Tom Science and Technology News Scientists have identified brain regions that help us distinguish between good and bad. A recent comparative study shows that the thinking activities of human beings and robots are more similar than we originally thought, and they both adopt similar principles in the process of estimation and judgment.

Ben Seymour, from Britain, used a magnetic vibration imaging scanner to study the brain activities of 14 volunteers when they were learning how to distinguish between good and bad, right and wrong. After a painful electric shock to the back of the head, the subjects saw a random image and a certain combination, while other combinations were only accompanied by a less painful electric shock. After several experiments, subjects can subconsciously predict the wrong arrangement of interference. When they study, the key parts of their brains become excited. An exciting area is the insular cortex, which is traditionally thought to help deal with emotions and emotional problems. The other is called ventral striatum, which used to be considered as the power center of brain activity. However, this time, it was found for the first time that they were related to the ability to distinguish right from wrong.

This experiment is actually imitating the ability of human beings to form valuable judgments by using contradictory experiences.

The research team also mapped the brain activity on the tracer and mathematically described the basic process of the brain forming valuable judgments. By analyzing this model, scientists see that human beings show a way of learning from experience very similar to robots in this process. This result is surprising. In the process of robot learning, the signal of human brain almost matches the digital operation process completely. This shows that the working principle of human brain accords with the basic working principle of these intelligent artificial robots.

Some scientists think this is a "terrible experiment". At present, the most important thing is to conduct a comprehensive study in this field from neuroscience to engineering, from psychology to economics.
