    A resource-rational theory of set size effects in human visual working memory

    Ronald van den Berg, Wei Ji Ma
    Set size effects in visual working memory are explained as a resource-rational trade-off between an error-based behavioral cost and a neural encoding cost.

    A prediction model of working memory across health and psychiatric disease using whole-brain functional connectivity

    Masahiro Yamashita et al.
    Human neuroimaging and machine learning reveals a generalizable relationship between brain connectivity and working memory ability across healthy populations and distinct psychiatric diagnoses.

    Active information maintenance in working memory by a sensory cortex

    Xiaoxing Zhang et al.
    Delay-period activity of anterior piriform cortex is important for working memory tasks requiring active maintenance and encodes the maintained information.
    1. Neuroscience

    Cross-frequency synchronization connects networks of fast and slow oscillations during visual working memory maintenance

    Felix Siebenhühner et al.
    Cross-frequency synchronization of neuronal oscillations in visual and attentional brain systems predicts human working memory performance.
    1. Neuroscience

    A theory of working memory without consciousness or sustained activity

    Darinka Trübutschek et al.
    Visual information can be maintained in non-conscious working memory for several seconds via short-term changes in synaptic weights.

    Canonical goal-selective representations are absent from prefrontal cortex in a spatial working memory task requiring behavioral flexibility

    Claudia Böhm, Albert K Lee
    Representation of goals in the forms previously reported in the PFC is not required for performance of a novel spatial working memory task where goal information must be used flexibly.

    Externally induced frontoparietal synchronization modulates network dynamics and enhances working memory performance

    Ines R Violante et al.
    Externally induced synchronous/desynchronous oscillations during working memory performance reveal distinct patterns of brain activity and connectivity across large-scale networks recruited by the task.

    Dissociated sequential activity and stimulus encoding in the dorsomedial striatum during spatial working memory

    Hessameddin Akhlaghpour et al.
    During a spatial working memory task, neurons in the dorsomedial striatum encode the sample stimulus most strongly towards the onset of the delay period, while they display sequential firing activity that more evenly spans the delay period.

    The expression of established cognitive brain states stabilizes with working memory development

    David Florentino Montez et al.
    The excessive behavioral variability associated with adolescence is the result of greater instability of widespread or global gain signals which produces greater variability in the amplitude of expression of whole-brain states of task-related activity.
    1. Neuroscience

    Minimally dependent activity subspaces for working memory and motor preparation in the lateral prefrontal cortex

    Cheng Tang et al.
    The evidence of subspace computation in the lateral prefrontal cortex provides insights into the neural mechanisms underlying cognitive flexibility and interference between different cognitive processes.
