The basis for many dynamic imaging systems is that active brain regions _____.
A) are warmer than less active brain regions
B) consume more glucose than less active regions
C) have more dendrites than less active regions
D) move slightly more than less active regions.

Question

Quizplus · Accepted Answer

Active brain regions require more glucose to produce energy for neural processes, so they consume more glucose than less active regions. This increased glucose utilization can be detected through imaging techniques such as positron emission tomography (PET) or functional magnetic resonance imaging (fMRI). The other options are not supported by empirical evidence.
