Functional magnetic resonance imaging is used to observe brain function by:

A) examining intracellular second messengers.
B) monitoring gene activation.
C) examining changes in blood flow to different parts of the brain.
D) measuring neurotransmitter-receptor binding effectiveness.
E) measuring hormone levels.

Functional Magnetic

Likely refers to functional magnetic resonance imaging (fMRI), a neuroimaging procedure that measures brain activity by detecting changes associated with blood flow.

Blood Flow

The continuous circulation of blood in the cardiovascular system, driven by the heart, delivering nutrients and oxygen to cells and removing waste products.

Brain Function

The activities associated with the brain, including cognition, emotion, memory, and motor skills, essential for survival and daily living.
