Artificial intelligence described the mechanism of human memory

Researchers at University College London (UCL) used an artificial intelligence to simulate the way our brain absorbs and remembers information. Human memory plays an important role in various cognitive processes; Learning about the world around you, reliving past experiences, and creating entirely 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, recent advances in artificial intelligence 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 different events.

Mechanism of human memory and artificial intelligence

The researchers used an artificial intelligence model in this study. They are approx 10 thousand Different pictures were shown to this artificial intelligence model to see how the neural networks remember these images. Each image was like a simple scene in a story.

Scientists actually wanted to study two parts of the human brain specifically; These two sections hippocampus And Neocortex have names The hippocampus is an important part of the brain that plays an essential role in the formation and consolidation of memories and spatial orientation. The neocortex is also responsible for the neural computations of attention, thought, perception, and episodic memory.

In this study, the artificial intelligence 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 identified important parts of each scene, such as the arrangement of walls and objects, so that the “brain” could remember old scenes and render completely new ones. This helps the brain to be efficient because it doesn't have to keep every little detail in memory, but can focus on things that are unique or different in each situation.

This study shows that when we review memories while resting, our brains understand patterns of past experiences. This is important 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 intelligence how our brain learns from experiences, remembers them and uses this knowledge to imagine new things or plan for what happens next.
