Functional architecture differs from neural architecture in that it describes which aspects?

• A. The modules and information flow between them
• B. The physical brain regions
• C. The electrical activity of neurons
• D. The genetic basis of cognition

Answer: (A)

Functional architecture is about how the system is organized in terms of processing steps and how information moves between its parts. It describes the modules or components and the pathways that carry data among them, capturing what the system does and how its parts cooperate. That’s why describing the modules and the information flow between them is the best match. The physical brain regions correspond to neural architecture, the electrical activity of neurons pertains to neural signals at the cellular level, and the genetic basis of cognition concerns heredity and gene function rather than the organized flow of information through cognitive processes.
