The present invention can use brain waves (EEG) to monitor the functional connectivity between cortical areas in real time which relates to functional cortical EEG-based real-time connectivity monitoring system, and more specifically relates to the mathematical modeling of real-time visualization of cortical functional connectivity possible EEG-based real-time monitoring system to calculate the connectivity of the brain's cortical surface rather than the surface of the head through . ; This invention is a real-time EEG monitoring connectivity information comprises a location detector for detecting location information for the EEG signal detection unit for detecting a brain wave, brain electrode and cortical model (anatomical boundary of the cerebral cortex) In the system, A / D conversion by having a converts the brain wave signal and receives the output from the detector into a digital EEG signal, the data collection unit for receiving the position information from the position information detector; The processing operation of the position information received from the data collecting unit through a linear estimation to generate inversion operator (inverse operator), separate the brain region to be observed by the cortical model received from the data collection unit preprocessor that; Fast Fourier transform unit FFT EEG signal in the time domain received from the data collection unit to convert the EEG signal in the frequency domain; And the fast Fourier transform output from the EEG signal part, using the inversion operator output from the pre-processing unit connectivity calculator to calculate the inter-region connectivity of the brain that are separated in the pre-processing unit; characterized in that it comprises a
