Decrease in synaptic transmission can reverse the propagation direction of epileptiform activity in hippocampus in vivo.
Most types of epileptiform activity with synaptic transmission have been shown to propagate from the CA3 to CA1 region in hippocampus. However, nonsynaptic epileptiform activity induced in vitro is known to propagate slowly from the caudal end of CA1 toward CA2/CA3. Understanding the propagation modes of epileptiform activity, and their causality is important to revealing the underlying mechani...
متن کاملPropagation of low calcium non-synaptic induced epileptiform activity to the contralateral hippocampus in vivo.
Recent experiments show that non-synaptic epileptiform activity can be induced by high K+ and low Ca2+ solution in vivo in the hippocampal CA1 region when synaptic transmission is blocked. However, the ability of this type of epileptiform activity to propagate to other brain areas is unknown. Presumably, this epileptiform activity should propagate and project along the axons to remote brain are...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اول2-Arachidonoylglycerol enrichment Reduced Epileptiform Activity of the Rat Hippocampus induced with Pentylenetetrazol
Background and Objective: 2-arachidonoylglycerol (2-AG) and anandamide (AEA) are two major endocannabinoids. Using inhibitors of the enzymatic pathways involved in the elimination of 2-AG and AEA as well as synthetic 2-AG, we examined the effectiveness of these endocannabinoids on epileptiform activity induced in Wistar rats by pentylenetetrazol (PTZ). Material and Methods: Adult male Wistar r...
متن کاملLow-Calcium Epileptiform Activity in the Hippocampus In Vivo
Feng, Zhouyan and Dominique M. Durand. Low-calcium epileptiform activity in the hippocampus in vivo. J Neurophysiol 90: 2253–2260, 2003; 10.1152/jn.00241.2003. It has been clearly established that nonsynaptic interactions are sufficient for generating epileptiform activity in brain slices. However, it is not known whether this type of epilepsy model can be generated in vivo. In this paper we in...
