单芯片实现大脑与AI高速无线连接 为治疗多种神经系统疾病带来曙光

Core Insights - A new brain-machine interface called the Cortical Interface 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 a minimally invasive insertion through a small cranial incision, significantly reducing surgical trauma and tissue rejection risks [1] - 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 at least 100 times the data throughput of existing devices [1] Application Impact - BISC's high bandwidth and minimally invasive characteristics are expected to have profound implications for neuroscience and clinical medicine, with potential applications in helping paralyzed patients regain control of limbs or external devices, enabling speech for those with aphasia, and restoring visual perception for the blind [2] - The system transforms the cortical surface into an effective "portal" for high-bandwidth communication between the brain and AI or external devices, potentially revolutionizing the management of neurological disorders from epilepsy to paralysis [2] Commercial Development - The research team is currently developing a commercial version of the BISC chip, aiming to advance its application in preclinical and future human patient settings [3]
