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.
These stories were popularized for the mainstream audience in the late 19th century by Joel Chandler Harris (1845â1908), who wrote down and published many such stories that had been passed down by oral tradition. Harris also attributed the birth name Riley to Br'er Rabbit. Harris heard these tales in Georgia.
