Document Summary
There are several resources you can use to complete the preparation guide (see the list below): Steve hall: chapter 5 of your text book, psyktrek 3. 0 unit 4 all modules, the american psychological association website: http://www. apa. org, discovering psychology video series: http://www. learner. org/resources/series138. html. To start with, make sure you view the following video: The electroencephalograph (eeg) is a device that monitors the electrical activity of the brain over time by means of recording electrodes attached to the surface of the scalp. Ultimately, the eeg summarizes the rhythm of cortical activity in the brain in terms of line tracings called brain waves. Human brain-wave activity is usually divided into four principal bands, based on the frequency of the brain waves. Circadian rhythms are the 24-hour biological cycles found in humans and many other species. In humans, circadian rhythms are particularly influential in the regulation of sleep. A small structure exists in the hypothalamus called the suprachiasmatic nucleus (scn).
