The ability to visualize the cells and proteins of a tissue within their original context (i.e., in vivo) is invaluable for the study of that biological system.

Current methods to assay protein-protein interactions, such as co-immunoprecipitation (Co-IP) and fluorescence resonance energy transfer (FRET), have limitations; for example, Co-IP is an in vitro technique and may not reflect the situation in vivo, and FRET typically suffers from low signal-to-noise ratio. The proximity ligation assay (PLA) is an in situ method for inferring protein-protein interaction with a high signal-to-noise ratio.

The ability to study the biology of glial cells is therefore critical for our ability to understand PNS biology and address PNS maladies. The genetic and proteomic pathways underlying vertebrate peripheral glial biology are understandably complex, with many layers of redundancy making it sometimes difficult to study certain facets of PNS biology.

The theoretical resolution limit of light microscopy is 200 nm in the -plane. Using stacks of images, 3D reconstructions of the -plane of a specimen can be achieved.

That finding contrasts with the view that myelin is a structural brake on plasticity, and that contributes to ending the critical period (CP) in the visual cortex (V1). Despite the evidence that myelin-derived signaling acts to end CP in V1, there is no information about myelin changes during adult plasticity in V1.
