Description

Brainwave painting system

The invention belongs to the technical field of application of brain waves, in particular to a system for visualizing brain wave activities.

Brain wave, brain magnetic wave and magnetic resonance imaging (MRI) are common techniques for recording brain information. Among them, brain wave recording has the longest history and is widely used. Brainwaves were discovered by German physician Hans Berger in 1924, but they did not become popular until more than ten years later. In the 1950s, it was widely used in sleep research, and became famous because of the discovery of rapid eye movement sleep.

When a person opens his eyes, closes his eyes, or is awake or comatose, the vibration frequency of his brain wave will change obviously, about 1~40Hz, the International Organization of Societies for Electrophysiological Technology according to different frequencies , The brain wave is divided into β, α, θ, δ and other waves. When people focus on thinking, reasoning, or stress, nervousness, uneasiness, and anxiety, it is easy to measure the beta wave (about 12~38Hz). The beta wave has the highest frequency and is a brain wave at the "consciousness" level. Beta waves can be divided into slow beta waves (about 12.5~16Hz), intermediate beta waves (about 16.5~20Hz) and fast beta waves (about 20.5~28Hz). After concentration, relaxation, wandering, emptying, absent-mindedness, and closing your eyes, an alpha wave (approximately 8 to 12 Hz) will be measured. The alpha wave can be said to be a bridge between "consciousness and subconsciousness." According to Hz, it can be divided into slow alpha wave (about 8~9Hz), intermediate alpha wave (about 9~12Hz) and fast alpha wave (about 12~14Hz). Once you go to sleep, the brain waves will change into low-frequency waves, theta waves (approximately 4-8 Hz) and delta waves (approximately 0.5-4 Hz). Theta waves are "subconscious" waves, such as memories, perceptions, emotions, attitudes, beliefs, dreams Or meditation; the delta wave is the "unconscious" level and is needed to restore physical sleep. The combined patterns of waves such as β, α, θ, and δ can reflect human behavior and mental state.

Based on the fact that brain waves can reflect human behavior and mental state, the brain wave characteristics are captured, and the brain wave signal characteristics are converted into instructions, and the computer or machine can be controlled according to human brain activities and ideas.
