Cognitive and EEG big-data system

Abstract

The invention relates to a cognitive and EEG (Electroencephalogram) big-data system including a data acquisition system, a storage system and a data analysis system, wherein the data acquisition system comprises an acquisition unit for data of cognitive behavior, an acquisition unit for EEG data, an acquisition unit for basic data, a data processing unit and a data transmitting unit; the storage system comprises a data receiving unit, a data storage unit and a database system; the data analysis system comprises a data service interface, a data analysis unit and a data access unit. The invention collects the cognitive-behavior data and the EEG data of all kinds of people, constructs a big-data system including the brain cognitive data, the EEG data and all types of data and archive information, and carries on the data analysis and data mining. It realizes the functions including the differential analysis of cognition ability, prediction and evaluation of cognitive development trend, effectiveness evaluation of cognitive ability training, EEG algorithm research, etc. It can be applied to evaluation, training, effect assessment and theoretical research of brain cognitive ability.

Description

technical field [0001] The invention relates to the technical fields of brain cognition, EEG and big data, in particular to a cognition and EEG big data system. Background technique [0002] Human cognitive ability refers to the ability of the human brain to process, store and extract information, usually including sensation, perception, information processing, attention, memory, spatial cognition, emotional ability, thinking, imagination, speech and other abilities. Traditional cognitive psychology research usually uses methods such as observation, survey, and experiment to carry out relevant research work, and it is difficult to touch the fields related to the neural mechanism of the brain. EEG is the electrical signal generated by the activity of hundreds of billions of neurons in the human brain. EEG activity is closely related to brain regions and brain states. EEG is an important means of understanding brain activity and cognitive processes. It can not only be used in...

Problems solved by technology

[0004] At present, the application of combining cognitive and EEG data is still limited to the academic research fields of cognitive neuroscience and cognitive psychology, and the scope of its experimental data collection is limited to a specific experimental plan, which has the advantages of small sample size and large data volume. Defects such as less content, narrow sampling coverage, poor randomness, lack of representativeness, etc.

[0005] There is currently no big data system that combines cognitive behavioral data and EEG data
