High Temporal Resolution thus allows researchers to study the timing and dynamics of neural processes in real-time.
• Weaknesses: Individual differences in skull thickness, and electrode placement can affect the consistency of EEG recordings

Question 7

Phernology

Answer 7

involves the measurement of bumps on the skull to predict mental traits.

Question 8

Post mortem

Answer 8

technique used to examine the brain and body after death.
