Which statement best describes equipotential theory in brain function?

• A. Each cognitive function is strictly localized to a single cortical site.
• B. Subcortical networks alone determine brain function.
• C. If sufficient cortical material is intact, the remaining tissue can take over the functions of damaged areas.
• D. Brain functions cannot reorganize after injury.

Answer: (C)

Equipotential theory holds that brain functions are distributed across the cortex and can be taken over by other, undamaged areas if enough healthy tissue remains and the brain is given the opportunity to relearn. This idea explains why, after injury, the remaining cortical material can reorganize and assume the functions of damaged regions through plasticity and rehabilitation. The statement that best captures this is the one asserting that if sufficient cortical material is intact, the remaining tissue can take over the functions of damaged areas. It embodies the notion of distributed processing and compensatory reorganization. In contrast, saying that each cognitive function is confined to a single cortical site reflects strict localization, which equipotential theory rejects. Claiming that subcortical networks alone determine function ignores the cortical basis and the brain's capacity for reorganization. Stating that brain functions cannot reorganize after injury contradicts the core idea of neuroplasticity that underpins equipotentiality.
