- Synopsis
- This image shows the EEG readings associated with the different stages of sleep. There is a locator dot shown, which will be at the top left of the page when the image is the right way up. The EEG reading for awake is shown first and then five stages of sleep are shown (labelled above each line). Each stage is made up of different types of zigzag lines. There are four different types of sleep activity, which are labelled below each line: alpha, beta, theta, and delta. The first section shows the reading while awake, and is made up of both alpha and beta activity. The alpha waves have slightly taller spikes than the beta waves. Stage 1 sleep is made up of theta activity. This stage is made up of wider taller zigzags. Stage 2 sleep contains a K complex which has steeper, taller zigzag lines. Stage 3 sleep is made up of delta activity at the end, which are steep and wide zigzags. Stage 4 sleep is made of delta activity. REM sleep is made up of theta and beta activity.
