  • Functional Morphology: Synapse-, Receptor and Gap-junction distribution in identified STG Neurons

I examine network stability and functional aspects of neuron morphology in the stomatogastric ganglion (STG) of crustaceans. I am specifically interested in the structure of the neuropil, and the relative location of synaptic contacts, ion channels and receptors.

I am currently using a combination of electrophysiology and confocal imaging techniques to map the distribution of synapses and membrane proteins on identified neurons, which I then reconstruct after the experiment from high-resolution confocal image stacks (Figure1).

Figure 1: Dye fill of a pyloric neuron (yellow) in the STG and its synaptic contacts, labeled with an antibody against synapsin (magenta). Channel masking with a reconstructed surface of the filled cell was used to isolate synapsin-labeling in its processes (software: Imaris, Bitplane).
