Scientists uncover the brain’s hidden learning blocks
AI Summary: In a study conducted by neuroscientists at Princeton University, researchers explored the cognitive flexibility of the human brain compared to artificial intelligence systems. They found that the human brain can efficiently reuse cognitive components—termed "cognitive blocks"—across various tasks, enabling rapid adaptation to new situations. Using rhesus macaques, the study demonstrated that the brain employs shared neural patterns when performing related visual categorization tasks, highlighting the brain's compositionality in learning. The findings, published in Nature, provide insights into the mechanisms underlying flexible thinking and task adaptation in humans.
