And here's your shmoop du jour brought to you by the occipital lobe it's one of the

00:08

body's most important lobes, along with the frontal lobe the parietal lobe the [Brain with lobes in different colors]

00:12

temporal lobe and the earlobe every family has a weak link.. Clara is going to

00:19

the doctor for a test that will help determine whether or not her occipital [Clara walks into doctors]

00:22

lobe is functioning at a normal level the doctor is going to use a technique

00:26

that examines the difference in levels of oxygen in the brain with the

00:30

understanding that active areas of the brain have greater blood flow. Clara will

00:34

not have to ingest any substances or be exposed to radiation during this process [Clara in a hospital bed]

00:38

which is the following tests will Clara have when she goes to her appointment

00:42

and here are potential answers.... let's

00:48

start with A..A PET scan isn't when spot is looking for the best place to mark [Dog finding a place to pee]

00:53

his territory it's actually a scan that produces a three-dimensional image of

00:57

the functional processes of the body using gamma rays and seeing as a gamma [Person in a CT scan and hulk appears]

01:01

ray is an electromagnetic radiation, this can't be our answer we can also

01:06

lose answer D because x-rays also use radiation or do they use some sort

01:10

of cool Kryptonian magic maybe no just radiation and well that's disappointing moving [Captain America stood next to a car]

01:16

on how about B? An EEG or electroencephalogram try saying that

01:21

five times fast people... measures electrical activity in the brain which is not what [Woman undergoing an EEG]

01:26

we're looking for it also isn't a method of torture despite how it might look

01:30

could it be E.. well an MRI or magnetic resonance imaging uses magnetic fields

01:36

to create detailed images of the body however its focus is on the organs and

01:41

tissues so not the brain not our answer and fMRI the f is for functional is

01:48

similar to a regular MRI but it measures brain activity by detecting associated [Scanned images of a brain]

01:52

changes in blood flow bingo that's what we're looking for maybe if we had some

01:57

Kryptonian powers we would have found it faster well eesh, these krptonians are

02:02

just a laugh a minute.. [Captain America uses krptonian power on a car]
