    Gradients in the biophysical properties of neonatal auditory neurons align with synaptic contact position and the intensity coding map of inner hair cells

    Alexander L Markowitz, Radha Kalluri
    The biophysical diversity that is intrinsic to spiral ganglion neurons emerges as spatial gradients during early post-natal development and endures through subsequent maturation to likely contribute to sound intensity coding.

    Sources of noise during accumulation of evidence in unrestrained and voluntarily head-restrained rats

    Benjamin B Scott et al.
    Statistical analysis of evidence-based decisions reveals new insights into the source of behavioral variability.

    Prognostication of chronic disorders of consciousness using brain functional networks and clinical characteristics

    Ming Song et al.
    Behavioral, pharmacological, optogenetic, electrophysiological and computational analyses suggest that the anterior dorsal striatum is a causal node in the network responsible for evidence accumulation.

    A Bayesian model of context-sensitive value attribution

    Francesco Rigoli et al.
    The dependence of incentive value attribution on the anticipation of rewards within a given context is explained via a normative Bayesian account of how rewards map to incentive values.

    Habitat and social factors shape individual decisions and emergent group structure during baboon collective movement

    Ariana Strandburg-Peshkin et al.
    For baboons on the move, habitat features across multiple spatial scales combine with social interactions to impact the movements of individuals, ultimately shaping the structure of the whole group.

    Noncoding RNA-nucleated heterochromatin spreading is intrinsically labile and requires accessory elements for epigenetic stability

    R A Greenstein et al.
    Heterochromatin spreading in fission yeast predominantly produces intergenerationally unstable outcomes, requiring an accessory element that represses histone turnover.

    Natural variation in autumn expression is the major adaptive determinant distinguishing Arabidopsis FLC haplotypes

    Jo Hepworth et al.
    Variation in autumnal expression from starting expression levels and initial cold-down-regulation, rather than epigenetic silencing, is the major field variable conferred by worldwide haplotypes of the floral repressor gene, FLC.

    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.

    The hippocampus supports deliberation during value-based decisions

    Akram Bakkour et al.
    The deliberation involved in simple preference decisions, such as those between two familiar snacks, depends on the hippocampus.

    A stochastic epigenetic switch controls the dynamics of T-cell lineage commitment

    Kenneth KH Ng et al.
    The timing and outcome of mammalian cell lineage decisions can be controlled by slow, stochastic events on individual regulatory gene loci.
