操控睡眠,动物的记忆 z-bo 2020-08-19 474

　　Artificial memory may be produced during sleep, which is the conclusion of a research report published online by "Nature-Neuroscience". Studies have shown that when mice sleep, their brains can associate specific rewards with specific locations, and this association can cause the mice to wake up and produce corresponding behaviors.

　　has achieved the positioning cell is a type of cell found in the hippocampus of the brain, which is activated when the animal is in a specific location in the environment. When the animal sleeps, the activity pattern produced by these cells will "regenerate" again. It is believed that this behavior helps to integrate and enhance the cognitive map of the animal environment. Karim Benchenane and his colleagues stimulated the brain reward pathways of five sleeping mice, in which cells in the brain encode specific environmental locations. The other two mice received non-reward stimuli.

　　When they wake up, only mice that receive a reward stimulus related to cell activation at a specific location will spend more time in the location encoded by the cell. This indicates that artificial memory is formed when the mouse brain is at rest. Previous research has shown that the memory of the mouse can be manipulated. This study is the first to show that the memory of sleeping animals is manipulated by humans. However, it is not clear whether this memory manipulation can be done by humans.
