Renowned American entrepreneur Elon Musk announced on the 29th that his brain computer interface company, Neuro Connect, conducted the first human transplant of a brain computer interface device on the 28th, and the transplant recipient is currently recovering well. According to Musk, Neuro Connect's first brain computer interface product is called "telepathy". After the brain is implanted into a device, it can control phones and computers with just mind, and control almost all devices through them. The population who have lost limb function will be the first users of this product. What kind of technology is brain computer interface? What are the future application prospects? On July 6, 2023, Musk participated in the opening ceremony of the 2023 World Artificial Intelligence Conference held in Shanghai via video. Xinhua News Agency reporter Huang Xiaoyong photographed the revolutionary human-computer interaction technology "Brain Computer Interface". It is a revolutionary human-computer interaction technology that works by collecting neural signals from the brain and analyzing them to convert them into specific instructions. This technology can create a direct connection between the human or animal brain and external devices, without relying on normal output pathways composed of peripheral nerves and muscles, achieving direct information exchange between the brain and the machine. At present, brain computer interface technology is divided into three categories based on whether it needs to invade the brain and the degree of invasion: non-invasive, invasive, and semi invasive. The products related to Neuro Connection Company are invasive. The important functions of brain computer interface devices include helping to treat memory decline, cervical spinal cord injury, and other neurological diseases, helping patients with motor dysfunction, paralyzed individuals recover their ability to communicate with the outside world, and even re walk, improving and enhancing their quality of life. With the development of brain computer interface technology, its potential application scenarios in both medical and non-medical fields are constantly expanding, including monitoring and evaluating brain status, regulating nerves, enhancing sensory abilities, improving game controllability, as well as in fields such as education and military. According to Musk, the first users of this product will be people who have lost limb function. Imagine Stephen Hawking's communication speed might be faster than that of a typist or auctioneer (if implanted with a brain computer interface device). That's our goal. What are the future application prospects? Musk's "Neural Connection" company was founded in 2016, focusing on the development of implanted brain computer interface devices. In August 2020, Musk livestreamed an online demonstration of a pig whose brain was implanted into a brain computer interface device, and its brain activity signals could be read in real-time. The piglets implanted in the brain and then removed showed no difference in health compared to ordinary piglets. The picture shows Musk attending an event in Australia on September 29, 2017. The effective detection of brain neuron related potentials plays an important role in neural signal processing. Musk said that preliminary results indicate that implantable brain computer interface devices have promising prospects for detecting neuron related potentials. According to American media reports, in addition to Neuro Connect, there are also several American companies developing brain computer interface technology. The potential functionality of brain computer interface devices is powerful, but the safety of their implantation into the human body has always been controversial and concerning
