An information-theoretic approach for studying synchronization phenomena in experimental bivariate time series is presented. "Coarse-grained" information rates are introduced and their ability to indicate generalized synchronization as well as to establish a "direction of information flow" between coupled systems, i.e., to discern the driving from the… (More)
| An information-theoretic approach for studying synchronization phenomena in experimental time series is presented and demonstrated in analysis of EEG recordings of an epileptic patient. Two levels of synchronization leading to seizures are quantiied and \directions of information ow" (drive-response relationships) are identiied.
The changes in density of inhibitory parvalbumin-immunoreactive interneurons were quantitatively studied by immunohistochemistry in a series of human neocortical samples comprising the spectrum of malformations of cortical development (MCD) encountered in epilepsy surgery and the non-malformed hippocampal sclerosis-temporal neocortex in patients with… (More)
Background and Aims. Deoxyribonuclease I (DNaseI) is an endonuclease that facilitates chromatin breakdown and promotes susceptibility to autoimmune disorders. The aim of current study was to investigate serum DNase I activity in patients with inflammatory bowel diseases (IBD). Patients and Methods. A cohort of 110 IBD patients was evaluated, aged 35 ± 12… (More)
The study provides a review of the basic examination procedures and results of proton magnetic resonance spectroscopy (1H MRS) in patients suffering from mesial temporal lobe epilepsy (MTLE). The source of seizures in MTLE is most often an epileptogenic focus secondary to hippocampal sclerosis. 1H MRS currently plays an important role in the non-invasive… (More)
Hippocampal sclerosis represents a common structural basis of temporal lobe epilepsy. However, the etiological factors and mechanisms leading to its development still remain unexplained. In our study, we present neuropathological findings in the resected hippocampus and the pole of the temporal lobe in 15 patients with hippocampal sclerosis. "Initial… (More)
