✦ Synopsis

Clusters of Ne. atoms (up to n = 90) formed in a supersonic nozzle expansion have been studied by electron impact ionization mass spectrometery. The Ne cluster mass spectra show the special stability of cluster ions with icosahedral structure (n = 13 and 55) confirming -despite previous discrepancies -the general validity of the sphere-packing principle. Neon cluster ions exhibit other magic numbers, e.g. at n = 2 1 and 75, not common to all of the other rare gases.

## Abstract Paranodal axo‐glial junctions are important for ion channel clustering and rapid action potential propagation in myelinated nerve fibers. Paranode formation depends on the cell adhesion molecules neurofascin (NF) 155 in glia, and a Caspr and contactin heterodimer in axons. We found that
