Question

Quizplus · Accepted Answer

Epinephrine, also known as adrenaline, is a neurotransmitter that increases attention and concentration by increasing heart rate, blood flow, and oxygen delivery to the brain. Serotonin is a neurotransmitter that is involved with mood regulation, not attention and concentration. Histamine is primarily involved with allergic reactions and inflammatory responses, not attention and concentration. Glycine is an inhibitory neurotransmitter that actually decreases activity in the brain, so it would not increase attention and concentration.
