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: -An electroencephalogram (EEG) is a test that measures electrical activity in the brain using small, metal discs (electrodes) attached to the scalp. Brain cells communicate via electrical impulses and are active all the time, even during asleep.

Detailed explanation-3: -Brain wave frequency is measured in Hertz (Hz), which is the number of waves per second.

Detailed explanation-4: -EEG machines-which include portable EEG machines, ambulatory EEG machines and EEG neurofeedback machines or EEG biofeedback machines-are monitoring devices used for EEG recordings. EEG stands for electroencephalography, the non-invasive method of monitoring the brain’s electrical signals.
