Description
Technical Field
The invention relates to the technical field of brain function state detection, in particular to a brain function state detection system based on memorial and electroencephalogram signal feedback.
Background
Electroencephalogram signals have been widely used in the study of the mechanism of the brains of memorial thought. Researches find that the electroencephalogram indexes sensitive to the proneness comprise alpha waves, theta waves and gamma waves. The frequency of the alpha wave is 8-13Hz. The higher amplitude on the dominant side is generally observed in the occipital region on both sides of the head. This wave occurs when the eyes are closed and relaxed; the a-wave disappears when the eyes are opened or an alarm (thought, calculation) is raised by any mechanism. Studies on alpha waves also found that training in the minds resulted in a significant increase in left-sided activity of the frontal alpha wave in normal individuals (Davidson al, 2003) and that this asymmetry of frontal alpha waves was also found later in the treatment of patients with depression. (Barnhofer et al, 2007) this is consistent with the lateralization of mood studies, i.e. positive mood more activates the left hemisphere, while negative mood more activates the right hemisphere. This suggests that the asymmetry of frontal waves caused by the belief may be one of the neural mechanisms that can improve the clinical effects of physical and mental health, subjective well-being, etc. of individuals.
The theta wave of the frontal area and the gamma change of the occipital area are also an electroencephalogram index capable of reflecting the memorial idea. The theta wave is a brain wave with a frequency between 4-8 Hz. It usually occurs when a person is in a state of deep relaxation, shallow sleep, meditation and subconsciousness. At the moment, the individual is easy to be implied, creativity and inspiration are sudden and rich in intuition, and learning and memory efficiency is improved.
The gamma wave frequency is above 35Hz, which is related to memory and overall thinking. A large number of researches find that the higher the individual belief experience level is, the larger the amplitude of gamma waves and theta waves is, the training condition of the belief can be judged through the brain function state based on the belief and electroencephalogram signal feedback, so that a training scheme is planned in a targeted manner to perform the belief training, and therefore the brain function state detection system based on the belief and electroencephalogram signal feedback is provided.
