FIG. 5.

Neo-Timm-positive regions: posterior CNS section—caudal rhombencephalon and spinal cord. Sequential representative slices (30 μm thick) showing caudal rhombencephalon (A) and spinal cord (B) regions. The whole areas were delimited and measured in optic density. Values are presented as the mean±SEM in arbitrary units (n=3–6). For abbreviations, see Table 1.
