What is the term for brain damage that can be naturally occurring or experimentally induced?

• A. Lesion
• B. Depolarization
• C. Amygdala
• D. Cerebral Cortex

Answer: (A)

Lesion is the term for brain damage that can be naturally occurring or experimentally induced. In neuroscience, a lesion refers to damaged tissue in a specific brain area, whether caused by injury, stroke, disease, or deliberately created in research to study what that region does by observing which functions are impaired. This concept lets scientists map brain regions to their associated abilities by linking damage to deficits. Depolarization is the change in a neuron's membrane potential during firing, amygdala is a brain structure involved in emotion, and the cerebral cortex is a major brain region—none of these describe brain damage itself.
