Time course of dysregulation of calcium homeostasis in acutely isolated CA1 hippocampal pyramidal neurons after pilocarpine-induced Status Epilepticus
Glutamate induces excitotoxic damage to hippocampal pyramidal neurons in Status Epilepticus (SE) and epilepsy. In this study, we investigated time course of dysregulation of calcium homeostasis at various intervals after an episode of SE in acutely isolated CA1hippocampal pyramidal. For this purpose, male Sprague-Dawley rats (200 g) were subjected to pilocarpine-induced SE. The SE was blocked a...

متن کاملInhibition of dendritic spine induction on hippocampal CA1 pyramidal neurons by a nonsteroidal estrogen antagonist in female rats.
Estrogens regulate the formation of excitatory synaptic connections in the hippocampus of female rats. Because the adult hippocampus has a very low concentration of intracellular estrogen receptors, it is unclear whether a conventional genomic mechanism is involved. Nonsteroidal estrogen antagonists are useful tools to study estrogen action because they can provide pharmacological data in favor...
متن کاملEffects of resveratrol on intrinsic neuronal properties of CA1 pyramidal neurons in rat hippocampal slices
Introduction: Resveratrol (3,5,4-trihydroxystilbene) a non-flavonoid polyphenol found in some plants like grapes, peanuts and pomegranates, possesses a wide range of biological effects. Evidence indicates that resveratrol has beneficial effects on nervous system to induce neuroprotection. However, the cellular mechanisms of the effects are not fully determined. In the present study, the cellula...
متن کاملDistribution of slow AHP channels on hippocampal CA1 pyramidal neurons.
This work was designed to localize the Ca(2+)-activated K(+) channels underlying the slow afterhyperpolarization (sAHP) in hippocampal CA1 pyramidal cells. Cell-attached patches on the proximal 100 microm of the apical dendrite contained K(+) channels, but not sAHP channels, activated by backpropagating action potentials. Amputation of the apical dendrite approximately 30 microm from the soma, ...
