Scientists Found a Way to Get Rid of Memories
Memory is usually violated due to neurodegenerative disorders, accidents or serious stress. Scientists have been able to erase the associative memories in mice, suppressing the activity of a single gene in the brain. These results were achieved by neurobiologists from the Catholic University of Leuven in Belgium and the Leibniz Institute in Germany.
According to them, the memory is usually impaired due to neurodegenerative disorders, accidents or severe stress. However, they have shown that some of the memories can be removed if suppress the activity of a particular gene. For this purpose, neuroscientists have conducted experiments with genetically modified mice whose gene neyroplastin has been modified so that it can be turned off at specific times.
It is noted that the function of neyroplastin is only investigated by several research groups in the world. As shown, this gene is very important for the brain. For example, if a person's neyroplastin for any reason reduces its activity, it can lead to a reduction of mental abilities, and schizophrenia. During the experiment, scientists trained the mice to move from one end of the cell to another when the light signal is on. Thus the animals remembered that when the light is lit, then near the opposite wall the feed will appear.
Scientists call this as associative learning, and the best-known example is Pavlov's dogs who have a drooling whenever they hear the bell. When the mice learned to successfully carry out the test, the biologists turned off neyroplastin, and the animals were no longer able to solve this problem quickly and correctly. Scientists believe that it is absolutely amazing that switching off a single gene is enough to remove the memories formed before or during training. In future studies, neuroscientists are planning to see whether neyroplastin plays a role in the formation of other types of memory.
A major study from Harvard School of Public School finds that eating carbs in moderation, up to 50–55% of the diet, is the healthiest option. People who eat less than 40% or more than 70% carbohydrates had a higher risk of premature death. During the study, the...
