Which of the following ways of studying the brain measures general brain activity such as that associated with sleep or arousal?
A
Post-mortem examination
B
fMRI
C
EEG
D
ERPs
Explanation: 

Detailed explanation-1: -Electroencephalogram (EEG for short) is a widespread technique that helps to monitor the electrical activity of the brain. In particular, it can be used to examine, recognize and compare different states of brain consciousness such as sleep, wakefulness or general anesthesia.

Detailed explanation-2: -The basic recordings done during a sleep study may include: Electroencephalography (EEG) . This measures brain wave activity. Electrooculogram (EOG).

Detailed explanation-3: -The hypothalamus, a peanut-sized structure deep inside the brain, contains groups of nerve cells that act as control centers affecting sleep and arousal.

Detailed explanation-4: -Electroencephalography (EEG) First discovered about a century ago, EEG measures electrical activities of the brain from electrodes placed on the scalp.

Detailed explanation-5: -Electroencephalogram (EEG) is a test that looks at the function of the brain. The brain works by a series of nerve impulses, which cause electrical signals. These signals (also called brainwaves) can be recorded through the scalp.
