Description

Brainwave painting system

The invention belongs to the technical field of brain wave application, and particularly relates to a system for visualizing brain wave activity.

Techniques for recording brain information include brain waves, magnetic waves, and magnetic resonance imaging (MRI). The most ancient and widely used brain waves are recorded. Brain waves were discovered by the German physician Hans Berger in 1924, but they did not become widespread until more than a decade later. It began to be widely used in sleep research in the 1950s, and became famous because of the discovery of REM sleep.

When a person opens his eyes, closes his eyes, is awake, or is in a coma, the frequency of brain wave vibrations will vary significantly, between 1 and 40 Hz. The International Organization of Societies for Electrophysiological Technology follows different frequencies. Brain waves are divided into β, α, θ, δ and other waves. When people focus on thinking, reasoning, or stress, nervousness, uneasiness, anxiety, etc., it is easy to detect beta waves (about 12 ~ 38Hz), which have the highest frequency and are brain waves at the level of "consciousness". Beta wave can be divided into slow beta wave (about 12.5 ~ 16Hz), intermediate beta wave (about 16.5 ~ 20Hz) and fast beta wave (about 20.5 ~ 28Hz). After concentration declines, relaxes, wanders around, let go, absent mind, and closes eyes, alpha waves (approximately 8-12 Hz) will be measured. Alpha waves can be said to be a bridge between consciousness and subconsciousness. In addition, alpha waves are It can be divided into slow alpha wave (about 8 ~ 9Hz) and intermediate alpha wave (about 9 ~ 12Hz) according to Hz. And fast alpha wave (about 12 ~ 14Hz). Once in sleep, brain waves will become low frequency waves θ wave (about 4 ~ 8Hz) and δ wave (about 0.5 ~ 4Hz). Θ wave is a "subconscious" wave, such as memory, perception, emotion, attitude, belief, dream Or meditation, etc .; the δ wave is the level of "unconsciousness", which is needed to restore physical sleep. The combined pattern of β, α, θ, δ and other waves can reflect human behavior and mental state.

Based on brain waves that can reflect human behavior and mental state, brain wave characteristics are captured and brain wave signal characteristics are converted into instructions, which can control computers or machines based on human brain activities and ideas.
