Neuralink, led by Elon Musk, demonstrates its brain-computer interface by enabling a quadriplegic patient to control a computer cursor and robotic limb using neuron spike decoding. The approach employs intracortical microelectrode arrays to translate neural activity into digital signals. Neuralink is also initiating 'Blindsight' trials to deliver camera-derived visual information directly to the visual cortex, aiming to restore partial sight.
Key points
- First Neuralink BCI enables quadriplegic patient to control cursor, shop online, and browse via thought.
- Latest trials demonstrate mind-controlled robotic arm manipulation in 3D space using neuron spike decoding.
- Vision restoration 'Blindsight' connects camera input to visual cortex, offering partial perception for blind patients.
Why it matters: Realizing thought-driven device control and sensory restoration through BCI marks a pivotal shift toward fully integrated neuroprosthetic therapies.
