    Physical basis of large microtubule aster growth

    Keisuke Ishihara et al.
    Autocatalytic growth of a microtubule polymer network allows extremely large egg cells to self-organize and divide rapidly.

    Neural evidence accumulation persists after choice to inform metacognitive judgments

    Peter R Murphy et al.
    Error detection is contingent on the continuation of evidence accumulation after choice commitment, and the speed and accuracy of this process are modulated by high-level signals from medial frontal cortex.

    Hippocampal neurogenesis enhancers promote forgetting of remote fear memory after hippocampal reactivation by retrieval

    Rie Ishikawa et al.
    Forgetting of remote fear memory is promoted by increased hippocampal neurogenesis only after hippocampal reactivation by long time memory retrieval.

    Light reintroduction after dark exposure reactivates plasticity in adults via perisynaptic activation of MMP-9

    Sachiko Murase et al.
    Light reintroduction (LRx) after dark exposure reactivates structural and functional plasticity in the adult mouse visual cortex by increasing the activity of MMP-9 at thalamo-cortical synapses.

    Cortex-dependent recovery of unassisted hindlimb locomotion after complete spinal cord injury in adult rats

    Anitha Manohar et al.
    After complete spinal transection in adult rats, careful combinations of pharmacological and physical therapies create a novel cortical sensorimotor circuit that may bypass the lesion through biomechanical coupling, allowing animals to recover unassisted hindlimb locomotion.

    Intramuscular Neurotrophin-3 normalizes low threshold spinal reflexes, reduces spasms and improves mobility after bilateral corticospinal tract injury in rats

    Claudia Kathe et al.
    Delayed intramuscular gene therapy with neurotrophin-3 after corticospinal tract injury reduces spasticity and improves locomotion by treating underlying causes of spasticity.

    Visual attention is available at a task-relevant location rapidly after a saccade

    Tao Yao et al.
    Spatial attention and saccadic processing co-ordinate to ensure that attention is available at a task-relevant location soon after the beginning of each eye fixation.

    Mitochondrial support of persistent presynaptic vesicle mobilization with age-dependent synaptic growth after LTP

    Heather L Smith et al.
    Three-dimensional electron microscopy (3DEM) demonstrates the dependence on presynaptic mitochondria for vesicle mobilization as dendritic spines are silently added at P15 or synapses are silently enlarged in adults after long-term potentiation.

    Childhood injury after a parental cancer diagnosis

    Ruoqing Chen et al.
    Children with a parent of cancer have a higher rate of hospital contact for injury, especially immediately after the cancer diagnosis.

    Synaptic up-scaling preserves motor circuit output after chronic, natural inactivity

    Joseph M Santin et al.
    Synaptic scaling maintains motor output from the respiratory network of bullfrogs after months of inactivity in the winter, providing evidence for homeostatic plasticity in response to large ecologically relevant perturbations in neuronal activity.
