Question

Quizplus · Accepted Answer

Animals experience sleep cycles in which they alternate between REM sleep and slow-wave NREM sleep, similar to humans. While there is debate about whether animals actually dream during REM sleep, it is clear that they experience both stages of sleep. Option A is incorrect because studies have shown that some animals do experience periods of brain activity during sleep, indicating that they are possibly dreaming. Option C is incorrect as animals do experience REM sleep, which is not solely restricted to mating season. Option D is also incorrect for the same reason.
