Question 3

Explain how the activity of brain cells is measured using autoradiography.

Accepted Answer

Brain cells require glucose as fuel for activity. 2-DG, like glucose, is taken up into neurons, but cannot be used for energy. If a radioactive version of 2-DG is injected into an animal, radioactive 2-DG molecules will accumulate in the brain as a function of the relative activity of those cells. Autoradiography will reveal the presence of radioactive molecules in the brain, with a more intense signal in regions that were more active and a less intense signal in less active regions.
