Some forms of olfactory learning require intact noradrenergic terminals in the olfactory bulb that originate from the locus coeruleus. To clarify the action of noradrenergic inputs on the dendrodendritic interaction between mitral and granule cells in the rat olfactory bulb, we analyzed field potent...
