Question

Quizplus · Accepted Answer

Caffeine is known for its ability to promote wakefulness and mental alertness, as it increases the release of dopamine in the prefrontal cortex and blocks the effects of adenosine, a neurotransmitter that promotes sleepiness. Nicotine, cocaine, and amphetamines can also increase dopamine release, but they have other effects on the body and brain that make them less suitable choices for promoting wakefulness and mental clarity.
