Starlink in the Brain: Decoding the Human Super-Internet

The article draws an analogy between the Starlink satellite network and the neural network formed by the human brain's roughly 86 billion neurons and hundreds of trillions of synapses, outlining the speed of neuronal signal transmission (myelinated fibers can exceed 100 m/s) and the mechanisms by which this network "goes offline" in Alzheimer's disease and Parkinson's disease. It reviews cross-scale imaging methods including MRI, fMRI, fMOST, VISoR, and synchrotron X-ray imaging, and introduces the Neuralink demo of a monkey playing a game by thought as well as the first domestic clinical trial of an invasive brain-computer interface, completed in 2024 by Tsinghua University and Xuanwu Hospital.
