脑机接口技术不断发展，我们准备好了吗

Core Insights - Brain-computer interface (BCI) technology is advancing, enabling new treatment possibilities for conditions like stroke and paralysis, while also raising ethical and legal challenges [1][3] Group 1: Technology Development - BCI establishes a direct communication channel between the human brain and external devices, acting as a "bridge" that enhances human-machine interaction and opens new avenues for brain science and neurological disease treatment [1] - CorTec, a German company, has developed a BCI that involves placing a 32-channel electrode pad beneath the skull, capable of recording brain activity and providing electrical stimulation [1][2] - The "Neuralink" company has implanted devices with 1024 microelectrodes into the brain tissue of five severely paralyzed patients, enabling basic "brain control" functions [2] Group 2: Clinical Applications - A 52-year-old male patient with paralysis from multiple strokes successfully implanted CorTec's BCI chip, aiming to enhance recovery through brain stimulation during rehabilitation [2] - The combination of implantable BCIs and artificial intelligence is expanding research fields and attracting more technological investment [2] Group 3: Ethical and Legal Challenges - The advancement of BCI technology raises significant privacy concerns, as it may allow access to personal thoughts, beliefs, and emotions [3] - Legal experts highlight the need for clarity on ownership of data collected by BCIs and the rights of users to modify or "hack" the implanted devices [3] - The potential for BCIs to not only read but also influence emotions poses questions about self-awareness and personal identity for users [4]
