Transfer entropy reconstruction from electrophysiological data.

<p>Time resolved reconstruction of transfer entropy (TE) from magnetoencephalographic (MEG) source data, recorded during a face recognition task. (A) Face stimulus <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0102833#pone.0102833-Mooney1" target="_blank">[88]</a>. (B) Cortical sources after beamforming of MEG data (L, left; R, right: L orbitofrontal cortex (OFC); R middle frontal gyrus (MiFG); L inferior frontal gyrus (IFG left); R inferior frontal gyrus (IFG right); L anterior inferotemporal cortex (aTL left); L cingulate gyrus (cing); R premotor cortex (premotor); R superior temporal gyrus (STG); R anterior inferotemporal cortex (aTL right); L fusiform gyrus (FFA); L angular/supramarginal gyrus (SMG); R superior parietal lobule/precuneus (SPL); L caudal ITG/LOC (cITG); R primary visual cortex (V1)). (C) Reconstructed TE in three single subjects (red box) in three time windows (0−150 ms, 150−300 ms, 300−450 ms). Each link (red arrows) corresponds to significant TE on single subject level (corrected for multiple comparisons). (D) Thresholded TE links over 15 subjects (blue box) in three time windows (0−150 ms, 150−300 ms, 300−450 ms). Each link (black arrows) corresponds to significant TE in eight and more individual subjects (, after correction for multiple comparisons). Blue arrows indicate differences between time windows, i.e. links that occur for the first time in the respective window. (E) Experimental design: stimulus was presented for 200 ms (gray shading), during the inter stimulus interval (ISI, 1800 ms) a fixation cross was displayed.
