Heroin, cocaine, amphetamines, alcohol, and nicotine are all addictive drugs that increase levels of which of the following neurotransmitters in the brain?
- A.
  
  Serotonin
- B.
  
  Melatonin
- C.
  
  Norepinephrine
- D.
  
  Dopamine
Correct Answer
D. Dopamine

Explanation
Heroin, cocaine, amphetamines, alcohol, and nicotine increase levels of dopamine in the brain. Dopamine is a neurotransmitter that plays a key role in the brain's reward and pleasure pathways. When these addictive drugs are consumed, they stimulate the release of dopamine, leading to feelings of euphoria and reinforcing the desire to continue using the drug. This increase in dopamine levels can create a powerful addiction and contribute to the harmful effects of these substances on the brain and body.

- B.
  
  Is less potent than mescaline in the effects that produced

  Can produce severe delirium tremens in chronic users.
- D.
  
  Can produce psychotic reactions, especially in people who are psychologically unstabel.
Correct Answer
D. Can produce psychotic reactions, especially in people who are psychologically unstabel.

Explanation
LSD can produce psychotic reactions, especially in people who are psychologically unstable. This means that individuals who already have mental health issues or are emotionally vulnerable are more likely to experience severe psychological symptoms when taking LSD. These reactions can include hallucinations, delusions, paranoia, and other symptoms associated with psychosis. It is important to note that LSD can affect individuals differently, and these reactions may not occur in everyone who uses the drug. However, it is a potential risk, particularly for those with pre-existing psychological instability.

- D.
  
  Is the most widely used non physically addictive drung in the world
Correct Answer
A. Is the most widely used psychoactive drug in the world

Explanation
Caffeine is considered the most widely used psychoactive drug in the world because it has stimulating effects on the central nervous system. It acts by promoting the release of adenosine in the brain's prefrontal cortex, which leads to increased alertness and wakefulness. This explanation highlights caffeine's psychoactive properties and its widespread use among individuals.

Correct Answer
D. Depressant

Explanation
Alcohol is classified as a depressant because it slows down the central nervous system, resulting in decreased brain activity and a general sedative effect. It can cause relaxation, drowsiness, impaired coordination, and slowed reaction times. This classification is based on the physiological effects of alcohol on the body, which are opposite to those of stimulant drugs that increase brain activity.

According to the research discussed in your text, ____ seems to help in consolidating memories, particulary new procedural memories, which involve learning a new skill or task.
- A.
  
  REM sleep and NREM stage 2 sleep

- C.
  
  The newly discovered neurotransmitter, hypocretin
- D.
  
  Only REM sleep
Correct Answer
A. REM sleep and NREM stage 2 sleep

Explanation
REM sleep and NREM stage 2 sleep seem to help in consolidating memories, particularly new procedural memories. This means that during these stages of sleep, the brain is actively involved in solidifying and strengthening the memories related to learning new skills or tasks. This research suggests that getting enough REM sleep and NREM stage 2 sleep is important for memory formation and retention.

The active ingredient in marijuana is
- A.
  
  Serotonin
- B.
  
  Lysergic
- C.
  
  THC
- D.
  
  Psilocybin

C. THC

Explanation
THC, or delta-9-tetrahydrocannabinol, is the active ingredient in marijuana. It is a psychoactive compound that binds to cannabinoid receptors in the brain, leading to various effects such as euphoria, relaxation, and altered perception. THC is responsible for the "high" experienced when marijuana is consumed, and it also has potential therapeutic uses for medical conditions such as chronic pain, nausea, and muscle spasms.

Moderate or heavy use of MDMA (ecstasy) can lead to irreversible damage to the brain's ______ system?
- A.
  
  Dopamine
- B.
  
  Anandamide
- C.
  
  Serotonin
- D.
  
  Endorphin
Correct Answer
C. Serotonin

Explanation
Moderate or heavy use of MDMA (ecstasy) can lead to irreversible damage to the brain's serotonin system. MDMA primarily affects the release and reuptake of serotonin in the brain, leading to an increase in serotonin levels. However, prolonged and excessive use of MDMA can deplete the brain's serotonin levels and damage the serotonin neurons. This can result in long-term changes in mood, memory, and cognitive function, as serotonin plays a crucial role in regulating these processes.

Lastly, influencing or changing behavior refers to using psychological knowledge to modify or shape behaviors in a desired way.
