Outline of Final Research Achievements |
The main olfactory bulb (MOB) is now one of the most interesting parts of the brain as an excellent model for understanding the neural mechanisms of sensory information processing and as one of the most prominent sites whose interneurons are generated continuously in the adult periods. The neuronal organization of the MOB is fundamentally important, but it still remains to be revealed. We focused on the following two issues; 1) the heterogeneity and peculiarity of dopamine-GABAergic juxtaglomerular cells (DA-GABA JG), and 2) the quantitative analyses of two subpopulations of juxtaglomerular neurons containing calcium binding proteins calretinin (CR) and secretagogin (SCGN). With regards to DA-GABA JG, some small to medium-sized neurons displayed the characteristics of so-called periglomerular cells with tuft-like intraglomerular dendrites, whereas the structural features of large neurons participating in the long-range interglomerular connections remain to be revealed.
