    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.

    Task-dependent recurrent dynamics in visual cortex

    Satohiro Tajima et al.
    A decoding-based, state-space reconstruction reveals that neurons in macaque IT cortex change the structure of their collective attractor dynamics depending on task contexts.

    A consensus guide to capturing the ability to inhibit actions and impulsive behaviors in the stop-signal task

    Frederick Verbruggen et al.
    Clear guidelines and open-source software resources are provided for the stop-signal task, in order to streamline the use of this important tool, and to thereby increase its validity and reliability.

    Task-induced functional brain connectivity mediates the relationship between striatal D2/3 receptors and working memory

    Matthew M Nour et al.
    Striatal dopamine 2/3 receptor (D2/3R) availability is related to working memory-induced functional connectivity changes in the default mode network, and this mediates the relationship between D2/3Rs and task performance.

    Pask integrates hormonal signaling with histone modification via Wdr5 phosphorylation to drive myogenesis

    Chintan K Kikani et al.
    PASK phosphorylates Wdr5 to trigger epigenetic changes at lineage specifying promoters resulting in transcriptional derepression and differentiation of stem or progenitor cells.

    The representational dynamics of task and object processing in humans

    Martin N Hebart et al.
    Task representations emerge rapidly throughout human cortex, with parallel object representations in occipitotemporal cortex that are increasingly dominated by task in higher visual areas.

    Distributed task-specific processing of somatosensory feedback for voluntary motor control

    Mohsen Omrani et al.
    Somatosensory feedback is transmitted to many sensory and motor cortical regions within 25 milliseconds and ongoing behavioural tasks alter the spatiotemporal pattern of this perturbation-related activity, supporting rapid motor responses to attain behavioural goals.

    Rapid task-dependent tuning of the mouse olfactory bulb

    Anzhelika Koldaeva et al.
    Sensory representation in the primary olfactory area is rapidly modulated when mice switch between easy and difficult discrimination tasks, optimising the sensory representation for the task at hand.

    The recovery of standing and locomotion after spinal cord injury does not require task-specific training

    Jonathan Harnie et al.
    Restoring locomotion after complete spinal cord injury does not require locomotor training, only the return of sufficient excitability within neurons of the spinal cord.

    The influence of task outcome on implicit motor learning

    Hyosub E Kim et al.
    During a sensorimotor perturbation, task outcome may serve as a gain on implicit adaptation or provide a distinct error signal for a second, independent implicit learning process.
