4-channel computerized EEG
measurement and analysis system
4-channel EEG measurement and PC storage
Over 50 kinds of EEG analysis and preprocessing function (Real time support)
ERP (P300, N400) detection function
EEG-biofeedback function
Stimulus scheduling function (video, picture, text, music)
Real-time subject response key, event marking function
Timer, sampling frequency, number of channels, amplification can be selected
Providing library functions for developers
KFDA certified medical device product
4-channel EEG measurement and PC storage function
EEG of 4 regions can be measured at the same time and measured brain and data are stored in the computer
Quantitative EEG analysis function
Dozens of basic analysis methods that can extract the features of EEG are provided.
Power Spectrum Distribution
Absolute and relative power values of Delta, Theta, Alpha, Beta, Gamma area
Power values of segmented areas such as S-Alpha, F-Alpha, S-Beta, M-Beta, F-Beta
Percentage of power by each area such as Alpha/Beta, Theta/Beta
Cross-correlation analysis between the electrode pairs
MF, MEF, SEF Analysis
Mean, SD, Skewness, Kurtosis Analysis by the probability distribution
Average for all channels of the above analysis variables
Changing pattern of the above analysis variables over time
Event related evoked potential detection function
ERP can be extracted for composite stimuli such as randomly set shapes, characters, pictures as well as simple visual and auditory stimuli. In ERP, amplitude and latency of peak components such as N200, P200, N400, P600 can be analyzed
EEG-biofeedback function
Theta, Alpha, SlowBeta (SMR), FastBeta, Gamma, Alpha/Beta ratio, Theta/Beta ratio and Biofeedback are possible.
Stimulus scheduling function
A variety of EEG experiments can be designed because you can set so that experimental stimuli such as simple video, pictures, sentences, music etc. can be automatically presented at the time you want while measuring EEG.
Subject response key function
You can obtain the response information of the subject by the keyboard during EEG measurement.
Event Marking Function
If the subject fell asleep or moved seriously while measuring EEG, you can mark the event that happened in the envelope of the time.
Real time analysis function
You can check the results of EEG analysis immediately in real time as soon as measuring data.
Timer setting function
This is the function that measurement is conducted only for the time set by the user and then stored in a file.
This is the function required when studying EEG that must control the length of the data equally.
EEG preprocessing function
The preprocessing function that can be used for removing noise or trimming data is provided in the step of prior to analysis.
Selecting the analysis area corresponding to the desired channel, desired part
Extracting random vibration components by frequency filter
Extracting only areas marked with specific stimuli, certain response key according to the conditions
Cutting a specific area or substituting it with a different value
Resampling, Smoothing
Correcting values beyond a certain range
Converting monopolar into desired bipolar signal
Providing library functions for developers
Without knowledge of the hardware, you can directly control equipment within applications developed by the researcher and
obtain EEG data in real time to use them for the research purpose.
Others
Sampling frequency, amplification degree, number of measuring channels can be randomly adjusted.
