Question 9 of 57

1

What is BOLD?

Question 10 of 57

1

What is a disadv of BOLD fMRI ?

Select one of the following:

1

    we excite the brain with an RF pulse.

    Then we measured the RF pulse emitted in turn by the brain.

    By measuring how long the brain’s RF pulse takes to decay we can infer the neural activity in that region of the brain.
