measures blood flow to the brain when someone performs a task, neurons are most active during tasks that use the most energy.
FMRI- method?
depict and create a 3D moving map of the brain. highlighting the areas involved. shows activity 1-4 seconds after and accurate to 1-2mm
Strength?
non-invasive and is risk free, allows more patients/ppts to undertake fMRI scans which could help further data on the functioning of the human brain.
Weakness?
high cost and low practicality
weakness?
lack of precision makes interpretations difficult since areas that light up on images may overlap with different actions so hard to determine origin
strength?
good spatial resolution. allows psychologist to discriminate between different brain regions with greater accuracy. allows psychologists to determine the activity of different brain regions with greater accuracy.
