During the past decade, several studies have demonstrated experimental evidence that temporal lobe seizures are preceded by changes in dynamical properties (both spatial and temporal) of electroencephalograph (EEG) signals. In this study, we evaluate a method, based on chaos theory and global optimization techniques, for detecting pre-seizure states by monitoring the spatio-temporal changes in ...

Let g ∈ Q be not −1 or a square. Let Pg denote the set of primes p such that g is a primitive root mod p. Let 1 ≤ a ≤ f, (a, f) = 1. Under the Generalized Riemann Hypothesis (GRH) it can be shown that the set of primes p ∈ Pg with p ≡ a(mod f) has a natural density. In this note this density is explicitly evaluated. This generalizes a classical result of Hooley.

OBJECTIVE To discriminate seizures from interictal dynamics based on multivariate synchrony measures, and to identify dynamics of a pre-seizure state. METHODS A linear discriminator was constructed from two different measures of synchronization: cross-correlation and phase synchronization. We applied this discriminator to a sequence of seizures recorded from the intracranial EEG of a patient ...

To test whether a prediction algorithm has any true predictive power, it is necessary to compare its performance with that expected under various well-defined null hypotheses. These null hypotheses must include the assumption that the prediction algorithm lacks any true predictive power. In the context of studies investigating the predictability of epileptic seizures, two approaches have been i...

21 A Matlab -based software package, EPILAB, was developed for supporting researchers 22 in performing studies on the prediction of epileptic seizures. It provides an intuitive and 23 convenient graphical user interface. Fundamental concepts that are crucial for epileptic 24 seizure prediction studies were implemented. This includes, for example, the development 25 and statistical validation of...

Background: Febrile seizure (FS) is one of the most common neurologic disorders in children. Electrolyte imbalance especially hyponatremia may have an important role triggering febrile seizure. The measure serum electrolytes will be useful predicting further seizures. This study aimed to investigate effect relative on risk recurrent Methods: prospective was performed 115 children (6-60 months) ...
