　　A study funded by the Medical Research Council and published in the journal identified a team of experts from Oxford University and Imperial College whose dorsal thalamus (MD) is involved in decision-making and learning. The place where we observe this brain area is called.

　　A senior author and PhD researcher from Oxford University explained: I understand that the dorsal thalamus is a field involving learning and decision-making, but I don’t fully understand its role. An important issue in neuroscience is how the brain performs computational functions, such as planning daily activities and deciding what to do for another thing. Since we use a variety of networks to process information in the brain, it is very useful to focus on the role of specific areas of the overall task. In this case, we decided to observe how the back of the thalamus supports the best processing of new learning and decisions.

　　This study used macaques to teach cognitive tasks on touch-screen computers to learn new information and make the right choices to release food rewards. These tests are repeated after surgery for selective injury induced by the dorsal thalamus.

　　Monkeys that do not use the dorsal thalamus rarely respond to changes. These changes require us to adapt to their behavior and continue to make the right decisions to maximize returns. When they make decisions with several different reward options, they will also struggle with their own decisions.

　　Dr.: Someone once thought that in this case, the monkey will continue to make the same choices as before, so the monkey can make different decisions, but the ability to integrate information from recent decisions is reduced. In the most recent decisions, they combined the latest choices to best guide the decision.

　　Research shows that the dorsal thalamus plays an important role in quickly integrating new information to learn some new knowledge and make decisions. This skill is essential for daily activities such as traveling by car and walking on busy streets.

　　Future research will help to understand the connection between the thalamus and other parts of the brain after acquiring new information, and how it depends on people's ability to learn, relearn, and adapt. Observe how it helps. The decision-making process.
