Cannabinoid receptor-mediated regulation of neuronal activity and signaling in glomeruli of the main olfactory bulb.
Cannabinoid receptors (CB1Rs) are present in glomeruli of the main olfactory bulb. The functions of CB1Rs and their endogenous activators, endocannabinoids, for glomerular signaling are unknown. Glomeruli contain at least three types of neurons: periglomerular (PG), external tufted (ET), and short-axon (SA) cells. PG cells form inhibitory GABAergic dendrodendritic synapses with ET cells. ET cel...
متن کاملVital imaging of glomeruli in the mouse olfactory bulb.
We have monitored the pattern of identified glomeruli in the olfactory bulbs of newborn, juvenile, and adult mice over intervals of several hours to several weeks. Our purpose was to assess the development and stability of these complex units in the mammalian brain. Glomeruli can be observed by vital fluorescent staining and laser-scanning confocal microscopy without causing acute or long-term ...
متن کاملExternal tufted cells drive the output of olfactory bulb glomeruli.
Odors synchronize the activity of olfactory bulb mitral cells that project to the same glomerulus. In vitro, a slow rhythmic excitation intrinsic to the glomerular network persists, even in the absence of afferent input. We show here that a subpopulation of juxtaglomerular cells, external tufted (ET) cells, may trigger this rhythmic activity. We used paired whole-cell recording and Ca(2+) imagi...
متن کاملAnalytical Processing of Binary Mixture Information by Olfactory Bulb Glomeruli
Odors are rarely composed of a single compound, but rather contain a large and complex variety of chemical components. Often, these mixtures are perceived as having unique qualities that can be quite different than the combination of their components. In many cases, a majority of the components of a mixture cannot be individually identified. This synthetic processing of odor information suggest...
متن کاملControl of Mitral/Tufted Cell Output by Selective Inhibition among Olfactory Bulb Glomeruli
Inhibition is fundamental to information processing by neural circuits. In the olfactory bulb (OB), glomeruli are the functional units for odor information coding, but inhibition among glomeruli is poorly characterized. We used two-photon calcium imaging in anesthetized and awake mice to visualize both odorant-evoked excitation and suppression in OB output neurons (mitral and tufted, MT cells)....
