    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.

    Offline impact of transcranial focused ultrasound on cortical activation in primates

    Lennart Verhagen et al.
    A new application of transcranial ultrasound safely modulates brain activation in primates for up to 2 hours after 40 seconds of stimulation.

    Fish-hunting cone snail venoms are a rich source of minimized ligands of the vertebrate insulin receptor

    Peter Ahorukomeye et al.
    The unique modus operandi of cone snail venom insulins provides new insight into insulin receptor activation and informs on the design of insulin analogs for the treatment of diabetes.

    High-order thalamic inputs to primary somatosensory cortex are stronger and longer lasting than cortical inputs

    Wanying Zhang, Randy M Bruno
    Secondary thalamic nuclei may provide stronger, longer-lasting input to superficial layers of primary sensory cortex than other cortical areas can.

    Humans strategically shift decision bias by flexibly adjusting sensory evidence accumulation

    Niels A Kloosterman et al.
    Decision-makers are able to intentionally control neural excitability to strategically bias sensory evidence accumulation towards the decision bound that maximizes reward within a given ecological context.

    Generality and opponency of rostromedial tegmental (RMTg) roles in valence processing

    Hao Li et al.
    Rostromedial tegmental neurons encode motivational valence and opponent responses across a wide range of affective stimulus modalities, while also driving dopamine inhibition and conditioned place aversion to aversive stimuli.

    Computational modeling of brainstem circuits controlling locomotor frequency and gait

    Jessica Ausborn et al.
    A new computational model of brainstem control of locomotor speed and gait was developed to reproduce and explain recent experimental data and propose predictions for subsequent experimental testing.

    The role of scaffold reshaping and disassembly in dynamin driven membrane fission

    Martina Pannuzzo et al.
    Computational modeling of a dynamin-constricted membrane neck can rank proposed shape changes of the helical scaffold in terms of their fission aptitude and elucidate the associated pathways.

    The conserved aspartate ring of MCU mediates MICU1 binding and regulation in the mitochondrial calcium uniporter complex

    Charles B Phillips et al.
    Biochemical analysis reveals molecular mechanisms underlying the activation of the mitochondrial Ca2+ uniporter by intracellular Ca2+ signals.
