Solution
The two procedures that allow researchers to view changes in brain activity over time are the Positron Emission Topography (PET) scan and the Functional Magnetic Resonance Imaging (fMRI) scan.
Here's why:
-
Positron Emission Topography (PET) Scan: This procedure involves injecting a small amount of radioactive material into the body, which is then detected by the PET scanner. The scanner then produces a detailed image of the brain, showing areas of activity and function. This allows researchers to view changes in brain activity over time.
-
Functional Magnetic Resonance Imaging (fMRI) Scan: This procedure uses magnetic fields and radio waves to produce detailed images of the brain. Unlike a regular MRI, an fMRI can capture changes in brain activity by detecting changes in blood flow. This means that researchers can see which parts of the brain are active during certain tasks or thoughts, allowing them to view changes in brain activity over time.
