fMRI (Functional Magnetic Resonance Imaging)
fMRI
A brain imaging technique that shows brain activity in real time. It can reveal which parts of the brain become active when you experience certain thoughts or emotions.
Details
What is fMRI (Functional Magnetic Resonance Imaging)?
fMRI (Functional Magnetic Resonance Imaging) is a non-invasive brain imaging technique that visualizes brain activity. When a specific region of the brain becomes active, blood flow increases to that area — fMRI detects these blood flow changes (the BOLD signal) to visualize brain activity.
How fMRI Works
When neurons fire, oxygen is consumed, and oxygen-rich blood rushes to that region to replenish it. Oxygenated and deoxygenated hemoglobin have different magnetic properties, and MRI equipment can detect this difference.
While conventional MRI shows the structure of the brain (anatomical images), fMRI is revolutionary because it shows what the brain is actually doing (functional activity).
Applications in Mental Health Research
Mindy here to share more. fMRI has enabled groundbreaking discoveries in the mental health field:
Thanks to fMRI research, it has been scientifically confirmed that mental health challenges are genuinely linked to patterns of brain activity — contributing to broader social understanding and empathy around mental health.
💡 Real-Life Example
When viewing a photo of a loved one, an fMRI scan of the brain reveals activation in the ventral tegmental area and caudate nucleus — regions associated with the brain's reward circuit.
