INTRODUCTION In kindling, repeated electrical stimulation of certain brain areas causes progressive and permanent intensification of epileptiform activity resulting in generalized seizures. We focused on the role(s) of glutamate and a negative regulator of glutamate release, STXBP5/tomosyn-1, in kindling. METHODS Stimulating electrodes were implanted in the amygdala and progression to two suc...

introduction: considering the antiepileptogenic effects of repeated transcranial magnetic stimulation (rtms), the effect of rtms applied during amygdala kindling on spontaneous activity of hippocampal ca1 pyramidal neurons was investigated. materials and methods: a tripolar electrode was inserted in basolateral amygdala of male wistar rats. after a recovery period, animals received daily kindli...

Kindling is discussed in relation to affective illness as a nonhomologous model, which shares the feature of increasing illness severity and evolution over time following repeated exposures to certain forms of stimulation. This progressive aspect of kindling has proven useful in the study of approaches to pharmacotherapeutics, mechanisms and characteristics of drug tolerance, and, most recently...

Objective: At present, there are many antiepileptic drugs with a wide range of side effects on the human body. It was assumed that Zataria multiflora Boiss (Z. multiflora) with sedative, anti-spasmodic and anti-inflammatory activity may be effective in the treatment of epilepsy. The aim of the present study was to elucidate the effect of Z. multiflora hydroalcoholic extract and its fraction ext...

Background and objectives: Most antiepileptic drugs that are commonly being used in the clinic have a wide range of unwanted side effects; while some species of pistachioshave been used in the traditional medicine to treat epilepsy. The aim of the present study was to investigate the anticonvulsant effects of the hydroalcoholic extract of Pistacia vera L. in p...

Conventional kindling experiments appear ideal for generating inadvertent conditioned effects: A variety of stimuli (e.g., removal from the home cage, attachment to the stimulation lead, and placement in the stimulation environment) are repeatedly presented to the animal prior to each stimulation and convulsion. We recently demonstrated that the stimulation environment can have a major impact o...

In previous studies, we reported that a single afterdischarge (AD) or repeated ADs (kindling) in the hippocampus resulted in schizophrenia-like behaviors such as hyperactivity and loss of sensorimotor gating. Given that medial prefrontal cortex (PFC) dysfunction is also found in models of schizophrenia, we hypothesized that a single AD in the PFC induces postictal hyperactivity, and PFC kindlin...

Syntaxin, a protein required for the docking of synaptic vesicles, may be involved in the manifestation of synaptic plasticity. The possible involvement of syntaxin in epileptogenesis was investigated by assessing the expression levels of syntaxin1B/GR33 mRNA by in situ hybridization at different stages of hippocampal kindling epileptogenesis and after the induction of generalized seizures. Den...

OBJECTIVE(S) A growing interest has recently been attracted towards the identification of plant-based medications including those with protective effects against cognitive impairment. Sesamol has shown promising antioxidant and neuroprotective effects, therefore, we aimed to evaluate its therapeutic potential in epilepsy which is commonly associated with oxidative stress and cognitive impairmen...
