Learning new things, we forget the old

25.03.2016

A group of scientists from Germany, Spain and Italy showed in experiments on mice that in the process of memorizing new information in the brain, new connections between neurons are simultaneously formed and existing ones are weakened.

Working with mice, neuroscientists studied the hippocampus, the region of the brain responsible for the formation of memories. Information enters the hippocampus via three different pathways, and the connections between neurons are strengthened as memories are consolidated. By blocking the main "path", the scientists found that the mice were no longer capable of learning, to form conditioned reflexes. But if the information was already learned before such a blockage, then the memories remained.

But something else was more surprising. The researchers found that connections along this blocked "path" weakened - this could not be affected by the blockage itself. The source of this weakening was found: it turned out that this happened at the time of the formation of new ties.

"One explanation is that there is a limited amount of space in the brain, so when you're learning, you have to loosen some connections to make room for others. To learn new things, you have to forget things you've learned before," he said. study leader Cornelius Gross.

Scientists believe that their discovery may be, in particular, the key to understanding how people forget traumatic events.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>
