An animation toolbox for visualization of intracranial electroencephalography synchronization dynamics
This supplementary materials website accompanies the original article available here: http://dx.doi.org/10.1016/j.clinph.2016.03.001
The phase-synchrony indexed functional connectivity and eigenvector centrality are derived from iEEG recordings, filtered at 7 frequency bands during the 60 seconds prior to and during the ictal period of a representative seizure detailed in the text.
Blue lines represent a large increase in interelectrode synchronization relative to the interictal. Pink lines represents a large decrease in synchronization.
In the bottom right box, the translucent overlay is calculated from HFO amplitude.
Raw waveforms from representative electrodes (from top to bottom) outside, bordering, and within the clinical SOZ are shown at the bottom of the video, where the clinical seizure onset is denoted by the vertical dotted line.
This software is for research purposes only, and has not been validated for clinical use.
List of Functions
Calculates connectivity between all electrode pairs using a sliding window.
Loads iEEG data, overlays, grid electrode locations,
The main function that performs the rendering of the connectivity animation.
This function renders a single frame of the movie for saving high-resolution figures (typically for printing).
Displays the electrode grid overlaid on the operating room image to check alignment, and for other debugging purposes.
