EEG Introduction. An EEG, or electroencephalogram, is a test that can help diagnose epilepsy. During an EEG, the electrical signals of the brain are recorded. This electrical activity is detected by electrodes, or sensors, placed on the patient's scalp and transmitted to a polygraph that records the activity.
life of Riley definition. A life of luxury: âSheila found herself living the life of Riley after she won the lottery.â The expression comes from a popular song of the 1880s, âIs That Mr. Reilly?â, in which the title character describes what he would do if he suddenly became wealthy.
Although the term âLife of Rileyâ first appeared in print in the Hartford Courant in 1911, vaudeville singer Pat Rooney had a comic hit with âIs that You, Mr. Reilly?â as early as 1883, depicting a hotel owner âdoing quite wellâ but with grand dreams.lthough fans of poet James Whitcomb Riley suggest that the term refers to the pleasant country life he described, there is no historical documentation for that theory. In the oldest texts, for instance, âRileyâ is spelled in the Irish style, âReilly.â.
