With advances in neurophysiology, the recording of electrical activity of brain became possible. Analysis of the brainwave activity during sleep helped in understanding the various different components of sleep and sleep disorders. Polysomnography nowadays gives us a great deal of information about sleep, respiratory, and limb movement characteristics. The modern day sleep physician relies heavily on polysomnography in understanding the sleep disorders of the patients. In this chapter, we go over the various different aspects of a typical sleep study including electrode arrangement, electroencephalogram, electrooculogram including audio and video recordings.
