Structural organization of the glomerulus in the main olfactory bulb.

According to the combinatorial receptor and glomerular codes for odors, the fine tuning of the output level from each glomerulus is assumed to be important to the information processing in the olfactory system, which might be regulated by numerous elements such as olfactory nerves (ONs), various interneurons and centrifugal nerves. Recently structural and physiological analyses at the cellular level has started to reveal that the neuronal organization of the main olfactory bulb (MOB) might be more complex than previously believed. In this article we describe on some aspects of the structural organization of the glomerulus we have revealed in our morphological studies.
