Answer to Question 1
Answer: Chemical stimulation can be used to excite cell bodies rather than both cell bodies and axons of passage.
Answer to Question 2
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 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.
