Question

Quizplus · Accepted Answer

Norepinephrine is a neurotransmitter that is responsible for alertness, attention, and vigilance. It is released during times of stress or perceived danger, such as being in a war combat zone. The sharpshooter's vigilance and alertness are likely due to the activity of norepinephrine. GABA and endorphins are not associated with alertness and vigilance, and dopamine is more closely related to motivation and reward-seeking behavior rather than vigilance.
