The brain can unlock true multitasking after intensive training (medicalxpress.com)

Georgetown University researchers have discovered that the brain can adapt its neural circuitry to enable true multitasking following extensive training. This challenges the prevailing belief that humans can only switch between tasks, revealing instead that significant practice can allow the brain to automate learned tasks, effectively bypassing the prefrontal cortex—the area historically associated with focused executive function. The study, which involved participants sorting morphed images of cars over 30,000 trials, demonstrated that expertise in a task can move the cognitive load from the prefrontal cortex to the temporal cortex, enhancing multitasking capabilities and freeing cognitive resources for additional activities. This groundbreaking work has profound implications for both human learning and artificial intelligence (AI). By understanding how the brain remaps itself for efficiency, insights can be gained for developing AI systems that mimic this adaptive learning. Unlike current AI models, which typically struggle with integrating new skills based on prior learning, this research suggests pathways for creating more sophisticated algorithms that can improve performance through experiential training. Further investigations will explore the mechanisms behind this transfer of knowledge and the potential limits of multitasking, offering exciting avenues for enhancing both cognitive science and AI development.
