    Probing the decision-making mechanisms underlying choice between drug and nondrug rewards in rats

    Youna Vandaele, Magalie Lenoir ... Serge H Ahmed
    In a drug choice setting, rats’ preference is initially driven by deliberative processes but shifts to more automatic selection processes after extended training, in accordance with the sequential choice model.

    Monkeys exhibit human-like gaze biases in economic decisions

    Shira M Lupkin, Vincent B McGinty
    A novel animal model of economic decision-making captures complex patterns of choice behavior similar to those of humans, opening the way for mechanistic studies to probe the neural basis for this important form of executive function.

    Choice history biases subsequent evidence accumulation

    Anne E Urai, Jan Willem de Gee ... Tobias H Donner
    Choice history signals bias the interpretation of current sensory input, akin to shifting endogenous attention toward (or away from) the previously selected interpretation.

    Automated annotation of birdsong with a neural network that segments spectrograms

    Yarden Cohen, David Aaron Nicholson ... Timothy J Gardner
    A machine learning model, TweetyNet, make it possible to scale up annotation of birdsong across individual birds, days of song, and species.

    Flexible theta sequence compression mediated via phase precessing interneurons

    Angus Chadwick, Mark CW van Rossum, Matthew F Nolan
    A new model for phase precession accounts for theta sequence generation, suggests critical roles for interneurons, and predicts circuit properties to optimise memory storage.

    Resource-rational account of sequential effects in human prediction

    Arthur Prat-Carrabin, Florent Meyniel, Rava Azeredo da Silveira
    A proposed model of optimal inference under cognitive costs accounts for human sequential effects, including subtle patterns of attractive and repulsive influence of past observations, in a binary prediction task across a wide range of stimulus conditions.
    1. Neuroscience

    Neural evidence accumulation persists after choice to inform metacognitive judgments

    Peter R Murphy, Ian H Robertson ... Redmond G O'Connell
    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.

    Neuronal origins of reduced accuracy and biases in economic choices under sequential offers

    Weikang Shi, Sebastien Ballesta, Camillo Padoa-Schioppa
    Neuronal activity in the primate orbitofrontal cortex reveals different choice biases observed when offers are presented sequentially originate at different stages of the decision process.

    Sequential selection of economic good and action in medial frontal cortex of macaques during value-based decisions

    Xiaomo Chen, Veit Stuphorn
    Whenever monkeys are required to choose between multiple options, neural responses indicate that they first select the desired outcome and then use this information to guide their actions.
    1. Neuroscience

    A common mechanism underlies changes of mind about decisions and confidence

    Ronald van den Berg, Kavitha Anandalingam ... Daniel M Wolpert
    Initial confidence and choice in a decision, and their potential revision, arise from a common mechanism that challenges models that claim confidence and decision processes are dissociated.
