    The recovery of standing and locomotion after spinal cord injury does not require task-specific training

    Jonathan Harnie et al.
    Restoring locomotion after complete spinal cord injury does not require locomotor training, only the return of sufficient excitability within neurons of the spinal cord.

    Cannabinoids modulate associative cerebellar learning via alterations in behavioral state

    Catarina Albergaria et al.
    Cannabinoid receptors modulate cerebellar learning, not through direct effects on synaptic plasticity, but as a secondary consequence of their modulation of behavioral state.

    Spinal microcircuits comprising dI3 interneurons are necessary for motor functional recovery following spinal cord transection

    Tuan V Bui et al.
    A genetically-defined population of spinal interneurons is reciprocally connected with spinal locomotor circuits and mediates recovery of locomotor function following spinal cord transection.

    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.

    Control of voluntary and optogenetically perturbed locomotion by spike rate and timing of neurons of the mouse cerebellar nuclei

    Rashmi Sarnaik, Indira M Raman
    Stride-related modulated firing by neurons of the cerebellar nuclei is required for smooth execution of practiced locomotion and persists more easily with synchronous than asynchronous Purkinje-mediated inhibition.

    A quantitative framework for whole-body coordination reveals specific deficits in freely walking ataxic mice

    Ana S Machado et al.
    Analysis of 3D paw kinematics and whole-body coordination in freely walking mice isolates specific features of gait ataxia and supports the hypothesis that the cerebellum provides an internal forward model for motor control.

    Cytotoxic T-cells mediate exercise-induced reductions in tumor growth

    Helene Rundqvist et al.
    Exercise can induce metabolic changes that strikingly impact cytotoxic T cell function and in turn affect cancer progression.

    Synchronous activity patterns in the dentate gyrus during immobility

    Martin Pofahl et al.
    Two-photon in vivo calcium imaging reveals short time-scale, synchronous and sparse population activity in dentate gyrus that replays place-related information, and is important for formation of dentate-dependent spatial memory.

    A virtual burrow assay for head–fixed mice measures habituation, discrimination, exploration and avoidance without training

    Andrew JP Fink et al.
    A naturalistic assay for head-fixed mice permits observation of a diverse set of innate and learned behaviors without requiring any training.

    The biphasic and age-dependent impact of klotho on hallmarks of aging and skeletal muscle function

    Zachary Clemens et al.
    Transcriptomic analysis using a novel information-based network entropy approach provides mechanistic insights into the ability of Klotho to successfully ameliorate age-related sarcopenia in old mice, but not oldest-old mice.
