Question

You want to compare the task-related activity in the human somatosensory cortex in a control versus experimental condition. Which method would you choose?

Select one:

a.
DTI


b.
CT


c.
PET


d.
fMRI


e.
Optogenetics

Answer 1

Answer: d. fMRI

Step-by-step explanation:

Functional magnetic resonance energy is the imaging instrument that determines the functional activities and changes in the blood flow. This technique is useful for examining cerebral flow of blood and the neuronal activation can be analyzed in both control and experimental condition of the somatosensory cortex. When the subject uses the brain the blood flow in the region increases which can be detected by fMRI.
