AP PSYCHOLOGY

Detailed explanation-1: -An electroencephalogram (EEG) is a recording of brain activity. During this painless test, small sensors are attached to the scalp to pick up the electrical signals produced by the brain. These signals are recorded by a machine and are looked at by a doctor.

Detailed explanation-2: -EEG results show changes in brain activity that may be useful in diagnosing brain conditions, especially epilepsy and other seizure disorders. An electroencephalogram (EEG) is a test that measures electrical activity in the brain using small, metal discs (electrodes) attached to the scalp.

Detailed explanation-3: -An electroencephalogram (EEG) is a test used to find problems related to electrical activity of the brain. An EEG tracks and records brain wave patterns. Small metal discs with thin wires (electrodes) are placed on the scalp, and then send signals to a computer to record the results.

Detailed explanation-4: -EEG sensors are placed on a participant’s head, then the electrodes non-invasively detect brainwaves from the subject. EEG sensors can record up to several thousands of snapshots of the electrical activity generated in the brain within a single second.

Detailed explanation-5: -A standard electroencephalogram (EEG) records electrical activity or brainwaves that are representative of underlying cortical brain activity. A quantitative EEG (qEEG) applies sophisticated mathematical and statistical analysis to these brainwaves and compares them to age and gender controls.
