Elon Musk's brain chip: How it works2021|01:41
In a presentation posted to Neuralink's YouTube channel, Musk says the implant is 23 millimetres by 8 millimetres, and has electrode threads attached to it that are implanted into the brain.The implant is inserted by removing a piece of skull. It then sits flush with the skull, unnoticeable to others beneath hair.The implant works by monitoring neuron activity in the brain. The University of Queensland describes how neurons operate as a kind of electrical system. First, an electrical signal called an 'action event' is sent through one neuron.This triggers neurotransmitters to be released from that neuron's axon terminal into an area between two neurons. These are received by the dendrite area on the next neuron, which transforms them back into an electrical signal.
