Fig. 4.
CERN-874-immunopositive fibers in a section of the brain which is more caudal than the MPON. Bundles of fibers running towards the basal areas are observed (V, third ventricle). Bar: 100 μm. |

Fig. 6.
Cone-opsin labelling of the hypophysis. The neural lobe shows many cone-opsin positive fibers and axonal terminals. A higher density of fibers can be seen at the periphery. Note that the intermediate lobe (IL) and the anterior lobe (AL) of the hypophysis do not exhibit any IR (arrows point to some of the numerous Herring bodies). Bar: 100 μm. |

Fig. 8.
(A) and (B) represent two adjacent sections showing opsin and mesotocin (MT) IR, respectively. Note that the majority of the opsin-positive cells are also MT-labelled in the consecutive section (the black arrows point to these cells). Some exceptions (white arrows) show opsin, but not MT, immunostaining. Calibration bars: 50 μm. |
