Summary of the master project:
Diffusive processes on curved surfaces are very relevant for cellular
processes and are increasingly used to characterize the behavior of
proteins in cell membranes. More specifically, neurotransmitter
are present in the cell membranes of neurons (nerve cells) and are
important for the signal transduction at synapses, which are the
specializations through which neurons communicate. The morphology of the
cell membrane at these synapses is non-trivial and this shape strongly
affects the receptor diffusion .
The typical shape of a single synapse and its impact on the diffusive
process has been studied [1,2]. An open question however is how this
affects the cross-talk between multiple synapses connected to the same
dendrite. In other words, how does the release of receptors in one
influence the concentration in neighboring synapses. To study this we
up a diffusion model that integrates the morphology of multiple
