    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.

    Mapping odorant sensitivities reveals a sparse but structured representation of olfactory chemical space by sensory input to the mouse olfactory bulb

    Shawn D Burton, Audrey Brown ... Matt Wachowiak
    Large-scale mapping of sensory input to the mouse olfactory bulb reveals exceptionally narrow tuning of olfactory receptor input to glomeruli and defines a functional map of glomerular sensitivities that is structured with respect to olfactory chemical space.

    Intercollicular commissural connections refine the representation of sound frequency and level in the auditory midbrain

    Llwyd David Orton, Adrian Rees
    Deactivation of one side of the auditory midbrain while recording in the other shows that the two sides cooperate in processing frequency and in enhancing the encoding of sound level.

    Functional links between sensory representations, choice activity, and sensorimotor associations in parietal cortex

    Ting-Yu Chang, Raymond Doudlah ... Ari Rosenberg
    The fidelity of 3D visual object representations, choice-related activity, and experience-dependent sensorimotor associations are functionally linked in the caudal intraparietal area.

    Stability of motor representations after paralysis

    Charles Guan, Tyson Aflalo ... Richard A Andersen
    Neural populations in PPC dynamically represent motor-like and then sensory-like aspects of brain–computer interface finger movements with a representational structure that matches able-bodied individuals.

    Neural dynamics of causal inference in the macaque frontoparietal circuit

    Guangyao Qi, Wen Fang ... Liping Wang
    In causal inference, the premotor cortex dynamically integrates prior information and current sensory inputs to infer hidden structures, and selectively updates sensory representations in the parietal cortex to support behavior.

    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.

    Visual experience has opposing influences on the quality of stimulus representation in adult primary visual cortex

    Brian B Jeon, Thomas Fuchs ... Sandra J Kuhlman
    Stimulus representation in primary visual cortex rebounds to its original state following therapeutic sensory deprivation in adults.
    1. Neuroscience

    Temporal structure in associative retrieval

    Zeb Kurth-Nelson, Gareth Barnes ... Peter Dayan
    Neural representations are fast-evolving trajectories, and distinct components of these trajectories reappear during retrieval with distinct consequences for learning.
    1. Neuroscience

    Empathic pain evoked by sensory and emotional-communicative cues share common and process-specific neural representations

    Feng Zhou, Jialin Li ... Benjamin Becker
    Machine learning analyses reveal that the observation of acute pain inflictions and facial expressions of pain evoke shared pain-specific neural representations.
