【嵌牛提问】HOW DOES THE NEURALINK SYSTEM DIFFER FROM OTHER BCI DEVICES?
【嵌牛正文】
There are currently only a few approved BCI devices that record from and/or stimulate the human brain, including devices for deep brain stimulation (DBS), which can treat neurological disorders such as Parkinson’s disease, and devices for the detection and disruption of seizures. These approved devices are designed to modulate neural activity over large brain areas, not to transfer information to and from the brain. Therefore, they generally have a small number of electrodes (less than 10), and these electrodes are much larger than our threads. For example, DBS leads have only 4-8 electrodes and are about 800 times larger in diameter.
There are also non-Neuralink BCI devices being tested in pilot clinical trials. However, none of these devices have more than a few hundred electrodes, and they are all either placed on the surface of the brain or in fixed arrays of single rigid electrodes. The Link is being designed with an order of magnitude more electrodes and with flexible threads that are individually placed to avoid blood vessels and to best cover the brain region of interest.
We are also designing the Link to provide unprecedented scale, with over 1024 channels of information from the brain. The Link is also being designed to perform real-time spike detection on every channel and to send this data wirelessly.
目前只有少数获得批准的 BCI 设备可以记录和/或刺激人脑，包括用于治疗帕金森病等神经系统疾病的深部脑刺激 (DBS) 设备，以及用于检测和破坏癫痫发作的设备。这些获批的设备旨在调节大面积大脑区域的神经活动，而不是将信息传入和传出大脑。因此，它们的电极数量一般很少（少于10个），而且这些电极比我们的螺纹要大得多。例如，DBS 导线只有 4-8 个电极，直径大约是其 800 倍。
还有一些非 Neuralink BCI 设备正在试点临床试验中进行测试。然而，这些设备都没有超过几百个电极，它们要么放置在大脑表面，要么放置在单个刚性电极的固定阵列中。 Link 的设计具有数量级更多的电极和单独放置的柔性螺纹，以避免血管并最好地覆盖感兴趣的大脑区域。
我们还在设计 Link 以提供前所未有的规模，拥有超过 1024 个来自大脑的信息通道。 Link 还设计用于在每个通道上执行实时尖峰检测并无线发送此数据。
