pubmed:abstractText |
After severance, axons can restore structural barriers that are necessary for recovery of their electrical function. In earthworm myelinated axons, such a barrier to dye entry is mediated by many vesicles and myelin-derived membranous structures. From time-lapse confocal fluorescence and DIC images, we now report that Ca2+ entry and not axonal injury per se initiates the processes that form a dye barrier, as well as the subsequent structural changes in this barrier and associated membranous structures. The time required to restore a dye barrier after transection also depends only on the time of Ca2+ entry.
