    The dorsomedial prefrontal cortex computes task-invariant relative subjective value for self and other

    Matthew Piva et al.
    Activity in the dorsomedial prefrontal cortex encodes relative subjective value in a common neural code across decision-making for self and other and across tasks with divergent cognitive requirements.

    Response repetition biases in human perceptual decisions are explained by activity decay in competitive attractor models

    James J Bonaiuto et al.
    Residual activity from previous trials in a biophysical decision network model causes biases in choice behavior such that a previous response is more likely to be repeated.

    Poor coherence in older people's speech is explained by impaired semantic and executive processes

    Paul Hoffman et al.
    Remaining focused on the topic at hand when speaking depends on effective selection of task-relevant semantic knowledge, and declines in this ability account for increases in off-topic speech in older people.

    The influence of the descending pain modulatory system on infant pain-related brain activity

    Sezgi Goksan et al.
    Greater connectivity of the descending pain modulatory system network in the infant brain is associated with lower pain-related brain activity.

    A connectional hub in the rostral anterior cingulate cortex links areas of emotion and cognitive control

    Wei Tang et al.
    A hub in the rostral anterior cingulate cortex receives unusually high and functionally diverse inputs, providing a biological interface between motivation, incentive based learning, and decision making.

    Primate prefrontal neurons signal economic risk derived from the statistics of recent reward experience

    Fabian Grabenhorst et al.
    Neurons in prefrontal cortex track the variance of experienced rewards to guide economic decisions.

    Human VMPFC encodes early signatures of confidence in perceptual decisions

    Sabina Gherman, Marios G. Philiastides
    Simultaneous EEG-fMRI reveals neural representations of decision confidence unfolding prior to explicit perceptual choices, in a region of the ventromedial prefrontal cortex typically linked to reward processing and value-based decisions.

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

    Jiefeng Jiang et al.
    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

    Model-based fMRI reveals dissimilarity processes underlying base rate neglect

    Sean R O'Bryan et al.
    Model-based imaging shows that the rostrolateral prefrontal cortex supports dissimilarity-based heuristics that people may use when they are confronted with ambiguous scenarios.
