    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.

    Consolidation alters motor sequence-specific distributed representations

    Basile Pinsard, Arnaud Boutin ... Julien Doyon
    The consolidation of newly acquired motor skills induces a functional reorganization of sequential information representations within secondary motor cortex, basal ganglia and hippocampus.

    Ultra-Rapid serial visual presentation reveals dynamics of feedforward and feedback processes in the ventral visual pathway

    Yalda Mohsenzadeh, Sheng Qin ... Dimitrios Pantazis
    Reducing visibility with higher image presentation rates increases recurrent processing demands along the visual processing pathway to resolve object recognition.

    Evidence for a deep, distributed and dynamic code for animacy in human ventral anterior temporal cortex

    Timothy T Rogers, Christopher R Cox ... Matthew A Lambon Ralph
    Signals recorded directly from human anterior temporal cortex reveal that the brain represents animacy information using a distributed code that changes radically as a stimulus is processed, as predicted by an artificial neural network model.

    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.

    Multivariate stochastic volatility modeling of neural data

    Tung D Phan, Jessica A Wachter ... Michael J Kahana
    Multivariate stochastic volatility models provide insights into understanding the dynamics and connectivity of neural signals during cognitive tasks.

    Shared and modality-specific brain regions that mediate auditory and visual word comprehension

    Anne Keitel, Joachim Gross, Christoph Kayser
    The comprehension of acoustic and visual speech depends on modality-specific pathways in the brain, which explains why auditory speech abilities and lip reading are not associated in typical adults.

    Comprehensive characterization of tumor microenvironment in colorectal cancer via molecular analysis

    Xiangkun Wu, Hong Yan ... Li Liang
    Integrated molecular analysis demonstrated that colorectal cancer can be classified into four molecular subtypes (proliferative, immunomodulatory, immunosuppressed, and immune-excluded subtypes), providing valuable insight into the intricate relationship between tumor microenvironment heterogeneity and various clinical phenotypes.

    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.
    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.
