Noradrenergic inhibition of synaptic transmission between mitral and granule cells in mammalian olfactory bulb cultures.
Noradrenergic modulation of the glutamatergic-GABAergic synapses between mitral/tufted (M/T) and granule cells has been implicated in some forms of olfactory learning (Brennan et al., 1990). Norepinephrine (NE) has been shown to disinhibit mitral cells (Jahr and Nicoll, 1982), but its site of action is not well defined. The effects of NE on synaptic transmission between monosynaptically coupled...
متن کاملDopaminergic neuromodulation of synaptic transmission between mitral and granule cells in the teleost olfactory bulb.
A growing body of evidence suggests that teleosts are important models for the study of neural processing of olfactory information, and the functional role of dopamine (DA), which is a potent neuromodulator endogenous to the mammalian olfactory bulb, has been one of the strongest focuses in this field. However, the cellular mechanisms of dopaminergic neuromodulation in olfactory bulbar neural c...
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 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...

20 A growing body of evidence suggests that teleosts are important models for the 21 study of neural processing of olfactory information, and the functional role of dopamine 22 (DA), which is a potent neuromodulator endogenous to the mammalian olfactory bulb, 23 has been one of the strongest focuses in this field. However, the cellular mechanisms of 24 dopaminergic neuromodulation in the olfact...
