    Distinct neural contributions to metacognition for detecting, but not discriminating visual stimuli

    Matan Mazor et al.
    Combining psychophysics and functional MRI reveals a qualitative asymmetry in neural engagement when reflecting on whether a stimulus is seen (detection) compared to reflecting on what a stimulus is (discrimination).

    Reinforcement biases subsequent perceptual decisions when confidence is low, a widespread behavioral phenomenon

    Armin Lak et al.
    Confidence-dependent reinforcement learning is active and produces trial-to-trial choice updating even in well-learned perceptual decisions without explicit reward biases, across species and sensory modalities.

    Coincidence detection and bi-directional transmembrane signaling control a bacterial second messenger receptor

    Richard B Cooley et al.
    Building on previous work (Chatterjee et al., 2014), the mechanism of coincidence detection in bacterial second messenger signaling across membranes is revealed at a molecular level, providing insight into the regulation of a conserved transmembrane receptor.

    Distinct temporal difference error signals in dopamine axons in three regions of the striatum in a decision-making task

    Iku Tsutsui-Kimura et al.
    Dopamine signals in the ventral, dorsomedial, and dorsolateral striatum are modulated by various variables, such as stimulus-associated value, choice, confidence, but these modulations can be inclusively explained by TD errors.

    Focal optogenetic suppression in macaque area MT biases direction discrimination and decision confidence, but only transiently

    Christopher R Fetsch et al.
    Perceptual decision making in monkeys can be manipulated by using optogenetics to inactivate functional subregions of visual cortex, but the brain has a capacity to compensate for this perturbation.
    1. Neuroscience

    Human observers have optimal introspective access to perceptual processes even for visually masked stimuli

    Megan A K Peters, Hakwan Lau
    Despite the widely held belief among researchers in consciousness that healthy observers can show unconscious perception, a study using a novel method to control for response biases finds no evidence for this phenomenon.
    1. Plant Biology

    Flowering time and seed dormancy control use external coincidence to generate life history strategy

    Vicki Springthorpe, Steven Penfield
    Models of plant behaviour show that flowering early in a warming world is an adaptive strategy to insulate progeny seed behaviour from the affects of climate change.

    Value signals guide abstraction during learning

    Aurelio Cortese et al.
    Valuation of sensory information in the ventromedial prefrontal cortex plays a key function in constructing the abstract representations that guide complex behaviours.
    1. Neuroscience

    Neural evidence accumulation persists after choice to inform metacognitive judgments

    Peter R Murphy et al.
    Error detection is contingent on the continuation of evidence accumulation after choice commitment, and the speed and accuracy of this process are modulated by high-level signals from medial frontal cortex.

    Functional genomics of lipid metabolism in the oleaginous yeast Rhodosporidium toruloides

    Samuel T Coradetti et al.
    Using barcoded mutagenesis and a high-throughput genetic screen results in the identification of 150 genes that affect lipid accumulation in a non-model yeast system.
