Brain Region Discovered for Abstract Thought
Researchers discovered the first definitive neural evidence of how the brain creates and reuses abstract symbols to think creatively. The research tracks the neural substrates of “compositional generalization”, the foundational cognitive ability to take familiar components and recombine them into entirely fresh ideas. By observing brain cell activity in primate models during complex touchscreen tasks, investigators located this symbolic engine within the ventral premotor cortex. This discovery upends traditional views of the motor system, offering a mechanistic look at abstract thought while providing templates to optimize brain-computer interfaces (BCIs) and assess cognitive disorders. ….[READ]
