Distinct lateral inhibitory circuits affect spiking in olfactory bulb mitral and tufted cells differently, which ultimately allows each cell type to best discriminate between similar odors in separate concentration ranges.
The essential role of presynaptic NMDA receptors for granule cell GABAergic output elucidates the function of reciprocal spines in recurrent and possibly lateral inhibition of mitral cells during olfactory processsing.
While both implicit and explicit learning augment neurogenesis, adult-born cells differ in their morphology, functional coupling and inhibitory action impacting differentially the olfactory bulb output.
A spiking network model that examines the transformation of odor information from olfactory bulb to piriform cortex demonstrates how intrinsic cortical circuitry preserves representations of odor identity across odorant concentrations.
Adult neural stem cells differ in the types of neurons they generate according to their location and new territories and genes associated with dorsal and ventral neurogenic lineages in the adult mouse brain are revealed.
Male and female mice respond differently to the same pheromone signals, and the representation of these sensory stimuli by neurons in the medial amygdala correlates precisely with the differences in behavior.
