Problems solved by technology

[0003] Existing event-related potential test systems are all based on single or double stimulus (behavioral) event coding, and the method focuses on time-domain analysis, lacks multi-domain analysis functions such as frequency domain, time-frequency domain and space domain, and has simple functions or complex operations. It is difficult to meet the complex needs of experimental design and data analysis from the research and application fields

Embodiment Construction

[0019] The software of the neurobehavioral general testing system is based on the Windows XP / 2000 / NT operating system, which has a friendly interface and is easy to operate. The implementation process of using the system to record, acquire and analyze the visual P300 is given below.

[0020] First, use the multimedia stimulus-response subsystem to arrange and present two kinds of pictures. The interval between the two kinds of pictures is 1000 milliseconds, and they are arranged and presented 250 times in a random order to form the Oddball paradigm. Picture 1 with an appearance probability of 0.20 is the target stimulus. For their key press response, picture 2 with a probability of 0.80 is a non-target stimulus and no key press response is required. Various stimuli and responses use different values ​​as event codes. While recording behavioral indicators such as reaction time, the multimedia stimulus-response subsystem sends event information to the EEG / cognitive potential reco...

Abstract

An universal test system based on microcomputer for testing the nervous behaviour is composed of the irritation reaction multimedia subsystem and the cerebral current/cognitive level recording-analyzing subsystem, both of which are connected via serial communication parts. The former can make the video-audio irritation its ns precision, record the reaction of the person to be tested, and send outrelative event. The latter is composed of 5 functional modules (data acquisition, cerebroelectric wave classification, average superimpose, total average and multi-domain analysis) and digitalized cerebroelectric amplifier.

Description

technical field [0001] The present invention relates to a general test system for recording and analyzing human brain electricity (EEG), event-related potential (ERP; also known as "cognitive potential") and behavioral responses, which can be used to study advanced brain functions such as perception, attention, Memory, language, emotion, thinking and consciousness, etc., are also suitable for application fields such as medicine, psychology, education and justice. Background technique [0002] The EEG detected and recorded from the scalp has the advantages of high time resolution, cheap equipment, and portability for on-site use. Multi-electrode recording improves and makes up for the shortcomings of its low spatial resolution; combined with a stimulation system, it can extract reflections from the brain. Functional event-related potentials. [0003] Existing event-related potential test systems are all based on single or double stimulus (behavioral) event coding, and the me...
