* '''Neuropharmacology''' — The study of how drugs affect cellular function in the nervous system and the neural mechanisms through which they influence behavior.
* '''Neurotransmitter''' — A chemical messenger that carries signals between neurons (e.g., Dopamine, Serotonin, GABA).
* '''Synapse''' — The "Gap" between two neurons where the chemical message is sent.
* '''Reuptake''' — The process by which a neuron "Vacuums up" its leftover neurotransmitters to reuse them.
* '''Blood-Brain Barrier (BBB)''' — The "Security Guard" of the brain; a tight filter that prevents most drugs from entering the brain.
* '''Classes of Psychoactive Drugs''':
** '''Stimulants''' (Uppers) — Speed up the brain (e.g., Caffeine, Cocaine).
** '''Depressants''' (Downers) — Slow down the brain (e.g., Alcohol, Xanax).
** '''Hallucinogens''' — Change the way the brain perceives reality (e.g., LSD, Psilocybin).
** '''Antipsychotics''' — Used to treat serious mental illnesses like Schizophrenia.
* '''Tolerance''' — When the brain "Adapts" to a drug, requiring a larger dose to get the same feeling.
* '''Withdrawal''' — The painful "Crash" when a brain that has adapted to a drug is suddenly forced to work without it.
* '''Excitatory vs. Inhibitory''' — Some neurotransmitters tell the brain to "Fire" (GO), while others tell it to "Stop" (STOP).
