The electrical oscillations we call brain waves have fascinated scientists and the public for more than a century. But it is still controversial whether they have functions or just represent the activity of the brain like the buzz of an engine. Many neuroscientists hypothesize that if brain waves have functions, they are also achieved through synchronous oscillation at different locations. However, as the research continues to deepen, researchers have discovered that many brain waves are actually "moving waves" that move like ocean waves. Now a research team at Columbia University in the United States has conducted a new study. Joshua Jacobs, a neurological scientist who heads the team, proposed that travel waves are very common in the human cortex and show varying degrees of organization according to the degree of performance of the brain performing tasks. This shows that brain waves are behavior-related and are in line with previous ...

There are about 100 billion neurons in the human brain. Any seemingly simple thing in an individual involves a large number of neurons involved in it. Of course, these neurons are highly orderly in activities, and the local field potential (LFP) in the brain that allows many neurons to move together is like a "trumpet" that directs neurons to work. Gamma oscillation is a relatively important type of local field potential in the brain, which is about 25-70 (average 40) Hz oscillation. Gamma oscillation was the earliest phenomenon reported by Wolf Singer, the Maxford Brain Institute in France in the 1980s.After discovering the DNA structure, Crick shifted his direction to the neurobiological basis of human consciousness. This gamma resonance signal is a phenomenon that Crick has always hoped to look for. He believes that consciousness is like music produced by neuronal resonance, it is an uninterrupted connection resonance across different brain re...

Digital therapeutics ( DTx) is a new medical technology concept that has emerged worldwide in recent years. It can be equivalent to conventional medicines and treatments , providing patients with evidence-based medicine-based disease management and treatment.

Researchers wonder if flash, pink noise, or some other non-invasive method can be used to train human brain waves and be used as a treatment for neurodegenerative disease?In March 2015, Li-Huei Tsai, a neurologist at the Massachusetts Institute of Technology (MIT), built a mini disco for her experimental mice in her lab. Every day, she would let these mice "hide" for an hour under the blurred lights of this "dance hall". These mice are Alzheimer's disease model mice, and their brains produce amyloid beta and plaques. This dance floor is a novelty for the mice, and they will all roam around curiously. After the experiment, Tsai performed anatomical observation on the mice and found that the plaques in the brain of the mice who went down the dance floor every day were significantly smaller than those of the mice who didn't (only stayed in a dark environment and were not stimulated by the dance floor light).According to Tsai, she repeatedly verified...

Since the mid-20th century, scientists have continuously explored neurophysiology and achieved remarkable achievements. Since Broca discovered language functional areas, psychologists have adopted the research paradigm of brain functional areas.

1, alpha alpha wave (α wave)This frequency range fills the gap between our conscious mind and our subconscious mind. In other words, alpha is the frequency range between beta and theta. It helps us calm down when necessary and promotes a deep relaxation feeling. If we become stressed, a phenomenon called "alpha wave blocking" may occur, which involves excessive beta activity and very few alpha waves. Basically, the test wave "blocks" the generation of the alpha wave because we become too excited.Frequency range: 8 Hz to 12 Hz (medium)Too many: daydreaming, unable to focus, too relaxedToo little: anxiety, high stress, insomnia, obsessive-compulsive disorderBest: RelaxIncreased alpha waves: alcohol, marijuana, relaxants, some antidepressants2, Beta wave (beta wave)These are called high-frequency low-amplitude brain waves and are usually observed when we wake up. They involve conscious thoughts, logical thinking, and often have stimulating effects. ...

The core technology of brain wave frequency repair is brain-computer interaction technology. The early research of brain-computer interaction technology was intended to complete combat tasks such as remote control of robots through consciousness. Later, it gradually developed in medical fields, in order to find ways to cure physical rehabilitation such as movement and organ dysfunction through interdisciplinary research such as neuroscience, signal detection, and machine learning.Brain-computer interaction technology is divided into two categories: "implantable" and "non-implantable". Among them, the implant type is difficult to achieve and requires high accuracy and requires implantation into the brain skin. Non-implantation refers to the establishment of a new type of information exchange and control channel between the brain and the external environment, realizing physiological signal interaction between the brain and external devices. Brain-c...

Speaking of brain waves, everyone has heard of what kind of sound waves it is. If you express them in a short sentence, then this is equivalent to the rhythm of brain cell activity. In modern research, brain waves can actually be used as a way to treat the human body. For example, brain wave therapy means this. So where can brain wave therapy mainly work?Since the 1920s, humans have begun to pay attention to brain wave therapy, and then they have developed the benefits to the human body. In my country, this technology was introduced at the end of the last century, and now this brain wave therapy has begun to exist in large hospitals in various provinces and regions of my country. According to the principle, brain wave therapy actually uses special sound waves and light signals to cure various parts of the head at the same time, such as eyes, ears, mouth and nose, etc.When using these positions, it can massage and relax the human body, and this is...

Scientists study that when the frequency of biowaves is the same as the natural frequency of human molecules, resonance can occur. In the resonance state, the absorption energy value of the substance molecule reaches a peak. As a result of this strong absorption of energy, chemical bonds are easily broken, the human body's metabolism is accelerated, the atrophic cells are activated, and the compensatory cells return to normal. According to this principle, people in the era of information are likely to usher in the era of digital drugs, accurately calculate the cell resonance frequency, and use software to drive the transmission of biological waves to target the startup of cells to heal the body. This is a healthy treatment pipeline that can replace drugs and avoid the side effects of drugs due to poor selectivity. Bracelet physiotherapy instruments fundamentally work through a pipeline that balances the vibration frequency of human cells. Its eff...
