    Odor identity coding by distributed ensembles of neurons in the mouse olfactory cortex

    Benjamin Roland et al.
    In vivo calcium imaging reveals how odor identity is encoded in the activity of large, distributed ensembles of olfactory cortex neurons in mice.

    Decoding odor quality and intensity in the Drosophila brain

    Antonia Strutz et al.
    The lateral horn can be classified into three functional odor response domains that decode opposing hedonic valences and odor intensity.

    Learning improves decoding of odor identity with phase-referenced oscillations in the olfactory bulb

    Justin Losacco et al.
    Tetrode recordings show that the amplitude of gamma oscillations encodes for information on contextual odorant identity when observed at the peak phase of the theta oscillation in the olfactory bulb.

    The contribution of temporal coding to odor coding and odor perception in humans

    Ofer Perl et al.
    Human participants fail to discriminate between odor sequences that activate the same neurons at different orders, pointing against a substantial role for neuron activation time in the odor code.

    Antagonism in olfactory receptor neurons and its implications for the perception of odor mixtures

    Gautam Reddy et al.
    Computational and theoretical analyses offer novel and unexpected insight into how complex, naturally occurring odor mixtures are parsed and normalized at the very first stage of olfaction.

    Front-end Weber-Fechner gain control enhances the fidelity of combinatorial odor coding

    Nirag Kadakia, Thierry Emonet
    In multi-channel sensory systems, gain adaptation can help maintain not only coding capacity across changes in signal intensity, but also combinatorial representations of odor identity.

    Expanding the olfactory code by in silico decoding of odor-receptor chemical space

    Sean Michael Boyle et al.
    A computational method that can screen thousands of chemicals and predict which odorants will interact with specific odorant receptors in flies may ultimately aid the development of more effective insect repellents.
    1. Neuroscience

    Complementary codes for odor identity and intensity in olfactory cortex

    Kevin A Bolding, Kevin M Franks
    Different features of an odor can be represented in mouse olfactory cortex using the particular ensemble of responsive neurons to represent odor identity and the synchrony of the ensemble activity to represent odor intensity.

    Circuit mechanisms encoding odors and driving aging-associated behavioral declines in Caenorhabditis elegans

    Sarah G Leinwand et al.
    Neurotransmission pathways from primary to secondary neurons encode odor and underlie age-related sensory behavioral declines.
    1. Neuroscience

    Recurrent circuitry is required to stabilize piriform cortex odor representations across brain states

    Kevin A Bolding et al.
    Intracortical circuits in mouse olfactory cortex stabilize odor-evoked activity patterns when upstream inputs, from olfactory bulb, become degraded under anesthesia.
