    Regulation of presynaptic Ca2+ channel abundance at active zones through a balance of delivery and turnover

    Karen L Cunningham, Chad W Sauvola ... J Troy Littleton
    Voltage-gated calcium channel delivery to synaptic active zones (AZs) occurs broadly across the population, correlates with AZ size, and is regulated by α2δ, while channel recycling is promoted by new delivery to generate an upper limit on AZ accumulation.

    Mapping odorant sensitivities reveals a sparse but structured representation of olfactory chemical space by sensory input to the mouse olfactory bulb

    Shawn D Burton, Audrey Brown ... Matt Wachowiak
    Large-scale mapping of sensory input to the mouse olfactory bulb reveals exceptionally narrow tuning of olfactory receptor input to glomeruli and defines a functional map of glomerular sensitivities that is structured with respect to olfactory chemical space.

    Impaired astrocytic Ca2+ signaling in awake-behaving Alzheimer’s disease transgenic mice

    Knut Sindre Åbjørsbråten, Gry HE Syverstad Skaaraas ... Rune Enger
    Noradrenaline-mediated astrocytic Ca2+ signaling in behavior is reduced in awake-behaving tg-ArcSwe Alzheimer's disease transgenic mice.

    Intracerebral mechanisms explaining the impact of incidental feedback on mood state and risky choice

    Romane Cecchi, Fabien Vinckier ... Julien Bastin
    Invasive electrophysiological recordings from the human brain reveal that different mood levels translate into different brain states that predispose subjects to make risky or safe decisions.

    Structural motifs for subtype-specific pH-sensitive gating of vertebrate otopetrin proton channels

    Bochuan Teng, Joshua P Kaplan ... Emily R Liman
    The sour receptor, OTOP1, and related proton channel OTOP3 are steeply activated by extracellular protons while OTOP2 is active over a broad pH range and differences in gating are partly attributed to extracellular domains.

    Brain-wide analysis of the supraspinal connectome reveals anatomical correlates to functional recovery after spinal injury

    Zimei Wang, Adam Romanski ... Murray G Blackmore
    Three-dimensional imaging and automated, brain-wide cell counting yield new insight into the diversity of neurons that connect the brain to the spinal cord and their different sensitivity to spinal cord damage.

    Therapeutic deep brain stimulation disrupts movement-related subthalamic nucleus activity in parkinsonian mice

    Jonathan S Schor, Isabelle Gonzalez Montalvo ... Alexandra B Nelson
    In a mouse model of Parkinson's disease, deep brain stimulation of the subthalamic nucleus disrupts movement-related neural activity in parallel with relieving motor symptoms.

    Label-free three-photon imaging of intact human cerebral organoids for tracking early events in brain development and deficits in Rett syndrome

    Murat Yildirim, Chloe Delepine ... Mriganka Sur
    Label-free three-photon imaging of whole, uncleared intact organoids generated from Rett syndrome patients show shorter migration distances and slower migration speeds of mutant radially migrating neurons with more tortuous trajectories.

    Sequential addition of neuronal stem cell temporal cohorts generates a feed-forward circuit in the Drosophila larval nerve cord

    Yi-wen Wang, Chris C Wreden ... Ellie Heckscher
    A newly identified pattern of circuit assembly shows connectivity between small groups of neurons born in tight time windows from different stem cells, with outputs from one lineage born before inputs from other lineages.

    Homotopic contralesional excitation suppresses spontaneous circuit repair and global network reconnections following ischemic stroke

    Annie R Bice, Qingli Xiao ... Adam Q Bauer
    Excitation of contralesional cortex after stroke suppresses the expression of genes related to plastic neuronal reintegration and accordingly modulates perilesional remodeling and functional network communication at local and global scales.
