    The sifting of visual information in the superior colliculus

    Kyu Hyun Lee, Alvita Tran ... Markus Meister
    The superior colliculus reveals hallmarks of sophisticated visual computation, including selectivity, invariance, and stimulus-specific habituation to behaviorally relevant stimuli.

    'Artiphysiology' reveals V4-like shape tuning in a deep network trained for image classification

    Dean A Pospisil, Anitha Pasupathy, Wyeth Bair
    Single units in a deep convolutional neural network trained for image classification develop shape selectivity that is similar to that found in the primate visual cortex.

    Learning place cells, grid cells and invariances with excitatory and inhibitory plasticity

    Simon Nikolaus Weber, Henning Sprekeler
    A large variety of spatial representations implied in rodent navigation could arise robustly and rapidly from inputs with a weak spatial structure, by an interaction of excitatory and inhibitory synaptic plasticity.

    Population codes enable learning from few examples by shaping inductive bias

    Blake Bordelon, Cengiz Pehlevan
    Neural sensory representations impose an inductive bias over the space of learning tasks, allowing some tasks to be learned by a downstream neuron more sample-efficiently than others.

    Neural correlations enable invariant coding and perception of natural stimuli in weakly electric fish

    Michael G Metzen, Volker Hofmann, Maurice J Chacron
    Neural circuits in weakly electric fish perform a set of computations to allow natural communication signals to be perceived independently of their context.

    Factorized visual representations in the primate visual system and deep neural networks

    Jack W Lindsey, Elias B Issa
    High-level visual cortex and leading neural network models of the visual system retain information about multiple visual scene variables in independent, non-interfering dimensions of their population codes.

    Demixed principal component analysis of neural population data

    Dmitry Kobak, Wieland Brendel ... Christian K Machens
    A new data analysis tool provides a concise way of visualizing neural data that summarizes all the relevant features of the population response in a single figure.
    1. Neuroscience

    Attention operates uniformly throughout the classical receptive field and the surround

    Bram-Ernst Verhoef, John HR Maunsell
    A spatially-tuned normalization model accounts for neuronal responses to attended or unattended stimuli that are presented inside the classical receptive field or the surround, and explains various other observations.

    Emergence of transformation-tolerant representations of visual objects in rat lateral extrastriate cortex

    Sina Tafazoli, Houman Safaai ... Davide Zoccolan
    Neuronal recordings from rat visual cortex reveal an object-processing pathway, along which neuronal representations become increasingly capable of supporting recognition of visual objects in spite of variation in their appearance.
    1. Neuroscience

    Unsupervised changes in core object recognition behavior are predicted by neural plasticity in inferior temporal cortex

    Xiaoxuan Jia, Ha Hong, James J DiCarlo
    Temporal continuity-induced plasticity in individual neurons of inferior temporal cortex builds neural representations that underlie robust core object recognition behavior.
