    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.

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

    Han-Hsuan Liu, Daniel B McClatchy ... Hollis T Cline
    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, Zhenyu Liu, Kara G Pratt
    An activity-dependent mechanism sculpts subcellular segregation of sensory inputs.
    1. Neuroscience

    Recurrent network interactions explain tectal response variability and experience-dependent behavior

    Asaph Zylbertal, Isaac H Bianco
    Recurrent interactions in the optic tectum underlie activity-dependent changes in network state that account for variability in sensory encoding and behavior.

    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.

    A cellular mechanism for inverse effectiveness in multisensory integration

    Torrey LS Truszkowski, Oscar A Carrillo ... Carlos D Aizenman
    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.

    Retinotectal circuitry of larval zebrafish is adapted to detection and pursuit of prey

    Dominique Förster, Thomas O Helmbrecht ... Herwig Baier
    The retinotectal map in zebrafish exhibits location-specific, functional specializations to match prey object movement in the visual field during the hunting sequence.
    1. Neuroscience

    Pretectal neurons control hunting behaviour

    Paride Antinucci, Mónica Folgueira, Isaac H Bianco
    A discrete population of genetically accessible pretectal neurons controls visually guided hunting behaviour in larval zebrafish.
    1. Neuroscience

    A dedicated visual pathway for prey detection in larval zebrafish

    Julia L Semmelhack, Joseph C Donovan ... Herwig Baier
    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

    Deletion of a kinesin I motor unmasks a mechanism of homeostatic branching control by neurotrophin-3

    Thomas O Auer, Tong Xiao ... Filippo Del Bene
    Disrupting synapse formation between the retina and the brain in zebrafish larvae-by eliminating the molecular motor Kif5A-triggers a compensatory increase in the branching of retinal axons aimed at restoring synapse number.
