Which technique records the BOLD signal?

D) PET
E) MEG

Question

Quizplus · Accepted Answer

The technique that records the BOLD signal is functional magnetic resonance imaging (fMRI). Therefore, the correct option is C. MRI (A) also uses magnetic fields to create images of structures inside the body, but it cannot record the BOLD signal. CT (B) uses X-rays to generate images and is not capable of recording the BOLD signal. PET (D) and MEG (E) are imaging techniques that measure brain activity, but they do not record the BOLD signal specifically.
