Glomerulus-Specific Synchronization of Mitral Cells in the Olfactory Bulb
Odor elicits a well-organized pattern of glomerular activation in the olfactory bulb. However, the mechanisms by which this spatial map is transformed into an odor code remain unclear. We examined this question in rat olfactory bulb slices in recordings from output mitral cells. Electrical stimulation of incoming afferents elicited slow ( approximately 2 Hz) oscillations that originated in glom...
متن کاملMembrane bistability in olfactory bulb mitral cells.
Whole-cell patch-clamp recordings were used to investigate the electrophysiological properties of mitral cells in rat main olfactory bulb brain slice preparations. The majority of mitral cells are bistable. These cells spontaneously alternate between two membrane potentials, separated by approximately 10 mV: a relatively depolarized potential (upstate), which is perithreshold for spike generati...
متن کاملStructural 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 ...
متن کاملThe mitral and short axon cells of the olfactory bulb.
A description is given of the mitral and short axon cells of the olfactory bulb of the rat from Golgi material examined with the light microscope and from material examined with the electron microscope. The mitral cells are large neurons with primary and secondary dendrites which both extend into the overlying external plexiform layer, although only the primary dendrite enters the glomerular fo...
متن کاملsynaptic organization of the glomerulus in the main olfactory bulb: compartments of the glomerulus and heterogeneity of the periglomerular cells.
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 for information processing in the olfactory system, which may be regulated by numerous elements, such as olfactory nerves (ONs), periglomerular (PG) cells, centrifugal nerves and even various interneurons, such as granule cells, making synap...
