    Eye morphogenesis driven by epithelial flow into the optic cup facilitated by modulation of bone morphogenetic protein

    Stephan Heermann, Lucas Schütz ... Joachim Wittbrodt
    The lens-averted domains of the optic vesicle are reservoirs of neuroretinal cells that flow into the developing optic cup in a process that is critically influenced by BMP signaling.

    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.

    Airflow and optic flow mediate antennal positioning in flying honeybees

    Taruni Roy Khurana, Sanjay P Sane
    Honeybees determine their flight speed by combining feedback from optic flow and airflow.

    Distinct spatial coordinate of visual and vestibular heading signals in macaque FEFsem and MSTd

    Lihua Yang, Yong Gu
    In both frontal and temporal–parietal visual cortices of macaque, distinct spatial coordinates of visual and vestibular signals are predominantly eye centered and head centered, respectively.

    Role of visual and non-visual cues in constructing a rotation-invariant representation of heading in parietal cortex

    Adhira Sunkara, Gregory C DeAngelis, Dora E Angelaki
    Visual information (optic flow) can be used to discount self-generated rotations and aid in the accurate representation of heading.

    Using an achiasmic human visual system to quantify the relationship between the fMRI BOLD signal and neural response

    Pinglei Bao, Christopher J Purington, Bosco S Tjan
    The lower-level retinotopic visual cortex of humans born without the optic chiasm comprises two independent neuronal populations and forms a versatile model for quantifying the relationship between the fMRI BOLD signal and neural response.

    Influence of sensory modality and control dynamics on human path integration

    Akis Stavropoulos, Kaushik J Lakshminarasimhan ... Dora E Angelaki
    Human path integration accuracy is strongly influenced by the underlying control dynamics, but less so when visual, rather than vestibular, feedback is available.

    Cortex-wide BOLD fMRI activity reflects locally-recorded slow oscillation-associated calcium waves

    Miriam Schwalm, Florian Schmid ... Albrecht Stroh
    Locally recorded calcium events related to slow wave activity show a global cortical fMRI BOLD correlate, establishing a direct relation between a basic neurophysiological signal and the macroscopic perspective of pre-clinical fMRI.

    Imaging single-cell blood flow in the smallest to largest vessels in the living retina

    Aby Joseph, Andres Guevara-Torres, Jesse Schallek
    By using a specialized camera that corrects for eye blur, millions of single-blood-cells are imaged, and their speed measured, as they travel through the largest-to-smallest vessels of the retina.
