Consciousness detection device for multi-sensory brain-body joint stimulations

Abstract

The present invention discloses a consciousness detection device for multi-sensory brain-body joint stimulations. The consciousness detection device comprises the following steps: constructing a non-invasive auditory and somatosensory joint stimulation normal form matched with a user consciousness function; collecting electroencephalogram and near-infrared brain blood oxygen data, and extracting characteristic responses of the brain to external consciousness related brain-body joint stimulation information; and conducting fusion analysis and extraction of electroencephalogram and cerebral blood oxygen of neurophysiological information and thus constructing a BCI system for micro-consciousness detection. The consciousness detection device conducts intensive induction of consciousness function responses of the brain, extracts electroencephalogram physiological and blood-oxygen multi-dimensional characteristics: event-related potential (ERP), steady-state somatosensory evoked potential (SSSEP) and blood oxygen concentration change, realizes a brain consciousness-oriented detection application, can be popularized to the fields of neuropsychology, life science and the like, and obtainsconsiderable social benefits and economic benefits.

Description

technical field [0001] The invention relates to the field of biomedical engineering, in particular to a consciousness detection device for multisensory brain-body joint stimulation. Background technique [0002] As a new type of human-computer information interaction technology, Brain-Computer Interface (BCI) can synchronously couple specific brain functions through external auxiliary equipment, induce and complete the external output of the brain's subjective intentions through repeated stimulation, and give full play to the patient's autonomic nerve regulation , and the visualization of its neural information makes the process of consciousness expression and the detection effect of functional state observable, quantifiable, and assessable, bringing new hope for the urgent needs of brain consciousness detection applications. [0003] At present, multi-sensory stimulation information represented by hearing, somatosensory, etc. can match the corresponding brain nerve function...

AI Technical Summary

Problems solved by technology

However, brain consciousness information is often difficult to capture or even ignored, and the traditional method of applying external stimulation modes has not seen consistent good results, and there is a lack of discussion on the neural function response and processing mechanism related to core brain consciousness

[0004] Although some neurocognitive psychology studies have found that the brain has a stronger response to the processing of multiple types of sensory stimuli than single sensory stimuli, there is still no consistent conclusion in the application of the BCI system, and in the application of microconsciousness detection There are no related reports in [3-5] , it is urgent to establish a new BCI system device for multisensory brain-body joint stimulation paradigm for brain consciousness detection
