Singing people feel the same as birds

01.01.2013

A bird listening to the singing of another bird experiences the same emotions as a person listening to music, scientists concluded as a result of a study published in Neuroscience.

"We found that humans listening to pleasant music and female birds listening to a male's song during the nesting season activated the same neural systems," says Sara Erk of Emory University. In males, hearing the song of another male, the reaction was different - the amygdala was activated, as happens in people who hear dissonant, unpleasant sounds.

Erk analyzed the results of studies that visualized the results of the nervous activity of a person listening to music. In addition, she reviewed bird brain maps from Money's lab, which uses songbirds as a model for studying neural structures in complex behavior. Some of the birds in the study were treated with hormones to encourage reproduction, while others were hormonally lowered. Outside of the breeding season, birds of both sexes used song to establish and maintain position in the flock. During the breeding season, the function of singing was different - males sang to attract females, as well as scare away other males.

The increase in male testosterone in response to someone else's singing indicated amygdala activity that correlates with the average person's response to bad music. The females, if their hormonal levels were high, clearly enjoyed the music. Those who did not enter the breeding season did not react in any way. Both of these phenomena are connected not only directly with a positive reaction to the "reward", but also with the mechanisms that regulate emotions. Both birdsong and music, according to Earl, activate ancient evolutionary mechanisms that are necessary for the reproduction and survival of the species.

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, ... >>

Imec Reference Antenna Module for 60 GHz Access Points 17.10.2018

To increase the volume of transmitted data, communication systems are beginning to conquer the millimeter wave band, in particular, the band around 60 GHz, which does not require frequency licensing to operate. He is open. Today, the 60 GHz 802.11ad standard is used to transmit data over very short distances (up to 10 meters, but in practice - almost close). For example, it turned out to be very relevant for headsets with immersion in virtual reality. A new 60 GHz 802.11ay standard is being prepared, which will expand the communication range from 10 to 300 meters. Also, the 60 GHz band can be used in 5G cellular networks to organize local subnets.

Phased antenna arrays (PAR) have been and remain one of the important components of millimeter-wave transceivers. The PAR can be used to control the antenna lobes, providing the maximum data rate over multiple channels with the best efficiency. In combination with RF power amplifiers, this is a rather expensive element of the transceiver system, which can be made cheaper with the help of unified reference modules. Pharrowtech, a business unit spun off from Imec as part of the institute's commercial incubator, has developed exactly such a module for distribution through OEM channels.

This is a module in the form of a compact active phased antenna array of 256 elements with 128 power amplifiers. The solution is assembled from "available" serial components and is presented as one of the most inexpensive among analogues. At the same time, the AFAR directivity angle is extremely wide, and the transmission range is unprecedentedly large. The solution is designed to create fixed access points for homes and service repeaters in the 60 GHz range to provide Internet to residents of rural areas, megacities and suburban areas.

Imec believes that 60GHz wireless technology will help close the need for high-speed digital communications even where cable Internet is offered. Deploying wireless points is faster and cheaper than laying cable, and moving to the 60 GHz band will solve the problem of increasing throughput.
