    Evidence accumulation, not ‘self-control’, explains dorsolateral prefrontal activation during normative choice

    Cendri A Hutcherson, Anita Tusche
    A computational model of decision making suggests that the dorsolateral prefrontal cortex's role in self-control is more associated with evidence accumulation processes than with inhibition or modulation of value.

    Linking the evolution of two prefrontal brain regions to social and foraging challenges in primates

    Sebastien Bouret, Emmanuel Paradis ... Cecile Garcia
    Across primates, volumes of specific brain regions relate to specific socio-ecological factors, bridging the gap between neuro-cognitive operations from laboratory studies and challenges primates face in their natural environment.

    Frontal beta-theta network during REM sleep

    Sujith Vijayan, Kyle Q Lepage ... Sydney S Cash
    Two regions of the frontal lobe – the anterior cingulate cortex and, unexpectedly, the dorsolateral prefrontal cortex – show coordinated rhythmic activity during REM sleep.

    Medial anterior prefrontal cortex stimulation downregulates implicit reactions to threats and prevents the return of fear

    Eugenio Manassero, Giulia Concina ... Benedetto Sacchetti
    Implicit defensive reactions to a learned threat-predictive cue and novel stimuli may be significantly downregulated through a repetitive transcranial magnetic stimulation procedure over the medial anterior prefrontal cortex in humans.

    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.

    Stimulating the hippocampal posterior-medial network enhances task-dependent connectivity and memory

    Kristen N Warren, Molly S Hermiller ... Joel L Voss
    Noninvasive stimulation of hippocampal networks increases connectivity in a functionally-specific manner that is highly relevant to effective episodic memory performance that depends on the targeted network.
    1. Neuroscience

    Neural interactions in the human frontal cortex dissociate reward and punishment learning

    Etienne Combrisson, Ruggero Basanisi ... Andrea Brovelli
    Reward and punishment learning is represented in partly overlapping regions of the brain while relying on specific intra- and inter-regional interactions.

    The effect of perinatal brain injury on dopaminergic function and hippocampal volume in adult life

    Sean Froudist-Walsh, Michael AP Bloomfield ... Oliver Howes
    Perinatal brain injury is associated with altered dopaminergic function and reduced hippocampal volume in adulthood in humans.
    1. Neuroscience

    Dorsolateral prefrontal activity supports a cognitive space organization of cognitive control

    Guochun Yang, Haiyan Wu ... Jiefeng Jiang
    The dorsolateral prefrontal cortex represents different conflict types within an organized cognitive space of cognitive control, positioning more similar conflict types closer together.
    1. Neuroscience

    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.
