Definitions:

Stage 3 Sleep

A deep sleep phase within the sleep cycle characterized by delta brain waves, important for physical recovery and growth.

Stage 4 Sleep

Stage 4 sleep, also known as deep sleep, is a period of sleep characterized by slow brain waves, reduced muscle activity, and limited responsiveness, playing a key role in restorative sleep.

Sleep Spindles

Short bursts of brain activity detectable by an EEG that occur during stage 2 of sleep, associated with learning, memory, and brain development.

Stage 2 Sleep

A phase of sleep characterized by specific brain wave activity, including sleep spindles and K complexes, representing a deeper sleep than Stage 1.
