The new method is validated on synthetic datasets and applied to EEG (electroencephalographic) data recorded in epileptic patients.  ...  From philosophers of ancient times to modern economists, biologists and other researchers are engaged in revealing causal relations.  ...  In a consecutive paper Hirata 13 propose majority voting of three causality detection methods (convergence cross mapping 5 , recurrence maps 12 and transfer entropy 3;14 ) to fill that gap, which seems  ...

Dynamic causal modelling of electrographic seizure activity using Bayesian belief updating

Gerald K. Cooray, Biswa Sengupta, Pamela K. Douglas, Karl Friston
<span title="">2016</span> <i title="Elsevier BV"> <a target="_blank" rel="noopener" href="https://fatcat.wiki/container/sa477uo7lveh7hchpikpixop5u" style="color: black;">NeuroImage</a> </i> &nbsp;
The scheme is tested on simulated and empirical seizure activity (recorded both invasively and non-invasively) and compared with standard Bayesian inversion.  ...  Seizure activity in EEG recordings can persist for hours with seizure dynamics changing rapidly over time and space.  ...  The method rests upon the assumption that the physiology of epileptic seizures takes place on at least two time scales.  ...
