    Sound exposure dynamically induces dopamine synthesis in cholinergic LOC efferents for feedback to auditory nerve fibers

    Jingjing Sherry Wu et al.
    Based on the animal’s recent history of sound exposure, cholinergic auditory brainstem neurons dynamically regulate dopamine synthesis for inhibitory feedback to the inner ear.

    Fast-spiking GABA circuit dynamics in the auditory cortex predict recovery of sensory processing following peripheral nerve damage

    Jennifer Resnik, Daniel B Polley
    Dynamic regulation of feedforward inhibition from parvalbumin-expressing inhibitory neurons is linked to the gradual restoration of cortical sensory processing following auditory nerve damage.

    In vivo assessment of the neural substrate linked with vocal imitation accuracy

    Julie Hamaide et al.
    Song learning accuracy can be predicted and traced in the structural properties of the brains of juvenile male zebra finches already at 20 days post-hatching.

    Motor context dominates output from purkinje cell functional regions during reflexive visuomotor behaviours

    Laura D Knogler et al.
    Purkinje cells of the cerebellum, a conserved vertebrate brain region important for sensorimotor integration, receive sensory and motor information from distinct input streams and are functionally clustered into modules reflecting the larval zebrafish's behavioral repertoire.

    Conserved and divergent development of brainstem vestibular and auditory nuclei

    Marcela Lipovsek, Richard JT Wingate
    The development of brainstem auditory nuclei echoes the divergent evolutionary history of amniote auditory systems.

    Signal integration at spherical bushy cells enhances representation of temporal structure but limits its range

    Christian Keine et al.
    Inhibition reduces the neuronal representation of acoustic signals to enhance temporal precision in the auditory brainstem.

    A neural circuit mechanism for regulating vocal variability during song learning in zebra finches

    Jonathan Garst-Orozco et al.
    By demonstrating song learning-related synaptic strengthening and pruning in the vocal control circuits of songbirds, and showing how such changes can reduce the sensitivity of the circuit to ‘noisy’ inputs, a simple neural circuit mechanism for regulating motor variability during motor skill learning is identified.

    Intercollicular commissural connections refine the representation of sound frequency and level in the auditory midbrain

    Llwyd David Orton, Adrian Rees
    Deactivation of one side of the auditory midbrain while recording in the other shows that the two sides cooperate in processing frequency and in enhancing the encoding of sound level.

    Disynaptic cerebrocerebellar pathways originating from multiple functionally distinct cortical areas

    Julia U Henschke, Janelle MP Pakan
    Anatomical projections from sensory, motor, and association cortex to the cerebellum are precisely mapped, including cortical-precerebellar connections and terminal organization, providing insight into how the cerebellum may utilize cortical information.
    1. Neuroscience

    Oligodendrocytes regulate presynaptic properties and neurotransmission through BDNF signaling in the mouse brainstem

    Miae Jang et al.
    Oligodendrocytes are actively engaged in the precise control of synaptic functions in the CNS through activity-dependent BDNF signaling.
