Final answer:
EEG stands for Electroencephalogram and is a method to measure the electrical activity of the brain.
Step-by-step explanation:
EEG stands for Electroencephalogram, which is a technique used for recording the electrical activity of the brain via electrodes on the scalp. This method serves to provide a measure of a brain's overall electrical activity, often without pinpointing the exact location of said activity. Unlike an electrocardiogram (ECG), which is a record of the electrical activity of the heart, an EEG is specifically focused on the brain's electric patterns. It is important to note distinctions such as these when studying electrical techniques in medicine.
