Olfactory system

The olfactory system is the sensory system that is responsible for the sense of smell (olfaction). It receives, processes and interprets odour information.

    Dalal et al. provide a thorough review of bilateral hemispheric interactions in the context of odor perception and memory. They summarize reports on anatomy, physiology and behavior related to olfaction. This review provides insights on how odor information can be processed unilaterally and/or bilaterally despite the lack of topographical organization.

    Olfaction is a key sensory modality with high diversity and olfactory defects has been associated with metabolic and neurodegenerative disorders. Here, the authors discovered that specific olfactory inputs actively regulate lipid metabolism in a dynamic and reversible manner.

    Integrating knowledge about the circuit-level organization of the brain into neuromorphic artificial systems is a challenging research problem. The authors present a neural algorithm for the learning of odourant signals and their robust identification under noise, based on the architecture of the mammalian olfactory bulb and implemented on the Intel Loihi neuromorphic system.

    A neurogenetic model, Drosophila sechellia—a relative of Drosophila melanogaster that has developed an extreme specialization for a single host plant—sheds light on the evolution of interspecific differences in behaviour.

    Because of stochastic connections between some brain regions, an identified neuron can receive different inputs across individual animals and yet respond similarly to sensory stimuli. Here the authors reveal the network mechanisms that enable stereotypic sensory responses across individuals.
