This is a reflect Wang wrote after watching Tom Oxley’s TED Talk on “A Brain Implant That Can Turn Your Thoughts Into Text.”

  1. a) Why did you choose this topic? Why is it important to you? Answer in 2 sentences minimum

I am very interested in this technology. I also hope that I can use brain-computer interface in the future .

  1. b) Report on 5 interesting things that you learned in this talk. Each fact should have at least 2 sentences explaining it
  • They have found a new method to build a brain-computer interface, which does not cause physical rejection after implantation in the human body
  • The old brain-computer interface is attached to the brain in the form of electrodes, while the new brain-computer interface uses the interface built in the blood vessels inside the brain.
  • They use a more mature heart stent technology. They add some electrodes that transmit electrical signals to the heart stent. The wires are used to receive different responses in the blood vessels that extend everywhere in the brain.
  • This technique can be used for people who have ALS, strokes, loss of hand control but still functioning minds, if they want to do something they just need to consciously move their hands to do certain movements, (but In reality, they did not move) to achieve some operations
  • They observed and recorded the different electrical signals in the brain when people were doing some actions, and they could manipulate something when people did these actions again (even if they didn’t move)
  1. c) Reaction and  Concluding thoughts – min 5 sentences

This is a very promising technology. If it is successfully developed, it will definitely be used by many people in the future. Although this technology is not mature at present, the effect is only to do some simple operations.
