    Vacillation, indecision and hesitation in moment-by-moment decoding of monkey motor cortex

    Matthew T Kaufman et al.
    Trial-by-trial analysis of neuronal activity in monkeys performing a decision-making task reveals the neural correlates of behaviours including wavering, hesitation and sudden changes of mind.

    Metazoan evolution of glutamate receptors reveals unreported phylogenetic groups and divergent lineage-specific events

    David Ramos-Vicente et al.
    The animal phylogeny of glutamate receptors indicates that vertebrate types do not account for all receptor classes originated during evolution, neither are they the pinnacle of a linear evolutive process.

    Human complex exploration strategies are enriched by noradrenaline-modulated heuristics

    Magda Dubois et al.
    Humans supplement complex, resource-demanding strategies with simple heuristics for solving the exploration-exploitation dilemma, and noradrenaline functioning controls their utilisation.

    Balancing model-based and memory-free action selection under competitive pressure

    Atsushi Kikumoto, Ulrich Mayr
    People compete by trying to outsmart their opponents as long as they win, but show random behavior, and neural signs of suppressing knowledge about opponents’ strategies, when they lose.

    Distinct effects of prefrontal and parietal cortex inactivations on an accumulation of evidence task in the rat

    Jeffrey C Erlich et al.
    Quantitative modeling of inactivations shows the prefrontal cortex (but not parietal cortex) of the rat is obligatory for decisions guided by evidence accumulating longer than 240 ms.

    Tree crickets optimize the acoustics of baffles to exaggerate their mate-attraction signal

    Natasha Mhatre et al.
    Tree crickets can optimize the baffles they make to increase call loudness without any progressive optimization, and manufacture an optimal baffle in a single attempt, by using a simple yet highly accurate heuristic.

    Serial, parallel and hierarchical decision making in primates

    Ariel Zylberberg et al.
    A comparison between hierarchical and flat models of decision-making refutes flat models because they lack flexibility and are not supported by behavioral and neural data.

    Complementary encoding of priors in monkey frontoparietal network supports a dual process of decision-making

    Lalitta Suriya-Arunroj, Alexander Gail
    Probability of upcoming actions modulates subclasses of neurons in frontoparietal motor-planning areas in a complementary fashion and frontal-lobe processing takes the leading role when primates commit to a decision.

    Demographic reconstruction from ancient DNA supports rapid extinction of the great auk

    Jessica E Thomas et al.
    Reconstruction of great auk population dynamics suggests that hunting pressure alone could have been responsible for their extinction, demonstrating that even abundant, widespread species can be vulnerable to intense exploitation.

    Multiple sources of slow activity fluctuations in a bacterial chemosensory network

    Remy Colin et al.
    Single-cell FRET measurements reveal large temporal activity fluctuations within this signaling pathway in Escherichia coli, caused by stochasticity of receptor methylation combined with allosteric interactions and slow rearrangements within receptor clusters.
