Slow-wave sleep is characterized by stages III and IV of non-REM sleep. This is the deepest phase of sleep, during which the brain waves slow down significantly compared to the waking state. This phase is also known as delta sleep because it is characterized by delta waves, which are low-frequency (0.5 to 4 Hz), high-amplitude brain waves.

Here are the steps to answer the question:

1. Slow-wave sleep does not include sleep spindles. Sleep spindles are characteristic of stage II of non-REM sleep, not slow-wave sleep.

2. Slow-wave sleep includes stage III and stage IV sleep. These are the deepest stages of non-REM sleep, characterized by delta waves.

3. Slow-wave sleep does not occur only once a night. It typically occurs in several cycles throughout the night, with each cycle lasting about 90 minutes.

4. Slow-wave sleep is not characterized by rapid eye movements. Rapid eye movements are characteristic of REM sleep, not slow-wave sleep.

5. Slow-wave sleep is not characterized by EEG oscillations in the 100 to 200 Hz range. The EEG during slow-wave sleep shows delta waves, which are much lower in frequency (0.5 to 4 Hz).
