Скачать или смотреть Neuroplasticity and Drugs (AP Psychology Unit 2.8)

Don't do drugs kids. Here are the key terms with some definitions:

Neuroplasticity: Neuroplasticity refers to the brain's ability to reorganize itself by forming new neural connections throughout life. It allows the brain to adapt to new experiences, learn new information, and recover from injuries.

Depressants: Depressants are a class of drugs that slow down the central nervous system's activity. They often induce feelings of relaxation and drowsiness. Examples of depressants include alcohol, benzodiazepines, and certain sleep medications. Research has shown the impact of depressants on neurotransmitter systems, especially gamma-aminobutyric acid (GABA), which leads to their calming effects.

Stimulants: Stimulants are substances that increase the activity of the central nervous system, leading to heightened alertness, energy, and euphoria. Common stimulants include caffeine, amphetamines, and cocaine. Research, like studies on dopamine release, has elucidated how stimulants affect neurotransmitter systems to produce their stimulating effects.

Hallucinogens: Hallucinogens are drugs that alter perception, thoughts, and feelings, often causing hallucinations or profound alterations in consciousness. Examples include LSD, psilocybin mushrooms, and MDMA. Research into the effects of hallucinogens, especially psilocybin, has gained attention in recent years for their potential therapeutic benefits and their impact on brain connectivity.

Addiction: Addiction is a complex condition characterized by compulsive drug-seeking and use, despite harmful consequences. It often involves changes in the brain's reward and motivation systems. Research, such as studies on the role of dopamine and the mesolimbic pathway, has shed light on the neurobiological mechanisms underlying addiction.

Withdrawal: Withdrawal refers to the physical and psychological symptoms that occur when a person stops using a substance they have become dependent on. These symptoms can include cravings, anxiety, depression, and physical discomfort. Research has shown that withdrawal is a manifestation of the brain's efforts to readjust to a state of normal functioning after prolonged substance use.
