Psychopharmacology Quiz: Test Your Knowledge for AP Psychology

📚 Quick Study Guide

🧠
• Neurons and Neurotransmitters: Neurons communicate through neurotransmitters, chemical messengers that transmit signals across synapses. Key neurotransmitters include:
🧬
• Acetylcholine (ACh): Muscle movement, memory, and attention. Deficiency linked to Alzheimer's disease.
😃
• Dopamine: Pleasure, reward, motivation, and motor control. Excess linked to schizophrenia; deficiency linked to Parkinson's disease.
😌
• Serotonin: Mood regulation, sleep, and appetite. Deficiency linked to depression.
💪
• Norepinephrine: Alertness, arousal, and stress response.
🧪
• GABA (gamma-aminobutyric acid): Inhibitory neurotransmitter, reduces neural excitability. Deficiency linked to anxiety disorders.
⚡
• Glutamate: Excitatory neurotransmitter, involved in learning and memory.

💡
• Agonists: Drugs that mimic the effects of a neurotransmitter or enhance its action.
🚫
• Antagonists: Drugs that block the effects of a neurotransmitter.
⏰
• Reuptake Inhibitors: Drugs that prevent the reabsorption of neurotransmitters, increasing their availability in the synapse (e.g., SSRIs for serotonin).
🎯
• Blood-Brain Barrier: A protective barrier that prevents many substances from entering the brain.
💊
• Psychoactive Drugs: Chemical substances that alter perceptions, mood, or behavior. Examples include stimulants, depressants, and hallucinogens.
⚖️
• Tolerance: Reduced responsiveness to a drug, requiring larger doses to achieve the same effect.
withdrawal
• Withdrawal: Unpleasant symptoms that occur when a drug is discontinued.
