fMRI
Magnetic brain imaging
fMRI, or functional magnetic resonance imaging, is a brain-scanning technique that measures neural activity by detecting changes in blood flow.
When a brain region becomes more active, it consumes more oxygen, and fMRI captures these fluctuations to create detailed maps of brain function.
Researchers use fMRI to study everything from language processing to emotional responses, making it a cornerstone of modern neuroscience.
The fMRI showed increased activity in the prefrontal cortex during decision-making tasks.
