AP PSYCHOLOGY

Detailed explanation-1: -Drugs that bind to neurotransmitter receptors, mimicking the activity of a neurotransmitter chemical binding to the receptor, are called agonists.

Detailed explanation-2: -Acetylcholinergic neurons in particular are active during the dreaming phase of sleep. It seems that the brain recharges neurotransmitter levels with sleep, so sleep ensures that neurotransmitters like dopamine are increased naturally. Studies show that uninterrupted sleep before 12 am has the highest quality.

Detailed explanation-3: -Endorphins like opiate drugs, codeine and morphine are agonists as they bind to the neurons to heighten pleasure or decrease pain.

Detailed explanation-4: -Most neurotransmitters are either small amine molecules, amino acids, or neuropeptides.
