    Functional MRI: Making connections in the brain

    Alex TL Leong, Ed X Wu
    Simultaneous measurements of neuronal activity and fMRI signals in the rat brain have shed new light on the origins of resting-state fMRI connectivity networks.

    Test of the 'glymphatic' hypothesis demonstrates diffusive and aquaporin-4-independent solute transport in rodent brain parenchyma

    Alex J Smith et al.
    Solute movement in brain extracellular space is determined by solute diffusion, and does not depend on convection or aquaporin-4 expression as predicted by the glymphatic mechanism.

    Cell type-specific long-range connections of basal forebrain circuit

    Johnny Phong Do et al.
    Whole-brain mapping of the basal forebrain circuits reveals a connection diagram with highly convergent inputs and divergent outputs.

    Ultrastructural analysis of adult mouse neocortex comparing aldehyde perfusion with cryo fixation

    Natalya Korogod et al.
    Snap-freezing of brain tissue reveals its true structure-showing that cells are less squashed together, and the connections between neurons are less enclosed than previously thought.

    Automatic discovery of cell types and microcircuitry from neural connectomics

    Eric Jonas, Konrad Kording
    An algorithm for analysing brain connectivity data identifies cell types and connections in simple (C. elegans) and complex (mouse) nervous systems, and can even resolve structure and connectivity in a man-made microprocessor.

    Reciprocal synapses between mushroom body and dopamine neurons form a positive feedback loop required for learning

    Isaac Cervantes-Sandoval et al.
    Structural and functional analysis of axonal-axonal reciprocal connections between dopamine neurons and Kenyon cells provides insight into the brain computations for normal associative olfactory learning.

    Synaptic organization of the Drosophila antennal lobe and its regulation by the Teneurins

    Timothy J Mosca, Liqun Luo
    A comprehensive synapse-level analysis of a fly central-brain region has led to the identification of molecules that are necessary for mediating the normal density of connections.

    A simple generative model of the mouse mesoscale connectome

    Sid Henriksen et al.
    A realistic model of the connections between local populations of neurons in the adult mouse brain can be constructed based on just two biologically plausible rules.

    Brain and Behavior: Assessing reproducibility in association studies

    Hugo Schnack
    Research that links brain structure with behavior needs more data, better analyses, and more intelligent approaches.
