Journal ArticleDOI
Recruitment of the proximal and distal portions of the cat semitendinosus during running and jumping
Journal ArticleDOI
Innervation patterns in the cat tibialis anterior six months after self-reinnervation.
TL;DR: The spatial distribution of fibers belonging to a single motor unit was analyzed in 10 motor units from the tibialis anterior of the cat 6 months after denervation and self‐reinnervation of the anterior (superficial) compartment of the muscle.
Journal ArticleDOI
Basal and evoked levels of bioassayable growth hormone are altered by hindlimb unloading.

TL;DR: The data suggest that BGH synthesis and release from the pituitary are sensitive both to chronically reduced neuromuscular loading and to acute changes in neuromUScular activation, independent of changes in other circulating hormones.
Journal ArticleDOI
Spinal neuronal activation during locomotor-like activity enabled by epidural stimulation and 5-hydroxytryptamine agonists in spinal rats

TL;DR: In this paper, the authors used c-fos (an activity-dependent marker) to identify active interneurons and motoneurons in the lumbar spinal cord of adult spinal rats during a 30-minute bout of bipedal stepping.
Journal Article
Succinate dehydrogenase activity in rat dorsolateral ventral horn motoneurons at L6 after spaceflight and recovery.

TL;DR: Moderate-sized motoneurons, most likely innervating fibers in high-oxidative muscles, are responsive to the microgravity environment, and are indicated to be responsive to spaceflight and recovery on Earth.
