- Petrosal anatomy in the fossil mammal Necrolestes: evidence for metatherian affinities and comparisons with the extant marsupial mole.
- Ladevèze S1, Asher RJ, Sánchez-Villagra MR.Author information 1Palaeontologisches Institut und Museum, Universität Zürich, Zürich, Switzerland.AbstractWe present reconstructions of petrosal anatomy based on high-resolution X-ray computed tomography scans for the fossil mammal Necrolestes and for the marsupial mole Notoryctes sp. Compared with other mammals, Necrolestes exhibits a mosaic of plesiomorphic and derived characters, but most of the evidence supports its metatherian status. We revised previous descriptions and report on features of phylogenetic or functional significance. Necrolestes exhibits features that support metatherian affinities, such as the presence of a short and lateral prootic canal, and the loss of the stapedial artery in adults. A deep groove at the anterior pole of the promontorium is present in front of the cochlear housing, a variant on the extrabullar pathway of the internal carotid artery. The promontorium is laterally bordered by a large bony projection resembling the eutherian tegmen tympani [De Beer GR (1937) The Development of the Vertebrate Skull, Oxford, Clarendon Press, p. 391]. Posteromedial to the secondary facial foramen and anterolateral to the fenestra vestibuli is a pronounced fossa for the tensor tympani muscle. On the medial part of the pars canalicularis there is a great inflation of the medial side of the caudal tympanic process, a structure of unknown function. The internal acoustic meatus exhibits a broad transverse septum and is bordered laterally by a broad prefacial commissure. The cochleae of Necrolestes and of Notoryctes have fewer spiral turns (1.1 and 1.6, respectively) than most marsupials. The lateral semicircular canal is more expanded than the posterior semicircular canal in Necrolestes but not in Notoryctes. Both Necrolestes and Notoryctes have a second crus commune, i.e. the lateral semicircular canal opens into the ampulla of the posterior semicircular canal. A stylomastoid foramen enclosed anterodorsally by both the pars cochlearis and pars canalicularis is present in Dasyuridae, Dromiciops gliroides and Notoryctes.

- Protein S100 immunoreactivity in glial cells and neurons of the Japanese quail brain.
- Castagna C1, Viglietti-Panzica C, Carlo Panzica G.Author information 1Department of Veterinary Morphophysiology, University of Torino, Grugliasco, I-10095, Torino, Italy.AbstractIn mammals, sparse data illustrated the neuronal expression of S100 protein in central and peripheral nervous system. Similar studies have not been performed in other vertebrate species, in particular in birds. We provide here a detailed description of the distribution of the calcium-binding protein S100 in neuronal and glial elements in the central nervous system of an avian species, the Japanese quail (Coturnix japonica) largely used for neuroanatomical and functional studies. The distribution of S100-like immunoreactivity was analyzed by three different antisera: a polyclonal, against S100 protein, and two monoclonals, against the beta-subunit (S100beta) and the alpha-subunit (S100alpha) of this protein. All sera showed glial positive elements, which were more abundant in the brainstem than in the prosencephalon. Moreover, the polyclonal and the monoclonal antibodies against the beta-subunit evidenced a neuronal population with a wide distribution, variable morphology and staining intensity. In the telencephalon and diencephalon a few S100-positive neurons were observed in basal ganglia, nucleus paraventricularis hypothalami, nucleus rotundus and nucleus geniculatus lateralis, pars ventralis. In the mesencephalon and pons a wide S100-immunoreactive neuronal population was detected in several regions, including motor and sensory nuclei of most cranial nerves (i.e. oculomotoris, abducens, trigeminus, cochlearis, trochlearis and vestibularis nuclei). This distribution appears very similar to that previously described in the rat hindbrain by both immunocytochemistry and in situ hybridization, as well as to sparse observations on different vertebrates. Therefore, our results suggest that the distribution pattern of this protein (both in glial and in neuronal elements) is highly conserved throughout the phylogeny.

- Distribution of NADPH diaphorase-containing neurons in the pigeon central nervous system.
- Atoji Y1, Yamamoto Y, Suzuki Y.Author information 1Laboratory of Veterinary Anatomy, Faculty of Agriculture, Gifu University, Yanagido 1-1, Gifu 501-1193, Japan. atozi@cc.gifu-ac.jpAbstractThe aim of the present study was to determine the distribution of nitric oxide-synthesizing neurons in the pigeon brain and spinal cord. Tissue sections were stained for reduced nicotinamide adenine dinucleotide phosphate-diaphorase (NADPH-d). In the telencephalon, intensely stained neurons with dendrites extending distally were seen in most regions. The ectostriatum was characterized by intensely and diffusely stained neuropil. In the diencephalon, intensely positive neurons were seen in the lateral hypothalamic region and lateral mammillary nucleus. In the mesencephalon, intensely stained, multipolar neurons were abundantly scattered in the central gray, nucleus intercollicularis, reticular formation, nucleus tegmenti pedunculo-pontinus, pars compacta, area ventralis of Tsai, and ansa lenticularis. In the rhombencephalon, positively-stained neurons were found in the pontine nuclei and reticular formation. The cerebellar cortex, except for Purkinje cells, was a preferential region for NADPH-d activity. Positive end-bulbs made contact on somata in the nucleus magnocellularis cochlearis. In the spinal cord, NADPH-d positive neurons were seen in layer II and the marginal nucleus. Our results demonstrated that the distribution of NADPH-d-containing neurons in the pigeon brain and spinal cord is more complex than in other avian species. Our findings indicate that NADPH-d-containing neurons are present in several sensory pathways, including olfactory, visual, auditory, and somatosensory tracts, although some nuclei in each system did not show NADPH-d activity. The wide distribution of NADPH-d activity in the pigeon CNS suggests that nitric oxide modulates sensory transmission in avian central nervous system.
