    Fundamental constraints in synchronous muscle limit superfast motor control in vertebrates

    Andrew F Mead et al.
    Vertebrate superfast muscles employ similar excitation–contraction strategies but distinct myosin heavy chain genes to allow superfast performance, revealing a maximum speed that cannot be overcome without sacrificing neural control.

    General features of the retinal connectome determine the computation of motion anticipation

    Jamie Johnston, Leon Lagnado
    Feedforward inhibition generates motion anticipation by selectively decreasing sensitivity to a stimulus as it moves across the latter part of a retinal ganglion cell's receptive field.
  1. Point of View: Science, art, society and Klimt’s University of Vienna paintings

    Alberto E Pereda
    A set of paintings by Gustav Klimt highlights ongoing tensions in the relationships between art, science and society.

    Retinal oxygen supply shaped the functional evolution of the vertebrate eye

    Christian Damsgaard et al.
    Multiple respiratory and vascular mechanisms have recurrently evolved across the vertebrates to alleviate the oxygen diffusion limitations inherent to the morphology of the retina.

    Neural activity in a hippocampus-like region of the teleost pallium is associated with active sensing and navigation

    Haleh Fotowat et al.
    Sparse firing in a hippocampus-like structure of the teleost telencephalon is linked to spatial navigation and active sensing.

    AMPA receptor mediated synaptic excitation drives state-dependent bursting in Purkinje neurons of zebrafish larvae

    Mohini Sengupta, Vatsala Thirumalai
    In vivo recordings in unanesthetized zebrafish larvae show that Purkinje neurons have two stable membrane potential states and that climbing fiber inputs can toggle them to up states during motor episodes.

    Presynaptic morphology and vesicular composition determine vesicle dynamics in mouse central synapses

    Laurent Guillaud et al.
    In central synapses, the mobility and supply of synaptic vesicles are determined by two independent biological factors: the morphological and structural organization of nerve terminals and the molecular signature of vesicles.

    Non-classical amine recognition evolved in a large clade of olfactory receptors

    Qian Li et al.
    Fish trace amine-associated receptors evolved a novel structural motif that enables the detection of chemically diverse amine odors in a non-canonical 'inverted' orientation.

    A dedicated visual pathway for prey detection in larval zebrafish

    Julia L Semmelhack et al.
    A subset of retinal ganglion cells respond specifically to small moving objects and project to a visual area that plays a key role in prey capture behavior.

    An arbitrary-spectrum spatial visual stimulator for vision research

    Katrin Franke et al.
    Towards a community effort, we here present a flexible yet standardised visual stimulator design based on open hardware and software.
