    Sparse genetic tracing reveals regionally specific functional organization of mammalian nociceptors

    William Olson et al.
    Single-nociceptor tracing reveals a novel somatotopic organization for the mammalian pain system, and physiological recordings and peripheral optogenetic behavior assays suggest that it is a possible mechanism underlying region-specific pain sensation.

    Object Recognition: Do rats see like we see?

    Nicole C Rust
    Like primates, the rat brain areas thought to be involved in visual object recognition are arranged in a hierarchy.

    Sensory dynamics of visual hallucinations in the normal population

    Joel Pearson et al.
    A new method for inducing, measuring and modelling visual hallucinations in healthy people reveals that hallucinations share common underlying mechanisms with normal sensory perception.

    A hierarchy of timescales explains distinct effects of local inhibition of primary visual cortex and frontal eye fields

    Luca Cocchi et al.
    The selective effect of local inhibition on diffuse patterns of brain connectivity can be accounted for by an intrinsic hierarchical ordering of cortical timescales.

    Neural activity in a hippocampus-like region of the teleost pallium is associated with active sensing and navigation

    Haleh Fotowat et al.
    Sparse firing in a hippocampus-like structure of the teleost telencephalon is linked to spatial navigation and active sensing.

    Surface color and predictability determine contextual modulation of V1 firing and gamma oscillations

    Alina Peter et al.
    Colored surfaces induce strong gamma-synchronization yet sparse firing in V1 when receptive field inputs are predicted from the surrounding spatial context.

    Pre-saccadic remapping relies on dynamics of spatial attention

    Martin Szinte et al.
    To see the world stable across saccades, the brain compensates retinal shifts induced by the movements, pre-saccadic maps of sensitivity reveal that this process takes time and follows attentional dynamics.

    Microsaccadic sampling of moving image information provides Drosophila hyperacute vision

    Mikko Juusola et al.
    New experiments and theory reveal how the ability to see image details depends upon photoreceptor function and eye movements, and how fruit flies (Drosophila) see spatial details beyond the optical limit of their compound eyes.

    Increasing suppression of saccade-related transients along the human visual hierarchy

    Tal Golan et al.
    Similar to spontaneous eye blinks perceptual stability, despite small saccades, is related to actively silencing transients in the high-level ends of both ventral and dorsal visual cortices, while activity in low-level visual cortex remains unstable.

    Optogenetically induced low-frequency correlations impair perception

    Anirvan Nandy et al.
    Low-frequency correlations among neurons in monkey visual area V4 impair the animal's ability to perform an attention-demanding task, suggesting a causal role of these fluctuations in perception.
