A new study from Princeton reveals that the brain reuses specific modular “cognitive blocks” within the prefrontal cortex to quickly assemble solutions for diverse tasks. Researchers observed monkeys switching between visual categorization challenges and found that the brain does not build a new system for every task; instead, it re-purposes these building blocks. This discovery offers fundamental insights into neural reuse and the underlying efficiency and modularity of biological learning, providing a new model for understanding consciousness and general intelligence.
