Splet01. jul. 2014 · One mechanism for this change is alteration of synaptic AMPA receptor (AMPAR) accumulation. Although decreased intracellular Ca 2+ levels caused by chronic inhibition of neuronal activity are believed to be an important trigger of synaptic scaling, the mechanism of Ca 2+ -mediated AMPAR-dependent synaptic scaling is not yet understood. Splet10. apr. 2024 · Both AMPA and NMDA receptors were double exponential models, and NMDA receptor model was more complex and had more dynamic behaviors than AMPA receptor model. For the inhibitory synaptic input, a model of GABA A synapse was applied with similar dynamics as the AMPA synapse, except that the parameters were adjusted …
