    Perceptually relevant remapping of human somatotopy in 24 hours

    James Kolasinski, Tamar R Makin ... Heidi Johansen-Berg
    A combination of 7 tesla fMRI and psychophysics revealed the reorganisation of the human somatosensory cortex and changes in tactile perceptual abilities after just 24 hours of altered hand use.

    Finger somatotopy is preserved after tetraplegia but deteriorates over time

    Sanne Kikkert, Dario Pfyffer ... Nicole Wenderoth
    Hand somatotopy can be preserved in the primary somatosensory cortex of tetraplegic patients, despite the absence of sensorimotor function and periphery-brain communication, but deteriorates over years after injury.

    A human subcortical network underlying social avoidance revealed by risky economic choices

    Johannes Schultz, Tom Willems ... Rene Hurlemann
    The subjective value of engaging in human social situations, and amygdala and nucleus accumbens activation and their connectivity during social decision-making, vary with social anxiety traits.

    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.

    Stimulus vignetting and orientation selectivity in human visual cortex

    Zvi N Roth, David J Heeger, Elisha P Merriam
    Functional MRI measurements of orientation reflect coarse-scale biases that are wholly determined by second-order interactions between the stimulus aperture and the underlying orientation.
    1. Neuroscience

    Distinct neural mechanisms underlie subjective and objective recollection and guide memory-based decision making

    Yana Fandakova, Elliott G Johnson, Simona Ghetti
    Neural substrates of objective vs. subjective memory states can be distinguished, including their role in supporting decisions aimed at optimizing performance.

    Against cortical reorganisation

    Tamar R Makin, John W Krakauer
    A critical re-evaluation of some of the quintessential examples given as evidence for cortical reorganisation argues that, contrary to the prevalent view, any opportunities for functional change in cortical organisation are incremental and constrained by the underlying structural ‘blueprint'.

    Flexing the principal gradient of the cerebral cortex to suit changing semantic task demands

    Zhiyao Gao, Li Zheng ... Elizabeth Jefferies
    Gradient decomposition of informational connectivity reveals that the principal gradient with the separation of default mode network from sensory-motor systems represents a hallmark of the retrieval of strong conceptual links.

    Dopamine neuron ensembles signal the content of sensory prediction errors

    Thomas A Stalnaker, James D Howard ... Geoffrey Schoenbaum
    Dopamine neurons function as an ensemble to signal a multidimensional feature prediction error.

    Intracranial human recordings reveal association between neural activity and perceived intensity for the pain of others in the insula

    Efe Soyman, Rune Bruls ... Valeria Gazzola
    Intracranial recordings indicate that the insula encodes, in a partially intermixed layout, both static and dynamic cues from different body parts that reflect the intensity of pain experienced by others.
