An EEG can show what state a person is in -- asleep, awake, anaesthetized -- because the characteristic patterns of current differ for each of these states. One important use of EEGs has been to show ... The bonnet contains electrodes that pick up impulses from the brain. The EEG shows the electrical impulses of the brain.

Brain cells communicate with each other by producing tiny electrical impulses. In an EEG, this faint electrical activity is measured by putting electrodes on the scalp. ... The EEG may be done to show that the brain has no activity, in the case of someone in a deep coma. It can be helpful when trying to decide if someone...
