Abstract

The interglomerular connections in the mouse olfactory bulb were examined with the retrograde-tracer experiments using Fluorogold. When the injections were restricted to the glomerular layer, we encountered tracer-labeled cells in the glomerular layer and the superficial part of the external plexiform layer, not only near the injection sites but also more than 500 microm distant from the injection sites. Almost of those tracer-labeled neurons distant from the injection sites were large tyrosine hydroxylase-positive juxtaglomerular neurons, some of which were confirmed to have intraglomerular dendrites. Thus, the long interglomerular connections were mainly made by a particular type of dopaminergic-GABAergic juxtaglomerular neurons.
