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...

To test the hypothesis that repeated subconvulsive stimulations required to induce kindling can permanently alter gene expression of hippocampal neurons, we used Northern and in situ hybridization analyses to measure steady-state mRNA levels encoding several phenotypic proteins. mRNA encoding a membrane-bound protein, ligatin, was significantly reduced in kindled brains relative to naive and sh...

Double-pulse stimulation of the perforant path input to the dentate gyrus was used in the following experiments to produce paired pulse depression in that site. This effect provided an estimate of GABA-mediated recurrent inhibition. The depression was enhanced by drugs that facilitate or mimic GABA action and attenuated by drugs which block GABA transmission. Paired-pulse depression was signifi...

It has been suggested that expression of the immediate early gene c-fos links fleeting changes in neuronal activity to lasting modifications of neuronal structure and function in the mammalian nervous system. To test this idea, we examined behavioral and electrophysiological indices of kindling development and kindling-induced sprouting of hippocampal granule cell axons in wild-type (+/+), hete...

G-protein-coupled metabotropic glutamate receptors (mGluRs) are being implicated in various forms of neuroplasticity and CNS disorders. This study examined whether the sensitivities of mGluR agonists are modulated in a distinct fashion in different models of synaptic plasticity, specifically, kindling and chronic cocaine treatment. The influence of kindling and chronic cocaine exposure in vivo ...

The term kindling refers to the gradual development of epileptiform activity as a result of repeated, spaced stimulations of specific brain regions e.g. amygdala, hippocampus. cerebral cortex. Electrically kindled seizures are a valuable model of human complex partial epilepsy and evidence is accumulating for an involvement of excitatory amino acids (EAAs), and in particular glutamate. in this ...

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...
