Long-term changes of the synaptic strength play a fundamental role in shaping the dynamics of neural networks and they are mainly linked to the variation of the number of bound phosphorylated AMPA receptors (AMPARs) at the postsynaptic site. In this project we will therefore investigate AMPAR-dynamics specifically considering interactions between different plasticity processes. We will develop a concise theoretical model describing the fundamental, plasticity-independent kinetics of AMPARs at the postsynaptic site divided into the postsynaptic density and the extrasynaptic membrane, and we will test it on data from this CRC.
