| Outline of Final Research Achievements |
This research aims to establish structural basis for centrifugal regulation of synaptic circuit in the olfactory bulb, from our previously consistent studies with correlated laser and electron microscopy. We have paid special attention to serotonergic, cholinergic and noradrenergic neurons projecting to the olfactory bulb. These neurons have been examined by single-neuronal labeling as well as wide-filed laser/electron microscopic analyses, correlated laser and volume EM study. Results indicated interesting findings exhibiting layer-specific distribution by three kinds of centrifugal projections to the olfactory bulb. These findings have suggested more elaborate features of regulation of the synaptic circuit in the olfactory bulb than previously considered.
