Which term describes the sum total of brain neurons and their connections?

• A. Localization
• B. Neuroplasticity
• C. Neural network
• D. Cortical remapping

Answer: (C)

The idea being tested is how we describe the brain as an interconnected system. The term that best captures the sum total of brain neurons and all the connections between them is neural network. It emphasizes that brain function arises from the networks formed by neurons and synapses working together, not just from a single brain region.

Localization points to specific areas responsible for functions, neuroplasticity is about the brain’s ability to change its connections, and cortical remapping refers to a reorganization of functions after injury. In contrast, neural network highlights the entire web of neural connectivity underlying processing and behavior.
