On August 13, 2008, scientists at the University of Reading in the United Kingdom unveiled the mystery of a robot powered by nerve cells. The robot, Called Gordon, has a brain stitched together from 300,000 cultivated mouse nerve cells. This landmark success shook the entire scientific community at once.
In the movie "Mechanical Enemy", why do tens of thousands of robots have advanced intelligence? It turns out that the brains of these robots are no longer the integrated circuit chips of the past, but are composed of neurons. As an intelligent control terminal, neurons, a life chemical, have an unrivaled advantage over traditional integrated circuits. In August 2008, the robot in "Mechanical Enemy" really became a reality - the world's first robot with a biological brain was unveiled, and its name was "Mitt Gordon". This groundbreaking experiment aims to explore the vanishing boundaries between natural spirituality and artificial intelligence, while revealing neurons, the most basic building blocks of memory and cognition.
At that time, the researchers took nerve cells from mouse embryos, washed them with enzymes and isolated them, and placed them in nutrient-rich medium. The medium is placed on a 60-electrode array of 8 cm long and wide. This "multi-electrode array" plays a role in connecting the living tissue and the machine, that is, the nerve cells send electrical pulses, and the living tissue is connected to the robot's body with the help of Bluetooth wireless devices, and the signals emitted by the sensors in the robot's body are received, so as to drive the robot to run without human control or computer remote control. Because the brain is living tissue, it must be kept at a constant temperature in a special temperature control box.
The designers tried to create intelligent robots that did not need preset programs, learned from setbacks, and could adapt to the environment on their own, and Gordon did not live up to expectations: 24 hours after the experiment began, the "brain" neurons of "Gordon" began to protrude synapses, test each other, and establish connections; After 5 days, the neurons spontaneously emit electricity and communicate. To a certain extent, "Gordon" can teach himself and gradually develop the habit of learning. To help "Gordon" accomplish this process, the researchers used different chemicals to enhance or inhibit neural pathways that are active during specific activities. Whenever a robot approaches an object, the signal stimulates the brain through electrodes. In response to stimuli, the brain outputs signals to control the robot's movements, thus avoiding hitting objects. It can be seen that the only thing that can control it is its own "brain".
This pioneering experiment, dedicated to the fusion of biological brains and robots, helps to unravel the mysteries of the human brain and helps to understand how the brain learns and remembers, with far-reaching scientific and medical significance!
