    Optimal multisensory decision-making in a reaction-time task

    Jan Drugowitsch, Gregory C DeAngelis ... Alexandre Pouget
    Through a combination of modeling and experiments it is shown that humans can near-optimally accumulate decision-related evidence across time and cues even when reaction time is under their control.

    Anxiety dissociates the adaptive functions of sensory and motor response enhancements to social threats

    Marwa El Zein, Valentin Wyart, Julie Grèzes
    Social threats trigger enhanced neural representations within 200 milliseconds in sensory and motor systems of the human brain as a function of anxiety, highlighting its adaptive function in reacting rapidly to dangers in the environment.

    Capturing the temporal evolution of choice across prefrontal cortex

    Laurence T Hunt, Timothy EJ Behrens ... Steven W Kennerley
    Experiments in macaques and humans reveal time-varying changes in prefrontal cortex activity that occur during decisions based on costs and benefits.
    1. Neuroscience

    Testing sensory evidence against mnemonic templates

    Nicholas E Myers, Gustavo Rohenkohl ... Mark G Stokes
    Visual search templates are reactivated only temporarily to act as input filters for target detection.
    1. Neuroscience

    Distinct neural mechanisms underlie the success, precision, and vividness of episodic memory

    Franziska R Richter, Rose A Cooper ... Jon S Simons
    Combining fMRI with continuous model-based measures of retrieval enables the behavioral and neural dissociation of multiple components of episodic memory.
    1. Neuroscience

    Increasing suppression of saccade-related transients along the human visual hierarchy

    Tal Golan, Ido Davidesco ... Rafael Malach
    Similar to spontaneous eye blinks perceptual stability, despite small saccades, is related to actively silencing transients in the high-level ends of both ventral and dorsal visual cortices, while activity in low-level visual cortex remains unstable.
    1. Neuroscience

    Associability-modulated loss learning is increased in posttraumatic stress disorder

    Vanessa M Brown, Lusha Zhu ... Pearl H Chiu
    Veterans with PTSD show increased attention to a history of unexpected outcomes during loss learning, both as measured by computational model-derived behavioral parameters and in increased neural signaling in amygdala and insula.
    1. Neuroscience

    Integrated externally and internally generated task predictions jointly guide cognitive control in prefrontal cortex

    Jiefeng Jiang, Anthony D Wagner, Tobias Egner
    The dorsolateral prefrontal cortex integrates concurrent externally and internally generated predictions of task demand to guide information processing, while the medial prefrontal cortex corrects its prediction error based on actual task demand.
    1. Neuroscience

    Promoting subjective preferences in simple economic choices during nap

    Sizhi Ai, Yunlu Yin ... Jie Shi
    Neurocognitive processing during sleep selectively biases subjective preferences in simple economic choices when the sleeper is stimulated by covert, reward-associated cues.
    1. Neuroscience

    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.
