Heroin, cocaine, amphetamines, alcohol, and nicotine are all addictive drugs that increase levels of which of the following neurotransmitters in the brain?

Serotonin
Melatonin
Norepinephrine
Dopamine

Correct Answer

A. 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.

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

Correct Answer

A. 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.

Caffeine:

Is the most widely used psychoactive drug in the world
Gets its stimulant effect by promoting the release of adenosine in the brain's prefrontal cortex.
Gets its stimulant effect by blocking the reuptake of dopamine, serotonin and norepinephrine.
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.

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.

REM sleep and NREM stage 2 sleep
NREM stage 1 slow wave sleep
The newly discovered neurotransmitter, hypocretin
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.

Moderate or heavy use of MDMA (ecstasy) can lead to irreversible damage to the brain's ______ system?

Dopamine
Anandamide
Serotonin
Endorphin

Correct Answer

A. 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.
