Clustering Approach to Quantify Long-Term Spatio-Temporal Interactions in Epileptic Intracranial Electroencephalography
نویسندگان
چکیده
Abnormal dynamical coupling between brain structures is believed to be primarily responsible for the generation of epileptic seizures and their propagation. In this study, we attempt to identify the spatio-temporal interactions of an epileptic brain using a previously proposed nonlinear dependency measure. Using a clustering model, we determine the average spatial mappings in an epileptic brain at different stages of a complex partial seizure. Results involving 8 seizures from 2 epileptic patients suggest that there may be a fixed pattern associated with regional spatio-temporal dynamics during the interictal to pre-post-ictal transition.

متن کاملQuantifying spatio-temporal dependencies in epileptic ECOG
There is evidence that the mechanisms leading to epileptic seizures can be understood by continuously tracking the ongoing spatio-temporal mappings in the brain. We propose to quantify the spatio-temporal dynamics by using a SOM-based Similarity Index (SI) measure. While it is shown that this measure is statistically as accurate as the original SI measure, it is also computationally faster and ...
متن کاملNonlinear analyses of interictal EEG map the brain interdependences in human focal epilepsy
The degree of interdependence between intracranial electroencephalographic (EEG) channels was investigated in epileptic patients with temporal lobe seizures during interictal (between seizures) periods. With a novel method to characterize nonlinear cross-predictability, that is, the predictability of one channel using another channel as data base, we demonstrated here a possibility to extract i...
متن کاملA new method for continuous ECG analysis using geometric algebra and fuzzy clustering
The aim of this paper is to describe a group of new and original algorithms to achieve robust and reliable analysis of long term ECG recorded in difficult situations (as in epileptic patients). To achieve robustness even when the signal is corrupted, available data from different leads (electrodes) are combined using some tools of recent mathematical methods based on Geometric Algebra and Calcu...
متن کاملInvestigation of Long Term Trend of Spatio-Temporal changes of Sea Surface Temperature in Oman Sea
Considering the vast application of sea surface temperature in climatic and oceanic investigations, this parameter was studied in Oman Sea from 1986 to 2015. The SST was surveyed using trend analysis and Global and local Moran’s I spatial autocorrelation. In trend analysis, the Mann-Kendall test was used to determine the trend of SST changes and the Sen's Estimator method was used to examine th...
