    Detecting changes in dynamic and complex acoustic environments

    Yves Boubenec et al.
    Psychophysics experiments and EEG recordings reveal that people's performance in detecting unexpected changes in complex auditory scenes can be modeled as a process of sensory evidence accumulation.

    Efficient coding of natural scene statistics predicts discrimination thresholds for grayscale textures

    Tiberiu Tesileanu et al.
    An optimization principle allows natural-image data to predict human sensitivity to synthetic, un-natural textures with multiple gray levels.
    1. Neuroscience

    Across-species differences in pitch perception are consistent with differences in cochlear filtering

    Kerry MM Walker et al.
    Humans and other animals have different strategies for extracting the pitch of sounds, potentially driven by the species-specific frequency selectivity of the ear.

    Post-decision biases reveal a self-consistency principle in perceptual inference

    Long Luu, Alan A Stocker
    Humans are biased in their assessment of sensory information by their own preceding categorical judgment in an attempt to remain self-consistent.
    1. Neuroscience

    Voluntary and involuntary contributions to perceptually guided saccadic choices resolved with millisecond precision

    Emilio Salinas et al.
    Looking away from a salient visual stimulus pits the reflexive urge to look toward it against the voluntary intention not to, and this conflict is resolved within tens of milliseconds.
    1. Neuroscience

    Mouse color and wavelength-specific luminance contrast sensitivity are non-uniform across visual space

    Daniel J Denman et al.
    Mice can detect changes in hue independent of luminance, with differing sensitivity to hue and luminance in different parts of visual space.
    1. Neuroscience

    A circuit mechanism for decision-making biases and NMDA receptor hypofunction

    Sean Edward Cavanagh et al.
    Ketamine, an NMDA receptor antagonist and experimental model for schizophrenia, produces decision-making deficits in monkeys, which are predicted by a lowering of cortical excitation-inhibition balance in a spiking circuit model.

    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.
    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.

    Perceptually relevant remapping of human somatotopy in 24 hours

    James Kolasinski et al.
    A combination of 7 tesla fMRI and psychophysics revealed the reorganisation of the human somatosensory cortex and changes in tactile perceptual abilities after just 24 hours of altered hand use.
