Posterior lateral line nerve regeneration. (A, A′) Stitch reinnervation in 6-mo postfertilization fishes, 1 wk after nerve cut. The overall pattern of the original nerve branches (A) is reproduced by the regenerating axons (A′). Minor abnormalities in the path of nerve branches (B, arrow) are also reproduced after regeneration (B′, arrow). Small changes in the pattern of innervation within the stitch can be observed (B′, asterisks). More extensive departures from the normal branch pattern are occasionally observed in the more posterior region (C) and are also reproduced after regeneration (C′). (Scale bars, 300 μm.)
