Functional Magnetic Resonance Imaging

This is a brain-scanning technique that measures ___________ in the brain when a person performs a task, and therefore a particular _____________, based on the idea that _______ in the brain are most most active when they are involved in completing a task

Blood flow

Cognitive function neurons

This activity causes neurons to use more ________________ so when a brain region is more active, it prompts the body to ______________ with increased __________ blood flow

Energy and oxygen

Flood that area

Oxygen-rich

This alters how __________ the blood's _______________ is

Magnetic

Haemoglobin

An fMRI scanner detects these differences in the _______________________ and this information is used to create a dynamic 3D map of the brain on a screen

Magnetism of different brain structures

The scans highlight which areas are active during a particular task which then maps out neural activity…

Associated with a particular brain function

This can then be used to infer which _______ of the brain _________ which function

Areas

Regulate

fMRI scans show this activity in an image on a screen approximately ____________ after the function occurs within the brain

Images are accurate to within ______________________

1-4 seconds

1-2mm of brain tissue
