Question

a. During adolescence
b. During adulthood
c. During infancy
d. During old age

Answer 1

An elderly man or woman during old age has less REM sleep than newborns. Sleep spindles and K-complexes are associated with stage 2 of NREM sleep, which is characteristic of the sleep pattern that evolves through different life stages.

Step-by-step explanation:

The response to the student's question is that an elderly man or woman, during old age, has less REM sleep than newborns. As people age, their sleep patterns change and older adults tend to spend less time in REM sleep compared to newborns who spend the majority of their sleep time in REM. Sleep patterns are known to evolve from infancy, through adolescence, and into adulthood and old age, with REM sleep typically decreasing with age.

In relation to the additional information provided, sleep spindles and K-complexes are most often associated with stage 2 of NREM sleep. This stage is marked by decreases in heart rate and respiration and is characterized by specific brainwave patterns. As we age, the amount of time we spend in each stage of sleep, as well as the characteristics of those stages, such as the presence of sleep spindles or K-complexes, changes.
