Synesthesia can be induced under hypnosis

20.12.2017

Synesthesia is a neuropsychiatric phenomenon when the type of stimulus and the type of sensations do not match, that is, the stimulus refers to one sense organs, and the sensations to others. Synesthesia has different types: for example, with color-graphic synesthesia, a person sees the image of letters or numbers in color, with musical-color music, music is perceived in the form of naturally and involuntarily manifested color spots, stripes, waves; in kinetic-auditory synesthesia, a person hears sounds by watching moving objects or flashes, even if they are not accompanied by any real sound.

At one time it was believed that synesthesia is either there or not. However, over time, it became clear that it can occur under the influence of various factors in people who have not had any synesthesia since birth. The factors can really be very different: from brain injuries and tumors to certain psychoactive substances and meditation. Researchers from the University of Turku have found that synesthesia is possible even under hypnosis.

The experiment of psychologists looked quite simple: it was necessary to name the colors of different geometric shapes - crosses, circles, squares, etc. The participants in the experiment were hypnotized and inspired that a specific color is characteristic of a certain figure (for example, a circle is always red, and a cross - blue). The volunteers were then taken out of hypnosis and asked to look at the figures.

Those who turned out to be especially sensitive to hypnosis did manage to merge color and symbol together, although everyone to a different degree (for example, one person did not have an unambiguous fusion of color and shape, but instead had difficulty identifying color in general - seeing colored crosses, circles and squares, he could hardly determine what they were painted in).

Other participants in the experiment who tried to reprogram their own perception without hypnosis, just by diligently thinking about green squares and blue crosses, did not experience any synesthesia. In other words, it was all about hypnotic suggestion.

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, ... >>

Nanowire networks learn and remember like the human brain 25.04.2023

An international team of scientists led by the University of Sydney tested the ability of a nanowire network to perform complex cognitive tasks that are characteristic of a complex nervous system. The analysis showed that networks that mimic the physical structure of the brain can learn and remember data.

To test their network, the scientists used a modified analog of the n-back problem. This is a popular experiment used in neurophysiology and psychology to evaluate memory. During the test, the subject, who is presented with a series of images (visual test) or names objects (hearing test), must indicate when this or that object was encountered n-steps ago.

For example, such a task may involve demonstrating a sequence of letters, and the person should be told when the same letter was encountered 1, 2, or more steps ago. The average score for most people on this task is 7. This means that most people can recognize the same image that appeared seven steps ago.

The researchers found that the nanowire network was also able to "remember" the desired endpoint in an electrical circuit seven steps back. "We manipulated the end electrode voltages to force the paths to change instead of letting the network just do its thing," explains Alon Loeffler, co-author of the study.

A series of experiments showed that under external influence, the nanonet "learned" and its memory "strengthened": the network memorized the paths proposed by the scientists, and over time, the existing connection did not decrease. This is reminiscent of the work of a synaptic network, scientists note, some connections are strengthened, others are weakened, and as a result, stable connections are formed in the learning process.

Nanowire networks are a type of nanotechnology, usually made from tiny, highly conductive silver wires. Invisible to the naked eye, particles coated with a plastic material are scattered in disorder to form a grid. Such wires, due to their properties, mimic the physical properties of the brain: a network of neurons connected via synapses.

The use of such networks opens up many real-world applications: for example, the creation of robotic devices and sensors that need to make quick decisions in unpredictable conditions.
