Several studies point to an important function of cyclooxygenase (COX) and prostaglandin signaling in models of synaptic plasticity which is associated with N-methyl-D-aspartate receptors (NMDARs). Cyclooxygenase gene is suggested to be an immediate early gene that is tightly regulated in neurons by NMDA dependent synaptic activity. Nonsteroid Antiinflammatory Drugs (NSAIDs) exert their antiinf...

Objective(s): In addition to genetic factors, environmental phenomena during postnatal age highly affect development and, in turn, function of the brain. The present work evaluates if morphine consumption during lactation period influences the spatial performances and synaptic plasticity in rats at neonatal period of age. Materials and Methods:</stron...

Ca(v)2.1 channels (P/Q-type) play a prominent role in controlling neurotransmitter release. Transgenic mice in which the α1A pore-forming subunit of Ca(v)2.1 channels is ablated (KO) provide a powerful tool to study Ca(v)2.1 function in synaptic transmission in vivo. Whole-cell patch clamp was used to measure inhibitory glycinergic postsynaptic currents (IPSCs) from the lateral superior olive (...

To study the effect of organic Se on spatial learning and memory deficits induced by Pb exposure at different developmental stages, and its relationship with alterations of synaptic structural plasticity, postnatal rat pups were randomly divided into five groups: Control; Pb (Weaned pups were exposed to Pb at postnatal day (PND) 21-42); Pb-Se (Weaned pups were exposed to Se at PND 43-63 after P...

Organometal halide perovskites (OHPs) exhibit great potential in memristors and artificial synaptic devices.

Traveling waves are commonly observed across the brain. While previous studies have suggested role of traveling in learning, mechanism remains unclear. We adopted a computational approach to investigate effect on synaptic plasticity. Our results indicate that facilitate learning poly-synaptic network paths when combined with reward-dependent local plasticity rule. also demonstrate expedite find...

Ca(v)2.1 channels, which conduct P/Q-type Ca(2+) currents, were expressed in superior cervical ganglion neurons in cell culture, and neurotransmission initiated by these exogenously expressed Ca(2+) channels was measured. Deletions in the synaptic protein interaction (synprint) site in the intracellular loop between domains II and III of Ca(v)2.1 channels reduced their effectiveness in synaptic...
