    Cadherins regulate nuclear topography and function of developing ocular motor circuitry

    Athene Knüfer, Giovanni Diana ... Sarah Guthrie
    Cadherin-dependent cell adhesion controls the contralateral migration and clustering of ocular motor subpopulations and is required for the development of functional eye movements driven by those neurons.

    Optimal compensation for neuron loss

    David GT Barrett, Sophie Denève, Christian K Machens
    Spiking networks compensate the loss of neurons instantaneously, when restoration of excitatory/inhibitory balance becomes equivalent to restoration of functionality.

    A new motor synergy that serves the needs of oculomotor and eye lid systems while keeping the downtime of vision minimal

    Mohammad Farhan Khazali, Joern K Pomper ... Peter Thier
    Involuntary eye movements that keep images positioned over the center of the retina are synchronized with blinks to minimize disruption to vision.

    Sub-cone visual resolution by active, adaptive sampling in the human foveola

    Jenny L Witten, Veronika Lukyanova, Wolf M Harmening
    High-resolution foveal imaging and micro-psychophysics reveal that the human oculomotor system finely adjusts drift motion of the eye in an acuity task to enhance retinal sampling, achieving sub-cell resolution.

    Systemic pharmacological suppression of neural activity reverses learning impairment in a mouse model of Fragile X syndrome

    Amin MD Shakhawat, Jacqueline G Foltz ... Jennifer L Raymond
    The capacity for new cerebellum-dependent learning is influenced by the recent history of neural activity in a mouse model of Fragile X syndrome, suggesting a role for metaplasticity.

    Magnetic eye tracking in mice

    Hannah L Payne, Jennifer L Raymond
    An accurate, robust, and lightweight technique for measuring eye movements in mice was developed using magnetic sensing, yielding the first high resolution recordings of eye movements in freely moving mice.

    Removal of inhibition uncovers latent movement potential during preparation

    Uday K Jagadisan, Neeraj J Gandhi
    Non-invasive disinhibition of the oculomotor system shows that ongoing preparatory activity in the superior colliculus has movement-generating potential and need not rise to threshold in order to produce a saccade.
    1. Neuroscience

    Interactions between circuit architecture and plasticity in a closed-loop cerebellar system

    Hannah L Payne, Jennifer L Raymond, Mark S Goldman
    A comprehensive modeling approach reconciles experimental observations with classic plasticity mechanisms in the cerebellar cortex, demonstrating how learning-related changes in neural activity can appear to contradict the sign of the underlying plasticity when feedback is present.

    Contrast sensitivity reveals an oculomotor strategy for temporally encoding space

    Antonino Casile, Jonathan D Victor, Michele Rucci
    Fixational eye movements transform the spatial scene into temporal modulations on the retina, which, together with the known sensitivities of retinal neurons, provide a comprehensive account of human spatial sensitivity.

    Vestigial auriculomotor activity indicates the direction of auditory attention in humans

    Daniel J Strauss, Farah I Corona-Strauss ... Steven A Hackley
    Recordings of ear muscles in humans show that ears attempt to pivot in the direction that requires attention.
