In the Hollywood movie "The Ace of the Ace," the heroine is in the heartless clinic, eliminating all memory with the actor. Such scenarios may come true in the future. A new American scientific study pointed out that using mice experiments to find genes that can eliminate memory, replace unpleasant memories with good memories.
The team led by Cai Lihui, director of the MIT Institute of Learning and Memory at the MIT Institute of Technology in Taiwan, found that the Tet1 gene was the key to eliminating memory and played the role of eliminating memory in the process of replacing old memories with new ones. In the experiment, two batches of mice with and without Tet1 were put in cages for electric shock, and then put back in a while, but they were not turned on again. Afterwards, the Tet1 mice had not been afraid because their memory had been refreshed until they were shocked, but mice lacking Tet1 had Sustained fear. The study was published in the journal Neuron.
Cai Lihui said: "Eliminating memory is not deleting the original memory. The old memory informs the mouse that the cage is dangerous, but the newly formed memory will make it aware that it is actually safe here." The mice lacking the Tet1 gene cannot relearn experience and are trapped in In the old memory. The research team pointed out that if the activity of Tet1 gene can be enhanced, it will help develop new methods to treat patients with post-traumatic stress syndrome or addiction.
