Reverse Engineering of Human Brain Using EEG Recordings
摘要
In this study we investigate the possibility to use EEG recordings from the regions below the scull (i.e. the cortex) to reconstruct the mutual influence of various brain areas including deeper structures during conscious visual perception. For this aim a 3-dimensional spike timing neural network (SNN) model of the whole brain based on literature information was constructed. The EEG data measured before the performance of a visual task (i.e. before visual stimulation) was fed to the positions of electrodes as input currents and all connections within the designed structure were allowed to change via spike-timing dependent plasticity (STDP) rule in order to tune the model connectivity. Next the EEG recordings during consecutive visual stimulation were fed to the tuned model and spike timing activity of the regions around the EEG electrode positions was recorded and analyzed. The results are discussed with respect to the known by far theories of conscious visual perception.
