Answer:
False. Cocaine primarily affects the neurotransmitter dopamine, not serotonin.
Step-by-step explanation:
Cocaine is a powerful stimulant drug that affects the brain's reward system by increasing the levels of the neurotransmitter dopamine. Dopamine is a neurotransmitter that is involved in the regulation of movement, motivation, and pleasure. When cocaine is ingested, it prevents dopamine from being reabsorbed, leading to an accumulation of dopamine in the brain's synapses. This buildup of dopamine is responsible for the euphoria and heightened pleasure associated with cocaine use.
While cocaine primarily affects dopamine, it can also affect other neurotransmitters, including serotonin. Serotonin is a neurotransmitter that is involved in the regulation of mood, appetite, and sleep. However, cocaine's effects on serotonin are less significant than its effects on dopamine.
Some studies have shown that chronic cocaine use can lead to changes in serotonin levels, which may contribute to some of the negative effects associated with cocaine addiction, such as depression, anxiety, and sleep disturbances. However, the primary mechanism by which cocaine affects the brain is through its effects on dopamine, not serotonin.
