The rhythmic bursts of brain activity that occur during Stage 2 sleep are called sleep spindles. These are short bursts of brain waves that help in the consolidation of memories and are characteristic of this stage of sleep.
It happens in the 4th stage
There are 4 stages of sleep: Stage 1, Stage 2, Slow wave sleep, and REM. The stages occur in that order. Stage 1 occurs as you are falling asleep, and REM occurs last and contains the craziest dreams. REM is the most difficult to awaken from, so it is likely the stage that you have heard referred to as 'deep sleep'.
metaphase
The second stage of the mitotic phase, called metaphase, overlaps with the first stage, called prophase, in terms of time. This means that while one cell is going through metaphase, another cell in the same population may be in prophase. However, the events that occur in these two stages are distinct. In prophase, chromosomes condense and the nuclear envelope breaks down, while in metaphase, the condensed chromosomes align at the center of the cell.
