    Dynamic modulation of decision biases by brainstem arousal systems

    Jan Willem de Gee, Olympia Colizoli ... Tobias H Donner
    Rapid increases in the brain’s level of alertness, or arousal, contribute to variability in decision making by reducing existing biases.

    Decision and navigation in mouse parietal cortex

    Michael Krumin, Julie J Lee ... Matteo Carandini
    When mice use vision to choose their trajectories, a large fraction of parietal cortex activity can be precisely predicted from navigational attributes such as spatial position and heading.

    Humans strategically shift decision bias by flexibly adjusting sensory evidence accumulation

    Niels A Kloosterman, Jan Willem de Gee ... Johannes Jacobus Fahrenfort
    Decision-makers are able to intentionally control neural excitability to strategically bias sensory evidence accumulation towards the decision bound that maximizes reward within a given ecological context.

    Calcium dynamics regulating the timing of decision-making in C. elegans

    Yuki Tanimoto, Akiko Yamazoe-Umemoto ... Koutarou D Kimura
    A series of quantitative behavioural and opto-physiological analyses using a novel robot microscope system reveals that C. elegans computes the time-differential and time-integral of sensory information for decision-making during olfactory navigation.

    Metacontrol of decision-making strategies in human aging

    Florian Bolenz, Wouter Kool ... Ben Eppinger
    Older adults show reduced adaptation of decision-making strategies to dynamically changing situational demands.

    Patterning precision under non-linear morphogen decay and molecular noise

    Jan Andreas Adelmann, Roman Vetter, Dagmar Iber
    Statistical analysis of morphogen gradients indicates that non-linear morphogen decay does not lead to significantly increased patterning precision, and in fact, the opposite is observed far from the source.

    Monkey plays Pac-Man with compositional strategies and hierarchical decision-making

    Qianli Yang, Zhongqiao Lin ... Tianming Yang
    Macaque monkeys play Pac-Man with strategy-based hierarchical decision-making, a cognitive capacity hitherto unknown in them.

    Flexible control of representational dynamics in a disinhibition-based model of decision-making

    Bo Shen, Kenway Louie, Paul Glimcher
    Local disinhibition provides a biologically plausible mechanism for flexible top-down control of network states that integrates normalized value coding, winner-take-all choice, and persistent activity in a single circuit of decision-making.

    Intraparietal stimulation disrupts negative distractor effects in human multi-alternative decision-making

    Carmen Kohl, Michelle XM Wong ... Bolton KH Chau
    Divisive normalisation effects on decision making caused by distractor options can be reduced by stimulating the parietal cortex using transcranial magnetic stimulation.

    Quantifying decision-making in dynamic, continuously evolving environments

    Maria Ruesseler, Lilian Aline Weber ... Laurence Tudor Hunt
    Human behaviour in a continuous decision making task adapts to the overall statistics of the sensory environment, and these adaptations are also reflected in changes in neural responses to incoming sensory evidence.
