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

    Andreas A Kardamakis et al.
    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.

    Role of the visual experience-dependent nascent proteome in neuronal plasticity

    Han-Hsuan Liu et al.
    A screen of visual-experience induced changes in newly-synthesized proteins in Xenopus optic tectum identifies unexpected candidate plasticity proteins.

    An NMDA receptor-dependent mechanism for subcellular segregation of sensory inputs in the tadpole optic tectum

    Ali S Hamodi et al.
    An activity-dependent mechanism sculpts subcellular segregation of sensory inputs.

    A cellular mechanism for inverse effectiveness in multisensory integration

    Torrey LS Truszkowski et al.
    Building on previous work (Felch et al., 2016), it is shown that inverse effectiveness, a central property of multisensory integration, in the optic tectum is mediated by the activation of NMDA-type glutamate receptors, resulting in a response greater than the sum of responses to each individual sensory modality.

    Stochastic cell-cycle entry and cell-state-dependent fate outputs of injury-reactivated tectal radial glia in zebrafish

    Shuguang Yu, Jie He
    The analysis of injury-reactivated tectal radial glia in zebrafish reveals a stochastic cell-cycle entry and cell-state-dependent regulation of the balance between neurogenesis and gliogenesis.

    Pretectal neurons control hunting behaviour

    Paride Antinucci et al.
    A discrete population of genetically accessible pretectal neurons controls visually guided hunting behaviour in larval zebrafish.

    Multivariate analysis of electrophysiological diversity of Xenopus visual neurons during development and plasticity

    Christopher M Ciarleglio et al.
    The diversity of electrophysiological phenotypes of neurons in a functional network increases over development, but can be modulated, and even reduced by sensory experience; allowing them to adapt to a changing and growing brain.
    1. Neuroscience

    A time-stamp mechanism may provide temporal information necessary for egocentric to allocentric spatial transformations

    Avner Wallach et al.
    A novel neural mechanism for precise, unbiased estimation of time intervals in the thalamus of electric fish is likely used for computing distance between object encounters.
    1. Neuroscience

    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.
    1. Neuroscience

    Multisensory integration in the developing tectum is constrained by the balance of excitation and inhibition

    Daniel L Felch et al.
    During development, the Xenopus brain improves its ability to discern specific time intervals between sensory inputs of different modalities via the maturation of inhibitory circuits.
