Figure 6.

Comparison of laminar distribution of different markers in the denervated tectum at 1 week postlesion. Cross sections through the dorsal tectum are shown (dorsal is up). Tenascin-R (A, B), tyrosine hydroxylase (C, D), and serotonin (E, F) immunoreactivities show comparable distribution in wild-type and astray animals. However, labeling intensity of Tenascin-R and tyrosine hydroxylase was increased in astray mutants relative to wild-type animals. For anatomical abbreviations see previous figures. Scale bar, 100 μm.
