Functional Magnetic Resonance Imaging (fMRI)

The video tutorial explains the development and function of fMRI technology, which measures changes in brain metabolism by detecting blood oxygen levels. Unlike PET scans, fMRI is non-invasive and allows repeated experiments. The tutorial details the setup of fMRI experiments, particularly in vision studies, and discusses participant recruitment, emphasizing the importance of volunteers without ulterior motives.

What is the significance of measuring blood oxygen levels in fMRI?

What precautions are taken when selecting volunteers for fMRI studies?
