FIG. 4.

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