Identifies the changes in levels of
oxygen
in blood that occurs due to
brain
activity in specific areas - high
spatial
resolution
When a
brain
area is more active, it leads to more
oxygen
being used so there is an increase of
blood
flow to this active area
fMRI produces a
3D
image showing which part of the brain is
active
, called an
activation map
It has been used to identify which
specific
parts of the brain are
active
in particular mental
processes
(showing
localisation
of function)
They have a
time delay
-
low
temporal resolution
