Figure 2. Examples of TPOH-ir and NK1R-ir neuronal staining.

Figure 2

A, typical plump, oval-shaped TPOH-ir neurones in raphé pallidus. B, narrow, elongated TPOH-ir neurones that extend along the ventral medullary surface. Bar = 100μm and applies to A and B. C, midline raphé TPOH-ir neurones that extend over the pyramids to the parapyramidal region at the level of the caudal facial nucleus. D, midline cluster of TPOH-ir neurones just dorsal to the pyramids at the level of the caudal facial nucleus. E, NK1R-ir neurones extending over the pyramids at the level of the caudal facial nucleus. F, NK1R-ir neurones clustered at the parapyramidal region just caudal to the facial nucleus. Bar = 100μm and applies to C–F.
