Needleman et al. examine the behavior of neurofilaments (NFs) in vitro in solutions containing different polyelectrolytes (i.e., in different salt solutions). In short, they found that the NFs formed hexagonal bundles in solutions with containing cations with a greater charge and larger size, while the NFs formed what the authors term "living necklace bundles" in solutions containing bivalent cations (Figure 1).
