AIM To investigate the effects and mechanism of succinic acid on pentylenetetrazol (PTZ) chemical kindling and amygdala electrical kindling in rats. METHODS PTZ chemical kindling and amygdala electrical kindling models were established in rats. The effects of succinic acid on the behavior and afterdischarge of kindled rats were observed. The mice were pretreated with succinic acid, 30 min lat...

introduction: although hippocampus is the most famous brain area involved in temporal lobe epilepsy, hippocampal kindling (hk) develops very slowly. hence, rapid kindling is usually preferred to the traditional kindling and it is widely used. in this article we aimed at finding the optimal stimulus pattern, which yields the fastest hk rate. methods: stimulus patterns with different duration (2,...

Background: The interaction between antiepileptic drugs and brain electrical stimulation is a potential therapy to control of seizures in patient with pharmacoresistance to drugs. So, the aim of present study was designed to determine the effect of a sub effective dose of sodium valproate combined with low-frequency electrical stimulation during kindling. Material and Methods: One tripolar ele...

The effect of electrical kindling, applied twice daily in primary auditory cortex on the neural response properties and tonotopic organization in the lightly ketamine anesthetized cat is presented. Kindling refers to a highly persistent modification of brain functioning in response to repeated application of initially sub-convulsant electrical stimulation, typically in the limbic system but her...

Repeated alcohol withdrawal has been shown to kindle seizure activity. The purpose of the present investigation was to study electrical amygdala kindling in rats previously exposed to alcohol-withdrawal kindling. In three independent experiments, male Wistar rats were subjected to multiple episodes each consisting of 2 days of severe alcohol intoxication and 5 days of alcohol withdrawal. In the...

A variety of animal models have been developed to study the effect of antiepileptic drugs. These models provide the means of inducing changes and causing alterations in neural function which may lead to epileptogenesis. Kindling is a lasting change in brain function caused by repeated stimulation resulting an increased seizure duration and progressive intensification of seizure activity. The ki...

In many alcoholics, the severity of withdrawal symptoms increases after repeated withdrawal episodes. This exacerbation may be attributable to a kindling process. Kindling is a phenomenon in which a weak electrical or chemical stimulus, which initially causes no overt behavioral responses, results in the appearance of behavioral effects, such as seizures, when it is administered repeatedly. Bot...
