we have characterized stages in the posttranslational processing of the three neurofilament subunits , high ( nf-h ) , middle ( nf-m ) , and low ( nf-l ) , in retinal ganglion cells in vivo during the interval between synthesis in cell bodies within the retina and appearance of these polypeptides in axons at the level of the optic nerve ( optic axons ) .
