    Spinal V2b neurons reveal a role for ipsilateral inhibition in speed control

    Rebecca A Callahan et al.
    Two anatomically and genetically distinct subtypes of spinal V2b neurons provide inhibition onto motor circuits and serve as a brake on locomotor speed.

    Remodeling of lumbar motor circuitry remote to a thoracic spinal cord injury promotes locomotor recovery

    Ying Wang et al.
    Retrograde transport of NT-3 stimulated the reorganization of lumbar neural circuitry and synaptic connectivity remote to a thoracic SCI, along with improved behavioral recovery.

    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.

    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.

    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.

    Defined neuronal populations drive fatal phenotype in a mouse model of Leigh syndrome

    Irene Bolea et al.
    Glutamatergic brainstem neurons drive motor and respiratory deficits, and GABAergic basal ganglia neurons cause hypothermia and fatal epileptic events, in a model of mitochondrial disease.

    Activity dynamics of amygdala GABAergic neurons during cataplexy of narcolepsy

    Ying Sun et al.
    Deep brain calcium imaging reveals the abnormal neuronal activity patterns of the amygdala GABAergic neurons in an animal model of human sleep disorder narcolepsy.
