In order to study parts of an animal's brain, researchers may sometimes deliberately damage a part of the brain. They accomplish this by placing into the brain a thin insulated wire through which they send an electrical current that destroys the brain cells at the tip of the wire. This technique is called ________.
A) lesioning
B) ESB
C) EEG
D) CT scan

Quizplus · Accepted Answer

Lesioning is the technique of deliberately damaging a part of the brain to study its function. The other options mentioned (ESB, EEG, and CT scan) do not involve intentionally causing damage to the brain. ESB (electrical stimulation of the brain) involves applying a small electrical current to a part of the brain to stimulate it, EEG (electroencephalogram) involves recording the electrical activity of the brain using electrodes on the scalp, and CT scans (computed tomography) use x-rays to produce detailed images of the brain without damaging it.
