    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.

    An excitatory amacrine cell detects object motion and provides feature-selective input to ganglion cells in the mouse retina

    Tahnbee Kim et al.
    The mouse visual system is able to detect small moving objects due to the activity of VG3-amacrine cells, an unusual type of modulatory cell that uses the transmitter glutamate to activate retinal output cells.

    Sensitivity to image recurrence across eye-movement-like image transitions through local serial inhibition in the retina

    Vidhyasankar Krishnamoorthy et al.
    The encoding of visual images by certain retinal ganglion cells is fundamentally altered in the context of eye-movement-like image transitions; the transitions trigger inhibitory interactions, which make these cells particularly sensitive to recurring images.

    A visual circuit uses complementary mechanisms to support transient and sustained pupil constriction

    William Thomas Keenan et al.
    A single class of neurons switches both its sensory detection and neurotransmission mechanisms to support transient or sustained physiological output.

    Retinal direction selectivity in the absence of asymmetric starburst amacrine cell responses

    Laura Hanson et al.
    Experimental and computational models reveal how parallel 'core' mechanisms shape direction selectivity at the dendrites of starburst amacrine cells and ganglion cells in the mouse retina.

    S-cone photoreceptors in the primate retina are functionally distinct from L and M cones

    Jacob Baudin et al.
    Heterogeneity in perceptual sensitivity of human cone-mediated vision across wavelength originates in the cone photoreceptors, where S cones exhibit distinct functional properties in comparison to L and M cones.

    Protocadherin-dependent dendritic self-avoidance regulates neural connectivity and circuit function

    Dimitar Kostadinov, Joshua R Sanes
    Patterning of dendrites by protocadherin-dependent self-avoidance and self/non-self discrimination is required for proper function of a retinal circuit that computes the direction of motion.

    Inferring synaptic inputs from spikes with a conductance-based neural encoding model

    Kenneth W Latimer et al.
    The conductance-based encoding model creates a new bridge between statistical models and biophysical models of neurons, and infers visually-evoked excitatory and inhibitory synaptic conductances from spike trains in macaque retina.

    Cross-synaptic synchrony and transmission of signal and noise across the mouse retina

    William N Grimes et al.
    Cells within the retina synchronize transmitter release across their output synapses in the dark, reducing the impact of noise generated at these synapses and allowing light-dependent signals to be transmitted with minimal added synaptic noise.

    Local processing in neurites of VGluT3-expressing amacrine cells differentially organizes visual information

    Jen-Chun Hsiang et al.
    Neurite arbors of VGluT3-expressing amacrine cells (VG3-ACs) process visual information locally uniformly detecting object motion while varying in contrast preferences; and in spite of extensive overlap between arbors of neighboring cells population activity in the VG3-AC plexus encodes stimulus positions with subcellular precision.
