So for choice a, which is a pet scan, and that is a visual, that is a visual display of brain activity.
00:28
And during the scan, they would have the individual consumed glucose, which would be sugar, and see, and look at brain activity.
00:40
So that would not be the correct answer because we're looking at x -rays that create brain images.
00:46
So pet scan would not be the correct choice for this one.
00:50
And then for b, which is functional mri, which is reviewed fmri.
00:59
That is a technique for looking at blood flow.
01:06
So that again, this choice is also not looking at x -rays...
