Brain-computer interface(BCI)technology achieves a direct transformation from thought to action by converting neural signals in the subject's brain into commands to control external devices.Many researchers believe that BCI demonstrates that cognitive processes can be realized in a disembodied manner,suggesting that the body's perceptual-motor processes are not indispensable for cognition.From the perspective of predictive processing,the implementation of BCI still heavily relies on the subject's prior embodied knowledge and"virtual"body action patterns,indicating that the experiential structure of the body plays a significant constructive role in cognitive processes.Such investigations not only help deepen our understanding of the prin-ciples,technical implementation,and application prospects of BCI but also contribute to expanding our comprehension of embod-ied cognition-related philosophical positions and reconsidering the deep relationship between the brain,body,and world from a new perspective.
