    Superior colliculus drives stimulus-evoked directionally biased saccades and attempted head movements in head-fixed mice

    Sebastian H Zahler, David E Taylor ... Evan H Feinberg
    Mouse gaze shifts are unexpectedly flexible.

    Spatiotemporal interplay between multisensory excitation and recruited inhibition in the lamprey optic tectum

    Andreas A Kardamakis, Juan Pérez-Fernández, Sten Grillner
    Signals conveyed from two different senses from a given point in space converge onto the same neurons of the optic tectum that trigger the gaze-control-system, and at the same time inhibit other parts of the tectal motor map.

    Rapid stimulus-driven modulation of slow ocular position drifts

    Tatiana Malevich, Antimo Buonocore, Ziad M Hafed
    Slow, continuous changes in eye position when gaze is fixed, previously believed to be random drifts, are shown to exhibit highly systematic and short-latency response characteristics to visual stimuli.

    Visual pursuit behavior in mice maintains the pursued prey on the retinal region with least optic flow

    Carl D Holmgren, Paul Stahr ... Jason ND Kerr
    Digital reconstruction of environment combined with eye and head-tracking enabled the process of prey-detection and capture to be seen from the freely moving mouse’s point-of-view and shows the exact visual-field and retinal location mice use when chasing prey and the advantage.

    Monkeys exhibit human-like gaze biases in economic decisions

    Shira M Lupkin, Vincent B McGinty
    A novel animal model of economic decision-making captures complex patterns of choice behavior similar to those of humans, opening the way for mechanistic studies to probe the neural basis for this important form of executive function.

    Foveal vision anticipates defining features of eye movement targets

    Lisa M Kroell, Martin Rolfs
    Before a saccadic eye movement to a location in the visual periphery, human observers' foveal vision becomes more sensitive to the features defining the eye movement target, anticipating information that will soon be fixated in a retinotopic reference frame.

    Disparate substrates for head gaze following and face perception in the monkey superior temporal sulcus

    Karolina Marciniak, Artin Atabaki ... Peter Thier
    A distinct cortical region serves head gaze following, and is needed to establish joint attention with others and to ultimately develop a theory of others' mind.

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

    Vidhyasankar Krishnamoorthy, Michael Weick, Tim Gollisch
    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.
    1. Neuroscience

    Active sensing in the categorization of visual patterns

    Scott Cheng-Hsin Yang, Máté Lengyel, Daniel M Wolpert
    Humans use a near-optimal eye movement strategy to efficiently extract information about high-level visual categories.
    1. Neuroscience

    Cortical network architecture for context processing in primate brain

    Zenas C Chao, Yasuo Nagasaka, Naotaka Fujii
    Large-scale electrocorticography and big data analysis of brain-wide neuronal interactions reveal the architecture of network information flow for context processing in primate brain.
