Question

Quizplus · Accepted Answer

A psychoactive drug is a substance that affects the brain and its functions, leading to changes in perception, mood, consciousness, or behavior. These drugs work by interacting with the brain's neurotransmitter systems, such as dopamine, serotonin, or GABA, either by mimicking or blocking their action. Examples of psychoactive drugs include caffeine, alcohol, nicotine, marijuana, cocaine, and hallucinogens. Neuromodulators are endogenous or synthetic compounds that regulate the activity of neurotransmitter systems, while neurotoxins are substances that can damage or destroy neurons, leading to neurological dysfunction or death. Psychoendorphins is not a recognized term in neuroscience.
