Sounds convey emotions better than words.

25.01.2016

Scientists from Canada and the UK, led by Marc Pell (Marc Pell) from McGill University (Canada) proved that the human brain much faster recognizes emotions conveyed not by words, but by vocalizations - laughter, sobs, growls, sighs and the like. More evolutionarily ancient areas of the brain are involved in this process than in the interpretation of speech. Moreover, scientists have found that we pay much more attention to emotions expressed in such ways than when we are told about them in words.

It takes tenths of a second to process nonverbal signals about the emotional state. Such speed, according to the authors of the article, was developed out of necessity, since the life of an ancient person often depended on the rapid recognition of the emotions of another.

In the study, scientists focused on three main emotions - anger, sadness and happiness. 24 people took part in the experiment, all of them were given to listen to various non-verbal vocalizations, as well as phrases from words that did not exist in reality, spoken with different intonations. The task of the subjects was to find out the transmitted emotions, and using the EEG, the scientists established how quickly and in which areas of the brain the reaction was recorded.

As a result, several interesting conclusions were drawn. In addition to the fact that non-verbal sounds were evaluated faster, there was a difference in reactions to different types of emotions. Specifically, sounds associated with happiness, such as laughter, were processed faster than sounds associated with anger and sadness. At the same time, the reaction to anger has always been longer, that is, our brain pays more attention to this particular emotion, which, in general, is understandable from the point of view of evolutionary advantages.

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, ... >>

Schizophrenia-causing cells identified 26.05.2018

Schizophrenia is a very severe, devastating and widespread disorder. Genetic studies have linked hundreds of genes to schizophrenia, each of which contributes a small amount to the risk of developing the disease - such a huge number of experiments made it difficult to conduct experiments. Scientists needed to understand what binds these genes together and how exactly they affect the brain - diffusely to the whole or to separate parts.

It has been hypothesized that schizophrenia is based on several types of cells that affect different areas of the brain. In the course of the study, scientists were able to identify these types of cells.

"This marks a transition to where we can use large genetic studies to understand the biology of the disease. The results of this study give the scientific community the opportunity to focus their efforts where it will have the greatest impact," says Jens Hjerling-Leffler, head of the research team. in the Department of Medical Biochemistry and Biophysics at the Karolinska Institute, one of the main authors.

Now scientists are investigating the links between cell types and specific clinical features of schizophrenia. "For example, a large dysfunction in one cell type may reduce the likelihood of a positive response to treatment. And a dysfunction in another cell type may increase the chances of a long-term cognitive effect. This is important for the development of new treatments, since separate drugs may be required for each cell type," says co-author Patrick Sullivan.

Rapid advances in single cell genetics and transcriptomics have made it possible to study diseases in this way. The researchers suggest that in the near future, such a genetic approach will lead to a breakthrough in biological understanding and other complex disorders - such as autism, major depression and eating disorders.

"Understanding which cell types influence disease is critical to developing new drugs. If we don't know what causes a disorder, we can't study how to treat it," says Nathan Skene, a postdoctoral fellow in the Department of Medical Biochemistry and Biophysics. Karolinska Institute and the Institute of Neurology, University College London, one of the lead authors of the study.
