Scientists from Japan were able to erase the memory from the brains of mice. The process of transferring the received information in the brain from short-term to long-term memory is called consolidation and allows you to fix any information coming from outside for a long time. In order for a person to forget any event, you just need to interrupt the consolidation process.
Scientists from Kyoto University in Japan have attempted to influence the brain optically using optogenetic techniques. The technique was tested on mice and allowed, according to scientists, to erase memories from the brains of animals.
The optical method of influence on the brain is based on the destruction of the protein cofilin, which ensures optimal functioning of neural connections – synapses. At the first stage of testing, an adenovirus was injected into the brain of experimental mice, which acted as a kind of “courier” delivering a protein associated with a fluorescent marker.
At the next stage, an optical effect was carried out, which initiated the release of oxygen that deactivates cofillin. As a result, scientists were able to carry out a local effect on the brain of experimental animals at a specific time. During the experiment, the temporal lobe of the brain of mice was irradiated twice. The first time immediately after the animal learned a new task, and the second time – during sleep immediately after the completion of the learning process. As a result, the complete loss of “memories” of the studied problem by the mice was recorded.
