Nicotine's effects in the central nervous system include which of the following?

Explanation:
Nicotine functions as a central nervous system stimulant. It binds to nicotinic acetylcholine receptors in brain regions that control attention and arousal, triggering increased neuronal activity and the release of neurotransmitters such as dopamine and norepinephrine. This surge enhances cortical arousal, improves focus, and raises wakefulness, which explains why the effect is described as enhanced concentration, alertness, and arousal. Sedation or drowsiness would be the opposite of nicotine’s typical action, and mood swings can occur with withdrawal or regulation, but the immediate CNS effect of nicotine is increased alertness and concentration.
