FIG. 4. Whole mount of the diencephalon and mesencephalon of tadpoles
(stage 51). (a) Retinal central pathways in a Xenopus tadpole.
All retina1 axons from the right eye were labeled with HRP to show
the projection to the visual centers, i.e., the optic tectum (OT), nucleus
Belonci (NB), corpus geniculatum thalamicum (CGT), and basal optic
nucleus (BON). OC: optic chiasm. For the method of HRP labeling,
see Fujisawa et ul. (1981). (b) The tadpole brain stained with MAb-A5
by the ABC method. The optic tectum, the nucleus Belonci, and the
corpus geniculatum thalamicum are positively stained. The staining
of the basal optic nucleus is obscure. (c) The tadpole brain stained
with MAb-B2 by the ABC method. All visual centers are negative
(X40). |
