阅读理解 Having a microchip implanted in a man's brain may be common in sci-fi movie plots, but it may soon become an actual possibility. Elon Musk -a US tech tycoon, founder of Space X- has been working on this technology. On Aug 28, Musk gave a display of the chip, which was implanted into the head of a pig named Gertrude. The chip, developed by Musk's company Neuralink, is the size of a coin. But don't let its size fool you. The tiny chip has over 3,000 electrodes (电极) attached to flexible threads, which can monitor about 1,000 neurons (神经元). It collects neural signals from an area of the brain, and then transmits those signals wirelessly to nearby computers, according to MSN. That enabled researchers to monitor Gertrude's brain activity while she was walking around in the display. Though the technology is still in its early stage, it is encouraging for humans. This technology would solve a lot of brain injuries and is essentia] for Al symbiosis, which will allow the human brain to combine with an artificial intelligence. When the device can be applied to humans, its main goal will be to help those who have mobility difficulties. Musk hopes this technology can also be used to help those with hearing and eyesight issues. Although such a device could repair those problems, putting it into practice is by no means a piece of cake. Currently, the device can transmit signals from about 500 neurons in the pig's brain. Compared to 80 billion neurons in a human brain, this number is tiny. And to cover the whole human brain also means the electrodes have to be much smaller. Also, implanting the chip into the brain poses a potential danger. There is a risk of the immune system attacking this foreign body. Right now, the hope of controlling the brain via controlling a few neurons seems overly optimistic. "There are many technological challenges ... to overcome before Neuralink can put its devices to the purposes," Yuan Lanfeng, an associate professor at the University of Science and Technology of China, told China Daily. （1） What do we know about Elon Musk's microchip?
