    Purkinje cell neurotransmission patterns cerebellar basket cells into zonal modules defined by distinct pinceau sizes

    Joy Zhou et al.
    Targeted genetic silencing and reporter labeling reveal that Purkinje cell activity organizes cerebellar basket cells into zonal modules based on the sizes of their projections.

    Nanodomain coupling explains Ca2+ independence of transmitter release time course at a fast central synapse

    Itaru Arai, Peter Jonas
    Ca2+ channels and release sensors at a fast central synapse are tightly coupled, which minimizes the effect of extracellular Ca2+ concentration on the timing of transmitter release.

    Science Forum: The Human Cell Atlas

    Aviv Regev et al.
    Advances in techniques for analysing single cells and tissues have inspired an international effort to create comprehensive reference maps of all human cells - the fundamental units of life - as a basis for both understanding human health and diagnosing, monitoring and treating disease.

    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.

    Lamina-specific AMPA receptor dynamics following visual deprivation in vivo

    Han L Tan et al.
    Longitudinal imaging of synapses in the brain shows that sensory deprivation differentially modifies specific synapses within individual neurons across distinct layers of the sensory cortex.

    Altered functional connectivity during speech perception in congenital amusia

    Kyle Jasmin et al.
    Individuals with amusia, who have unreliable pitch processing, show decreased functional connectivity between right auditory and left language-related cortex during speech perception, demonstrating a neural basis for compensatory dimensional weighting.

    Spatiotemporal dynamics of multi-vesicular release is determined by heterogeneity of release sites within central synapses

    Dario Maschi, Vitaly A Klyachko
    Release site heterogeneity represents a previously unknown level of structural and functional organization within individual active zones in central synapses, which determines the spatiotemporal dynamics of multi-vesicular release.

    Noninvasive quantification of axon radii using diffusion MRI

    Jelle Veraart et al.
    Cell-specific architectural properties such as the axon diameter of the white matter of the human brain can be quantified accurately and non-invasively using diffusion magnetic resonance imaging.

    A primal role for the vestibular sense in the development of coordinated locomotion

    David E Ehrlich, David Schoppik
    Zebrafish use their sense of gravity and their cerebellum to coordinate the fin and body movements that, as they develop, allow them to better maintain balance as they climb.
