The secret to a good sense of rhythm in musicians

14.09.2020

The ability to hit the beat turned out to be associated with the speed and degree of synchronization of the given rhythm and the rhythm of brain activity.

Researchers at McGill University in Toronto have studied how the synchronization of the brain waves of musicians with the rhythm of the audio recordings they listened to is related to the ability of the same musicians to reproduce a given tempo without error. The results of the work showed that this is what distinguishes a solid master from one who can "miss" past the beat. The ability to simultaneously listen and perform synchronized movements, such as in dance or when playing an instrument under a metronome, contains three levels of activity: listening, synchronization, reproduction.

In the experiment, 29 experienced musicians aged 18 to 30 listened to and reproduced different rhythmic patterns by tapping their fingers on the table. At this time, scientists measured their brain activity using an electroencephalogram. The first rhythm was a simple repetition of evenly spaced identical notes. The second, medium in complexity, was an alternation of high and low notes. The third rhythm, the most intricate, was the superimposition of four low notes on three high notes: the notes were evenly distributed in one measure.

It turned out that those participants whose brainwaves synchronized more accurately and faster with the rhythm track were better at identifying versions of rhythms with previously skipped notes. Also, these musicians more accurately reproduced the rhythm they heard: both at the same time as listening to the track, and from memory. The authors of the study emphasized that the degree of synchronization of brain waves with musical rhythm is a feature that can be trained, and the sense of rhythm can be “improved” by regularly practicing listening and reproducing rhythmic patterns.

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, ... >>

Handheld x-ray scanners 17.01.2013

Engineers at the University of Missouri have developed a compact X-ray source that is about the size of chewing gum. This development will create hand-held X-ray machines needed by doctors and security services.

Modern x-ray machines are too bulky and consume a lot of electricity. The new device is based on lithium niobate crystals, which have piezoelectric properties and act as voltage boosters. During the experiments, the new device was able to raise the voltage from 10 volts to 100 thousand volts. The lithium niobate crystal is an X-ray source: vibration energy is extracted in the form of a high-voltage electron beam, which is decelerated by a metal plate and produces X-rays.

The developers believe that in 3 years, based on the new technology, they will be able to create a compact X-ray machine, which is needed in many industries. A handheld X-ray scanner is useful for searching for defects in various designs, for examining luggage, on space technology, such as rovers. In medicine, portable x-ray machines are especially needed: imagine that dangerous radiation when taking a picture of a tooth will not be directed into the oral cavity, but vice versa - a “pill” emitter will be attached from the inside. It is possible that the power of the emitter can be increased hundreds of times, and then the military and special services will be interested in this invention, because the piezoelectric X-ray emitter will become a powerful secretive weapon that can kill a person.
