Neural stem cells (NSCs) in the adult mouse brain contribute to lifelong brain plasticity. NSCs in the adult ventricular-subventricular zone (V-SVZ) are heterogeneous and, depending on their location in the niche, give rise to different subtypes of olfactory bulb interneurons. Here, we show that during pregnancy multiple regionally-distinct NSCs are dynamically recruited at different times. Coordinated temporal activation of these NSC pools generates sequential waves of short-lived olfactory bulb interneuron subtypes that mature in the mother around birth and in the perinatal care period. Concomitant with neuronal addition, oligodendrocyte progenitors also transiently increase in the olfactory bulb. Thus, life experiences, such as pregnancy, can trigger transient neurogenesis and gliogenesis under tight spatial and temporal control, and may provide a novel substrate for brain plasticity in anticipation of temporary physiological demand.

Stimulation Of

A single, short-duration electrical stimulus delivered to one olfactory bulb evokes a potential in the contralateral bulb. As recorded with a unipolar electrode, the potential is negative central to, and positive peripheral to the external plexiform layer. Bipolar recordings from multiple sites show that the potential is not actively propagated. The potential summates in response to tetanic stimulation and is blocked by anoxia and dimethyl ether d-tubocurarine. In addition to confirming the existence of an interolfactory bulb system, the electrophysiological evidence in conjunction with known anatomical relationships strongly suggests that the evoked potential is a postsynaptic potential of the internal granular cells.

Odorants, inhaled through the nose or exhaled from the mouth through the nose, bind to receptors on olfactory sensory neurons. Olfactory sensory neurons project in a highly stereotyped fashion into the forebrain to a structure called the olfactory bulb, where odorant-specific spatial patterns of neural activity are evoked. These patterns appear to reflect the molecular features of the inhaled stimulus. The olfactory bulb, in turn, projects to the olfactory cortex, which is composed of multiple sub-units including the anterior olfactory nucleus, the olfactory tubercle, the cortical nucleus of the amygdala, the anterior and posterior piriform cortex, and the lateral entorhinal cortex. Due to differences in olfactory bulb inputs, local circuitry and other factors, each of these cortical sub-regions appears to contribute to different aspects of the overall odor percept. For example, there appears to be some spatial organization of olfactory bulb inputs to the cortical nucleus of the amygdala, and this region may be involved in the expression of innate odor hedonic preferences. In contrast, the olfactory bulb projection to the piriform cortex is highly distributed and not spatially organized, allowing the piriform to function as a combinatorial, associative array, producing the emergence of experience-dependent odor-objects (e.g., strawberry) from the molecular features extracted in the periphery. Thus, the full perceptual experience of an odor requires involvement of a large, highly dynamic cortical network.
