The claustrum has been implicated in the kindling of generalized seizures from limbic sites. We examined the susceptibility of the anterior claustrum itself to kindling and correlated this with an anatomical investigation of its afferent and efferent connections. Electrical stimulation of the anterior claustrum resulted in a pattern of rapid kindling with two distinct phases. Early kindling inv...

introduction: epilepsy is a neural disorder in which abnormal plastic changes during short and long term periods lead to increased excitability of brain tissue. kindling is an animal model of epileptogenesis which results in changes of synaptic plasticity due to repetitive electrical or chemical sub-convulsive stimulations of the brain. lateral hypothalamus, as the main niche of orexin neurons ...

Effect of a triterpene isolated from the acetone soluble part of petroleum ether extract of R. cordifolia was studied on convulsions induced by maximum electro shock (MES), electrical kindling and various chemoconvulsants in rats and mice. The effect of triterpene was also investigated on behavior and gamma-aminobutyric acid (GABA) and serotonin (5-HT) content in mouse brain. Triterpene inhibit...

Low frequency stimulation (LFS) is a potential alternative therapy for epilepsy. However, it seems that the anticonvulsant effects of LFS depend on its target sites in the brain. Thus, the present study was designed to compare the anticonvulsant effects of LFS administered to amygdala, piriform cortex and substantia nigra on amygdala kindling acquisition. In control group, rats were kindled in ...

Electrical kindling refers to the seizure-generating properties of brain stimulation. In addition to producing epilepsy, the reorganization of forebrain neurocircuitry associated with kindling contributes to psychiatric disturbances involving fear and anxiety. The amygdala is a limbic structure that kindles readily and regulates the complex neurocircuitry underlying emotional responding. Dopami...

the n-methyl-d-aspartic acid (nmda) receptor is one of the specific types of ionotropic receptors which lied to glutaminergic system. it has been widely accepted that nmda receptor neurons promote anxiety, in humans as well as in animal models. however, in the previous study seems inhibiting of this receptors decreased the protective role in neural cell. demonstration of nmda receptor activity ...

Introduction: Electrical low-frequency stimulation (LFS) has antiepileptic effect, but the role of different stimulation parameters on this effect has not been determined. In this study the effect of different LFS parameters (intensity, pulse duration and train duration) on piriform-cortex kindled seizures was investigated. Methods: Seizure was produced in animals using kindling model of ep...

INTRODUCTION Epileptogenesis is a process of seizure development. Lamotrigine is a novel antiepileptic drug which is also used for antiepileptogenic research. Kindling models are recommended as potentially useful tools for antiepileptogenic treatment discovery. However, previous studies demonstrated that the antiepileptogenic effect of lamotrigine is controversial in the electrical kindling mod...
