1(a) AO1 (3 marks) 
Up to three marks for describing how an fMRI scan can be used 
to investigate the brain. 
For example: 
• An fMRI scan measures blood flow in the brain whilst a 
person is completing a task (1). When a particular area of 
the brain becomes more active when completing the task 
there is an increased demand for oxygen (1). The brain 
responds by increasing blood flow which allows 
researchers to produce images showing the levels of 
activity in ...
