    Are single-peaked tuning curves tuned for speed rather than accuracy?

    Movitz Lenninger, Mikael Skoglund ... Arvind Kumar
    Single-peaked tuning curves found in early sensory areas are more optimized for quick decoding than accuracy, while multi-peaked tuning curves (e.g. grid cells) give higher accuracy but only at longer time scales.

    Social aversive generalization learning sharpens the tuning of visuocortical neurons to facial identity cues

    Yannik Stegmann, Lea Ahrens ... Matthias J Wieser
    Measures of visuocortical activity during aversive generalization learning revealed sharpened representations of facial identity, reflecting inhibitory interactions between neuronal populations that represent facial features associated with threat versus safety.

    Curvature-processing domains in primate V4

    Rendong Tang, Qianling Song ... Haidong D Lu
    Curvature-preferring neurons in monkey V4 cluster into 0.5-mm patches, which highlights the importance of curvature detection in visual object recognition and the key functional role of V4 in this process.

    Clustered functional domains for curves and corners in cortical area V4

    Rundong Jiang, Ian Max Andolina ... Shiming Tang
    Curves and corners are separately encoded by neurons clustered into functional domains in macaque V4.

    Contrary neuronal recalibration in different multisensory cortical areas

    Fu Zeng, Adam Zaidel, Aihua Chen
    Single-unit recordings from cortical neurons in behaving macaque monkeys expose differential aspects of multisensory plasticity across different multisensory areas during visual–vestibular recalibration.

    Asymmetric retinal direction tuning predicts optokinetic eye movements across stimulus conditions

    Scott C Harris, Felice A Dunn
    Retinal physiology and anatomy and visual behavior reveal how sensory circuits in the retina can shape an organism’s eye movements over a range of ethologically relevant stimulus conditions.

    Unique-region phosphorylation targets LynA for rapid degradation, tuning its expression and signaling in myeloid cells

    Ben F Brian IV, Adrienne S Jolicoeur ... Tanya S Freedman
    The ubiquitin ligase c-Cbl preferentially targets unique-region phosphorylated LynA for rapid degradation, regulating its expression and differentially tuning signaling responsiveness in macrophages and mast cells.

    Parallel processing, hierarchical transformations, and sensorimotor associations along the ‘where’ pathway

    Raymond Doudlah, Ting-Yu Chang ... Ari Rosenberg
    Hierarchical transformations of visual representations, saccade-related activity, and sensorimotor associations occur in parallel at the juncture of visual and parietal cortex.

    Specialized contributions of mid-tier stages of dorsal and ventral pathways to stereoscopic processing in macaque

    Toshihide W Yoshioka, Takahiro Doi ... Ichiro Fujita
    Visual area MT signals binocular disparity quickly and robustly, whereas area V4 or its upstream area transforms the nature of the signals to derive a more sophisticated depth representation.

    Feedback optimizes neural coding and perception of natural stimuli

    Chengjie G Huang, Michael G Metzen, Maurice J Chacron
    Neurophysiological and behavioral approaches reveal how coordinated input from descending pathways shapes the tuning properties of electrosensory neurons in order to optimize coding of natural stimuli through temporal whitening.
