    Separable gain control of ongoing and evoked activity in the visual cortex by serotonergic input

    Zohre Azimi et al.
    Serotonergic input to visual cortex controls ongoing and evoked activity in a separable manner via distinct receptor pathways.

    A projection specific logic to sampling visual inputs in mouse superior colliculus

    Katja Reinhard et al.
    Transsynaptic viral tracing reveals that neurons in the superior colliculus employ projection specific rules to the sampling of retinal inputs, directing distinct visual features to different downstream targets.

    Effects of visual inputs on neural dynamics for coding of location and running speed in medial entorhinal cortex

    Holger Dannenberg et al.
    Spatial accuracy of grid cell firing correlates with the slope of the local field potential theta frequency vs. running speed relationship and integrates velocity signals over past time.

    Perineuronal nets control visual input via thalamic recruitment of cortical PV interneurons

    Giulia Faini et al.
    Accumulation of perineuronal nets around parvalbumin (PV)-positive inhibitory interneurons closes visual cortical plasticity by selectively down-regulating thalamic synapses onto PV cells in a sensory-dependent manner.

    Selectivity to approaching motion in retinal inputs to the dorsal visual pathway

    Todd R Appleby, Michael B Manookin
    Cells in the primate retina show unexpected sensitivity to approaching motion and optical flow.

    Nonlinear circuits for naturalistic visual motion estimation

    James E Fitzgerald, Damon A Clark
    New computational models provide insights into how the insect brain estimates the speed and direction of movement.

    Representation of visual landmarks in retrosplenial cortex

    Lukas F Fischer et al.
    Retrosplenial cortex encodes landmarks by integrating visual inputs with other task-related variables in a supralinear fashion.
    1. Neuroscience

    Clusters of synaptic inputs on dendrites of layer 5 pyramidal cells in mouse visual cortex

    Onur Gökçe et al.
    A combination of optogenetics and 2-photon calcium imaging reveals spatial prerequisites for non-linear synaptic summation within a defined cortical connection.
    1. Neuroscience

    Biophysics of object segmentation in a collision-detecting neuron

    Richard Burkett Dewell, Fabrizio Gabbiani
    Active dendritic processing enables an individual neuron to discriminate the spatial pattern of synaptic inputs, increasing neural and behavioral selectivity for escaping an impending threat.
    1. Neuroscience

    Human intracranial recordings link suppressed transients rather than 'filling-in' to perceptual continuity across blinks

    Tal Golan et al.
    The brain ensures that blinks do not disrupt vision by deleting signals that represent discontinuities in visual input, rather than by recreating the missing input.
