Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Dream zone found in brain 23.04.2017

A large area of the posterior cortex changes its electrical activity as soon as we start dreaming.

Sleep is divided into several stages: REM sleep (REM sleep, or rapid eye movement phase) and non-REM sleep (which, in turn, consists of several more phases). For a long time it was believed that dreams come only in REM sleep - it’s not for nothing that the eyes move during it.

However, over time, it turned out that dreams are dreamed not only in REM sleep, but also in slow sleep (for example, a person may dream of something, although according to the electroencephalogram (EEG), he did not have any REM sleep at all).

Neuroscientists have long been trying to figure out whether dreams obey some laws, which areas of the brain turn on the dream mode, etc. Researchers from the University of Wisconsin-Madison write that they were able not only to find a region in the brain that “turns on” dreams, but also predict when a person will dream something. The experiment involved several dozen people who were asked to sleep in a laboratory with a small device for recording electrical brain waves on their heads. Volunteers were woken up at different times, asked if they dreamed anything and if they could remember any details of it, and their answers were compared with what the EEG showed.

It turned out that dreams have a well-defined electrorhythmic "handwriting": when a person began to dream about something, the intensity of low-frequency waves dropped, and the intensity of high-frequency waves, on the contrary, increased, and this happened in a certain area in the posterior lobes of the cortex. "Dream" changes in the electrical activity of the brain took place not only during REM sleep, but during non-REM sleep as well. By monitoring the “dream zone,” neuroscientists have been able to predict fairly accurately whether a person is dreaming or not. By the way, it turned out that dreams accompany 95% of REM sleep and 71% of slow sleep.

The area of the cortex associated with dreams turned out to be quite extensive, and in itself it consists of a number of areas with certain functions. The content of sleep depended on the area in which the electrorhythmic changes occurred: for example, if the intensity of high frequencies increased in Wernicke's zone, which is involved in the interpretation of speech, then the awakened person then told that someone was saying something in his dream.

For the time being, it would probably be premature to assert a causal relationship between dreams and the activity of the "sleepy cortex" - it may be that the change in the frequency of brain waves does not so much trigger the mechanism of dreams, but only accompanies it. One way or another, the more we know what happens in the brain during dreams, the more we will learn not only about the nature of sleep, but also about the nature of consciousness in general.
