The effect of ketamine on synaptic transmission and synaptic plasticity in CA1 area of rat hippocampal slices
The effect of ketamine (1-100 µM), which has NMDA receptor antagonist properties, on synaptic transmission and long-term potentiation (LTP) in CAl area of rat hippocampus was examined in vitro. Field potentials were recorded in pyramidal cell layer following Schaffer collateral stimulation. Primed-burst stimulation (PEs) was used for induction of LTP. The amplitude of population spiks (PS) was ...
متن کاملGlycine receptor activation regulates short-term plasticity in CA1 area of hippocampal slices of rats.
Functional glycine receptors (GlyRs) are enriched in the hippocampus, but their roles in synaptic transmission are unclear. In this study, we examined the effect of GlyR activation on paired-pulse stimulation of the whole-cell postsynaptic currents (PSCs) in the Schaffer-CA1 synapses in rat hippocampal slices. Bath application of glycine reduced the amplitude of PSCs, accompanied by an increase...
متن کاملSynaptic Plasticity: Short Term
Chemical synapses are rarely static transmitters of information between neurons. Their effectiveness waxes and wanes, depending on the frequency of stimulation and the history of prior activity. At most synapses, repetitive highfrequency action potentials (often called a tetanus) initially result in a rapid growth of successive postsynaptic potential (PSP) amplitudes, called synaptic facilitati...
متن کاملShort-term synaptic plasticity.
Synaptic transmission is a dynamic process. Postsynaptic responses wax and wane as presynaptic activity evolves. This prominent characteristic of chemical synaptic transmission is a crucial determinant of the response properties of synapses and, in turn, of the stimulus properties selected by neural networks and of the patterns of activity generated by those networks. This review focuses on syn...
متن کاملEnhancement of short-term synaptic plasticity by prior environmental stress.
All chemical synapses can rapidly up- or downregulate the strength of their connections to reshape the postsynaptic signal, thereby stressing the informational importance of specific neural pathways. It is also true that an organism's environment can exert a powerful influence on all aspects of neural circuitry. We investigated the effect of a prior high-temperature stress on the short-term pla...
