Understanding the connectivity of the brain neural network and its evolution in epileptiform discharges is meaningful in the epilepsy researches and treatments. In the present study, epileptiform discharges were induced in rat hippocampal slices perfused with Mg2+-free artificial cerebrospinal fluid. The effective connectivity of the hippocampal neural network was studied by comparing the norma...

The study aimed to determine whether and how the activation of the acetylcholine receptor affects epileptiform discharges in the CA3 region in a rat hippocampus. Picrotoxin (100 μM), a GABAA receptor antagonist, was applied to a hippocampal slice to induce epileptiform discharges. The effects of the cholinergic agonist, carbachol, on the discharges were examined at the several concentrations (1...

objective neurodevelopmental disability is one of the most common problems of children referred to  pediatric neurology clinics. these children may suffer from speech delay, intellectual deficiency and behavioral disorder. some patients with neurodevelopomental delay, especially those with intellectual disability and speech problems, have abnormal electroencephalograms, without clinical seizure...

Mozart K.448 has been shown to improve cognitive function, leading to what is known as the Mozart Effect. Our previous work reveals positive effects of Mozart K.448 in reducing epileptiform discharges in epileptic children. In this study, we evaluated the effect of Mozart K.545 and compared the effects with those of Mozart K.448 on epileptiform discharges in children with epilepsy. Thirty-nine ...

Objective(s):Protective effects of diuretics, particularly of hydrochlorothiazide (HCT), for the development of seizure attacksepilepsy have been described in vivo. However, itsthe mechanism of action of HCT is unknownneeds to be elucidated. Materials and Methods: Extracellular field potentials were recorded from the CA1- and CA3-subfields of the hippocampus of rats. Epileptiform discharges wer...

Vigabatrin (VGB) may aggravate clinical seizures and epileptiform discharges especially in the patients with generalized epilepsy. This report is about the repetitive appearance of generalized spike-and-wave complexes in a patient with focal epilepsy. Though there were constant appearances of the generalized epileptiform discharges on the consecutive electroencephalograms (EEGs) taken over appr...

The purpose of this study is to determine regions of cerebral cortex activated during the onset and propagation of dense array electroencephalographic (dEEG) epileptiform discharges in patients with juvenile myoclonic epilepsy (JME), through the use of 256 channel, dense array scalp EEG recordings. Ten patients (16-58 years old) with the clinical diagnosis of JME comprised the study group. In a...

OBJECTIVE Corpus callosotomy tends to decrease seizure frequency and severity rather than transforming the seizure pattern from a generalized form into a lateralized or a partial one. The finding implies that bisection of the corpus callosum (CC) disrupts the epileptogenicity itself. In order to gain further insight into the possible role played by the CC in intractable generalized epilepsy, qu...

Transient stimulation of group I metabotropic glutamate receptors (mGluRs) induces persistent prolonged epileptiform discharges in hippocampal slices via a protein synthesis-dependent process. At present, the signaling process underlying the induction of these epileptiform discharges remains unknown. We examined the possible role of extracellular signal-regulated kinases (ERK1 and ERK2) because...
