Sonal is at a brain research center, participating in a study. She is hooked up to a machine that measures electrical activity in her brain through the use of electrodes attached to her scalp.
This description best characterizes which of the following techniques?

a. electroencephalography
b. lesioning
c. positron emission tomography
d. magnetic resonance imaging
e. computed tomography

a. electroencephalography

Explanation:

The electroencephalogram is a test that is used to check and examine the activity of the brain. It tracks and records the electrical brain wave activity. This involves the attachment of the metal disc on the scalp and sends the signals to the computer to record the results of the brain activity.

This technique is useful for the diagnosis of epilepsy, sleep disorders, coma, anesthesia and all brain related disorders can be diagnosed through electroencephalogram.

The given situation indicates the use of electroencephalography according to the technique used.

answer:

Ordinary people can do ordinary things like cook, clean, and entertain themselves much easier.
