Postnatally, the Purkinje cell degeneration mutant mice lose the main projecting neurons of the main olfactory bulb (OB): mitral cells (MC). In adult animals, progenitor cells from the rostral migratory stream (RMS) differentiate into bulbar interneurons that modulate MC activity. In the present work, we studied changes in proliferation, tangential(More)
Olfactory sexual dimorphism has mainly been described in the vomeronasal system, in relation to reproductive behavior, while evidence of sexual dimorphism in the main olfactory bulb (OB) remains scarce. There are no data indicating sex-related differences in the neurochemistry of intrinsic olfactory elements. Neurocalcin (NC) is a calcium-binding protein(More)
The rostral migratory stream is one of the few regions of the adult mammalian central nervous system in which cellular migration and proliferation have been described. Most rostral migratory stream cells divide rapidly and hence different proliferation markers have been employed to identify them. Nitrogen base substitutes, such as tritiated thymidine or(More)
The periglomerular cells (PG) of the olfactory bulb (OB) are involved in the primary processing and the refinement of sensory information from the olfactory epithelium. The neurochemical composition of these neurons has been studied in depth in many species, and over the last decades such studies have focused mainly on the rat. The increasing use of genetic(More)
Nicotine exerts its addictive influence through the meso-cortico-limbic reward system, where the striatum is essential. Nicotine addiction involves different neurotransmitters, nitric oxide (NO) being especially important, since it triggers the release of the others by positive feedback. In the nervous system, NO is mainly produced by nitric oxide synthase(More)
The Pax6 transcription factor is a key element along brain development in both the visual and olfactory systems. The involvement of Pax6 in neural fate is well documented in the visual system, whereas in the olfactory system, and in particular in the olfactory bulb (OB), its expression during adulthood has only begun to be elucidated. In the OB, the(More)
The dopaminergic system plays important roles in the modulation of olfactory transmission. The present study examines the distribution of dopaminergic cells and the content of dopamine (DA) and its metabolites in control and deprived olfactory bulbs (OB), focusing on the differences between sexes. The content of DA and of its metabolites,(More)
