Researchers at University College London (UCL) used an artificial ielligence to simulate the way our brain absorbs and remembers information. Human memory plays an importa role in various cognitive processes; Learning about the world around you, reliving past experiences, and creating eirely new scenarios become possible for imagination and planning with memory. Now this research has better explained the mechanism of human memory.
According to a paper published in Nature, rece advances in artificial ielligence generative networks show how information can be extracted from experience to enable us to recall a specific memory and also to freely imagine what new experiences might be like. Recalling past memories takes place in the form of concepts, or more precisely, a combination of details stored in the brain and our expectations of what might have happened. The AI computational model used by the researchers can tell us how our brain perceives and remembers differe eves.
Mechanism of human memory and artificial ielligence
The researchers used an artificial ielligence model in this study. They are approx 10 thousand Differe pictures were shown to this artificial ielligence model to see how the neural networks remember these images. Each image was like a simple scene in a story.
Scieists actually waed to study two parts of the human brain specifically; These two sections hippocampus And Neocortex have names The hippocampus is an importa part of the brain that plays an esseial role in the formation and consolidation of memories and spatial orieation. The neocortex is also responsible for the neural computations of atteion, thought, perception, and episodic memory.
In this study, the artificial ielligence hippocampus network quickly learned each scene and replayed it; Then, in each replay, he transferred what he saw to the neocortex. The neocortex network, in turn, learned to reconstruct these scenes by organizing the information.
The model ideified importa parts of each scene, such as the arrangeme of walls and objects, so that the “brain” could remember old scenes and render completely new ones. This helps the brain to be efficie because it doesn't have to keep every little detail in memory, but can focus on things that are unique or differe in each situation.
This study shows that when we review memories while resting, our brains understand patterns of past experiences. This is importa because it helps us predict things like avoiding danger or finding food in the future; So in simple words, this study shows with the help of artificial ielligence how our brain learns from experiences, remembers them and uses this knowledge to imagine new things or plan for what happens next.
