Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which TWO of the following DIRECTLY measure electrical activity in the brain?
A
FMRI
B
EEG
C
ERP
D
Post mortem examinations
Explanation: 

Detailed explanation-1: -ERPs can be reliably measured using electroencephalography (EEG), a procedure that measures electrical activity of the brain over time using electrodes placed on the scalp. The EEG reflects thousands of simultaneously ongoing brain processes.

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: -Electroencephalography (EEG) provides an excellent medium to understand neurobiological dysregulation, with the potential to evaluate neurotransmission. Time-locked EEG activity or event-related potential (ERP) helps capture neural activity related to both sensory and cognitive processes.

Detailed explanation-4: -EEG: Measuring Electrical Activity in the Brain These signals go up and down in intensity, resembling waves: these are your brain waves. We can measure brain waves using a technique known as electroencephalography (EEG), in which small detectors, called electrodes, are placed on a person’s head [1].
