---------------------- www.psychlotron.org.uk ---------------------- Name of resource: Stages of sleep & the sleep cycle IWB activity Submitted by: Aidan Sammons Specification details: AQA-A Other specifications: Edexcel? Guidance: animated 'EEG' that displays traces for waking and the different stages of sleep. Start the presentation in the usual way (press f5) and it opens with a waking EEG trace. Press one of the buttons at the bottom of the oscilloscpe to display traces for stages 1-4 and REM. Pressing 'C' gives a graph of the sleep cycle over 8hrs. This takes about a minute to display fully so you can talk over it. The timings are pretty easy to tinker with if you want to make it faster. Made in PowerPoint 2003 and should work in PowerPoint XP but may not work properly with earlier versions so make sure you test it before use.
