单芯片实现大脑与AI高速无线连接

Core Insights - A new brain-machine interface called the Cortical Biointerface System (BISC) has been developed by research teams from Columbia University, Stanford University, and the University of Pennsylvania, showcasing transformative clinical potential [1][2] - BISC is a single-chip implant that is only 50 micrometers thick and approximately 3 cubic millimeters in volume, allowing for minimally invasive insertion between the brain and skull, significantly reducing surgical trauma and tissue rejection risks [1][2] - The chip integrates 65,536 electrodes and features a wireless data link with a bandwidth of 100 megabytes per second, enabling real-time transmission of brain neural signals to external computers with a data throughput at least 100 times greater than existing devices [1][2] Industry Impact - The high bandwidth and minimally invasive nature of BISC are expected to have profound implications for neuroscience and clinical medicine, potentially allowing paralyzed patients to regain control of limbs or external devices, and enabling speech for those with aphasia [2] - BISC has the potential to revolutionize the management of neurological disorders ranging from epilepsy to paralysis by transforming the cortical surface into an effective "portal" for high-bandwidth communication between the brain and AI or external devices [2][4] - The research team is currently developing a commercial version of the BISC chip to facilitate its application in preclinical and future human patient settings [3]
