Odor perception and olfactory bulb plasticity in adult mammals.
The adult mammalian olfactory bulb (OB) is unique in that olfactory sensory neurons project directly, without prior thalamic relay, to the OB. This review discusses evidence for the direct involvement of the OB in odor perception and its modulation by olfactory experience. We first discuss recent data showing that the OB exhibits a high level of plasticity in response to olfactory experience in...
متن کاملOdor representations in the mammalian olfactory bulb.
A first key step in studying a sensory modality is to define how the brain represents the features of the sensory stimulus. This has proven to be a challenge in olfaction, where even the stimulus features have been a matter of considerable debate. In this review, we focus on olfactory representations in the first stage of the olfactory pathway, the olfactory bulb (OB). We examine the diverging ...
متن کاملOlfactory Bulb: Odor Signals Put into Context
In this issue, Doucette and colleagues demonstrate that information related to whether an odor is currently linked to reward can be observed uniquely in population activity in the olfactory bulb, changing our understanding both of what is coded by the first olfactory relay in the CNS and of how this coding is instantiated.
متن کاملAssessment and discrimination of odor stimuli in rat olfactory bulb by dynamic functional MRI.
Dynamic blood oxygenation level-dependent functional MRI was applied at 7 T in the rat olfactory bulb (OB) with pulsed delivery of iso-amyl acetate (IAA) and limonene. Acquisition times for single-slice and whole OB data were 8 and 32 s, respectively, with spatial resolution of 220 x 220 x 250 micrometer. On an intrasubject basis, short IAA exposures of 0.6 min separated by 3.5-min intervals in...
متن کاملMitral cell temporal response patterns evoked by odor mixtures in the rat olfactory bulb.
Mammals generally have the ability to extract odor information contained in complex mixtures of molecular components. However, odor mixture processing has been studied electrophysiologically only in insects, crustaceans, and fish. As a first step toward a better understanding of this processing in high vertebrates, we studied the representation of odor mixtures in the rat olfactory bulb, i.e., ...
