    Sweet neurons inhibit texture discrimination by signaling TMC-expressing mechanosensitive neurons in Drosophila

    Shun-Fan Wu et al.
    Drosophila use distinct sensory mechanisms to detect and integrate the same tactile and taste information in two decision-making tasks that serve two different purposes.

    The role of piriform associative connections in odor categorization

    Xiaojun Bao et al.
    Pharmacological fMRI reveals that associative connections contribute to odor categorization by supporting discrimination and generalization at different stages of the human olfactory system.
    1. Neuroscience

    S-cone photoreceptors in the primate retina are functionally distinct from L and M cones

    Jacob Baudin et al.
    Heterogeneity in perceptual sensitivity of human cone-mediated vision across wavelength originates in the cone photoreceptors, where S cones exhibit distinct functional properties in comparison to L and M cones.
    1. Neuroscience

    Efficient recognition of facial expressions does not require motor simulation

    Gilles Vannuscorps et al.
    It is possible to account for efficient facial expression recognition without having to invoke a mechanism of motor simulation, even in very sensitive and challenging tasks.

    Perceptual processing in the ventral visual stream requires area TE but not rhinal cortex

    Mark AG Eldridge et al.
    Bilateral removal of cortical area 'TE' produced deficits in monkeys' ability to discriminate among images with many similar features, whereas removal of subjacent rhinal cortex did not.

    Conserved visual capacity of rats under red light

    Nader Nikbakht, Mathew E Diamond
    Psychometric measures reveal that, contrary to common assumption, rats have good visual form discrimination capacity under red and even far-red illumination.

    Perturbation of amygdala-cortical projections reduces ensemble coherence of palatability coding in gustatory cortex

    Jian-You Lin et al.
    Blocking input from basolateral amygdala to gustatory cortex (GC) severely reduces the coherence of GC ensemble activity, which negatively affects epochal dynamics involved in driving palatability-driven consumption.

    Optogenetic control shows that kinetic proofreading regulates the activity of the T cell receptor

    O Sascha Yousefi et al.
    Controlling the duration of ligand binding to the T cell receptor by light shows that T cells discriminate stimulatory from non-stimulatory ligands by measuring the dynamics of ligand binding.
    1. Neuroscience

    Functional clustering of dendritic activity during decision-making

    Aaron Kerlin et al.
    In motor cortex pyramidal neurons, diverse task-related signals are distributed throughout the dendritic arbor and compartmentalized by dendritic distance and branching.
    1. Physics of Living Systems

    A mechanism for hunchback promoters to readout morphogenetic positional information in less than a minute

    Jonathan Desponds et al.
    Maternal positional information in the fly embryo can be read rapidly in spite of the gene-expression bottleneck and general examples of regulatory architectures that combine speed and accuracy are provided.
