fmri

    Cards (9)

    • functional magnetic resonance imaging
    • maps brain
    • displays blood flow - oxygenated blood (red) vs deoxygenated blood (blue)
    • performing tasks = certain areas in brain becoming oxygenated
    • ✔️ support for localisation - different parts of brain do different things
    • ✔️unintrusive - don’t need to open up brain to investigate
    • ✔️ high spatial resolution- can clearly see what part of brain is being used - allows psychologists to accurately discriminate between different brain regions
    • X low temporal resolution - 4 second delay, not seeing it in real time = psychologists unable to predict with accuracy
    • X hard to infer causation at a neural level - fmris only measure blood flow
      • changes in blood flow indicate activity in a certain area but psychologists can’t conclude whether this area has a specific function
