    Visual objects from similar semantic categories present activity patterns that cluster together in higher visual areas. The authors show that conscious access differs between semantic categories and is driven by category-related visual features commonly associated with processing in higher level visual areas.

    In rodents, cells in the medial entorhinal cortex and subiculum are known to encode the allocentric direction to nearby walls and boundaries. Here, using fMRI the authors show that this is also true in humans, with allocentric boundary direction being encoded in posterior entorhinal cortex and subiculum.

    Practice can improve the perception of stimuli used to achieve a task (perceptual learning). Here, the authors show in monkeys that perceptual learning can be produced even for irrelevant stimuli if the stimuli are paired with stimulation of a dopaminergic centre, the ventral tegmental area (VTA).

    It is known that attention can modify the brain's representations of sensory stimuli to enhance features of importance. Here, the authors show that flexible readout of cortical representations is also required to explain the behavioral effects of attention.

    No effective therapies exist for dry age-related macular degeneration. In this perspective, the authors propose that research should emphasize system biology approaches that integrate various ‘omics’ data into mathematical models to establish pathogenic mechanisms on which to design novel treatments, and identify biomarkers that predict disease progression and therapeutic response.

    It is thought that higher cortical areas are more plastic than lower ones, but there is little direct evidence for this. Here, the authors show that plasticity (defined as lower heritability) of functional connectivity decreases from early to mid-level visual cortex, and then increases further up the visual hierarchy.

    What is the function of color vision? Here, the authors show that when retinal mechanisms of color are impaired, memory has a paradoxical impact on color appearance that is selective for faces, providing evidence that color contributes to face encoding and social communication.

    The visual system excels at segregating moving objects from their backgrounds, a key visual function hypothesized to be driven by suppressive centre-surround mechanisms. Here, the authors show that spatial suppression of background motion signals is critical for rapid segmentation of moving objects.

    The praying mantis, a predatory insect, estimates depth via binocular vision. In this way, the animal decides whether prey is within reach. Here, the authors explore the neural correlates of binocular distance estimation and report that individual neurons are tuned to specific locations in 3D space.

    The mechanisms of contextual modulation in direction selective ganglion cells in the retina remain unclear. Here, the authors find that that On-Off direction-selective ganglion cells are differentially sensitive to discontinuities of dark and bright moving edges in the visual environment and, using synapse-specific genetic manipulations with functional measurements, reveal the microcircuits underlying this contextual sensitivity.

    The perception of spatial patterns (form vision) is thought to rely on rod and cone cells in the retina. Here, the authors show that a third kind of retinal cell, melanopsin-expressing ganglion cells, can also detect form in humans, under particular conditions.

    Ribbon synapses in our sensory nervous system are central to hearing and sight, yet little is known about how these synapses are assembled and maintained during development. In this study, authors use live imaging techniques to monitor ribbon appearance, loss and maintenance in a retinal circuit during development to show that nascent synapses comprising of both ribbons and PSD95 are more stable over time compared to contacts without ribbons.

    We can rapidly determine the gender, age and identity of a face, but the exact steps involved are unclear. Here, the authors show using magnetoencephalography (MEG) that gender and age are encoded in the brain before identity, and reveal the role of familiarity in the earliest stages of face processing.

    Activating the spared neurons downstream of rods and cones is a potential therapeutic approach for retinal degeneration, but has been limited by the characteristics of the opsins available. Here, the authors use medium wavelength cone opsin which has faster kinetics than others and show that it resolves some of these difficulties in a mouse model.

    Neural architecture may be shaped by selection, but is likely also constrained by development. Here, Keesey and colleagues find an inverse relationship between allocation towards visual and olfactory sensory systems across the genus Drosophila, which may reflect a developmental trade-off.

    Sensory systems produce stable stimulus representations despite constant changes across multiple stimulus dimensions. Here, the authors reveal dynamic neural coding mechanisms by testing how coding of one dimension (orientation) changes with adaptations to other dimensions (luminance and contrast).

    The pulvinar is involved in vision and attention, but its interactions with other brain regions are little-studied. Here, using fMRI the authors show that the human pulvinar has widespread functional coupling with cortical areas that reflects its intrinsic organization and the topographic layout of cortex.

    Perceptual learning, the improvement in perceptual abilities with training, is thought to involve changes in neuronal 'tuning'. Here, the authors show that perceptual learning works by making neurons increasingly sensitive to task-relevant differences in stimuli, and by improving population coding mechanisms.

    The neural mechanisms underlying the suppression of fMRI responses to repeated stimuli are under debate. Here, the authors compare computational models to show that only a local scaling model can fit univariate and multivariate fMRI repetition effects across two paradigms and multiple brain regions.

    Adaptation is thought to improve discrimination by pulling neural representations of similar stimuli farther apart. Here, the authors separately show that adaptation to a 3D shape class leads to better discrimination performance on similar shapes, and activity patterns diverge in object selective cortical areas.

    The presence of opposite horizontal motion in the two eyes is a cue for perceiving motion-in-depth, but also leads to suppressed motion sensitivity. Here, the authors address this paradox and show that spatial and interocular integration mechanisms, distinct from the extraction of motion-in-depth, drive suppression.

    Glaucoma is a neurodegenerative disease of which the etiology is still unclear. Here the authors show that elevation of intraocular pressure induces T cell infiltration in the eyes. Furthermore, they show that T cell cross-reactivity between endogenous and commensal antigens contributes to disease onset in mice.

    Attention reduces correlated variability in population activity, however the effect of fluctuations in attentional state has not been studied. Here, the authors report in a novel visual task that fluctuations in attentional allocation have a pronounced effect on correlated variability at longer timescales.

    The precise role of PPC in transforming sensory signals to relevant actions is not yet clear. Here, the authors show that unlike V1, which is largely driven by visual input, PPC is strongly task-dependent and exhibits a mixture of stimulus and choice signals in a visual decision task.

    Thalamo-cortical circuit dynamics are tuned according to behavioral demands, yet the neural mechanisms are not well understood. Here the authors report arousal level-dependent switch in the functional interactions between the thalamus and cortex in ferrets both in spontaneous activity as well as during visual processing.

    Feedback modulation of V1 is implicated in functions such as attention yet the precise neural mechanisms are not known. Here the authors report that optogenetic inactivation of V2 projections leads to modulation of V1 receptive field properties such as size, surround suppression and response amplitude.

    Inferotemporal cortex (IT) neurons respond to specific objects but the precise neural mechanisms for clutter-invariant representation is not known. Here the authors show that face and body patch IT neurons respond to multiple objects with winner-take-all, contralateral-take-all or weighted averaging depending on the stimulus properties.

    Proteasomal overload can be found in a broad spectrum of mouse models of retinal degeneration. Here the authors find that overexpressing the PA28α subunit of the 11S proteasome cap increased the number of surviving functional photoreceptor cells in a mouse model of retinal degeneration bearing the P23H mutation in rhodopsin.

    Population receptive fields (pRFs) in the visual system are key information-processors, but how they develop is unknown. Here, authors use fMRI and pRF modeling in children and adults to show that in the ventral stream only pRFs in face- and word-selective regions continue to develop, mirroring changes in viewing behavior.
