    Human premotor areas parse sequences into their spatial and temporal features

    Katja Kornysheva, Jörn Diedrichsen
    Neuroimaging provides novel insights into how the motor system represents sequences of actions by automatically separating their spatial and temporal features for flexible skill production.

    Recruitment of the default mode network during a demanding act of executive control

    Ben M Crittenden, Daniel J Mitchell, John Duncan
    The default mode network in the brain is activated during the performance of executive-type tasks when a substantial change in cognitive contents is required.
    1. Neuroscience

    Mesolimbic confidence signals guide perceptual learning in the absence of external feedback

    Matthias Guggenmos, Gregor Wilbertz ... Philipp Sterzer
    Neural confidence signals can take the role of reward signals and explain perceptual learning without external feedback as a form of internal reinforcement learning.

    The role of piriform associative connections in odor categorization

    Xiaojun Bao, Louise LG Raguet ... Jay A Gottfried
    Pharmacological fMRI reveals that associative connections contribute to odor categorization by supporting discrimination and generalization at different stages of the human olfactory system.
    1. Neuroscience

    Revealing the neural fingerprints of a missing hand

    Sanne Kikkert, James Kolasinski ... Tamar R Makin
    The brain continues to represent individual fingers in primary somatosensory cortex decades after the amputation of a hand, indicating that cortical maps do not require ongoing sensory input from the body.
    1. Neuroscience

    Neural pattern change during encoding of a narrative predicts retrospective duration estimates

    Olga Lositsky, Janice Chen ... Kenneth A Norman
    Judgments of how much time elapsed between two events in a story are predicted by changes in fMRI activity patterns.
    1. Neuroscience

    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.
    1. Neuroscience

    Neuronal populations in the occipital cortex of the blind synchronize to the temporal dynamics of speech

    Markus Johannes Van Ackeren, Francesca M Barbero ... Olivier Collignon
    Blind people re-purpose the brain's visual areas for tracking speech rhythm.
    1. Neuroscience

    Multi-scale mapping along the auditory hierarchy using high-resolution functional UltraSound in the awake ferret

    Célian Bimbard, Charlie Demene ... Yves Boubenec
    Functional UltraSound imaging allows mapping tonotopic organisation in multiple auditory subcortical and cortical brain structures with an unprecedented spatial functional resolution, while giving access to long-distance top-down connectivity pattern from frontal cortex to auditory cortex.
    1. Neuroscience

    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.
