Changes in the exercise activation of diencephalic and brainstem cardiorespiratory areas after trainingRonaldo M Ichiyama
Department of Kinesiology, University of Illinois at Urbana-Champaign, Louise Freer Hall, 906 S. Goodwin Ave, Urbana, IL 61801, USA
Brain Res 947:225-33. 2002..These results are consistent with the concept that the nervous system changes its responses to a given level of exercise after training. These changes may also be related to perceived exertion...- Supraspinal locomotor centers do/do not contribute significantly to the hyperpnea of dynamic exercise in humansRonaldo M Ichiyama
University of California, Los Angeles, California, USA
J Appl Physiol 100:1745. 2006 
Training locomotor networksV Reggie Edgerton
Department of Physiological Science, University of California, Los Angeles, Los Angeles, CA 90095, USA
Brain Res Rev 57:241-54. 2008....- Epidural spinal cord stimulation plus quipazine administration enable stepping in complete spinal adult ratsYury P Gerasimenko
Department of Physiological Science, University of California, Los Angeles, CA 90095, USA
J Neurophysiol 98:2525-36. 2007..Quipazine potentiated the amplitude of these responses. The data suggest that there are fundamental differences in the circuitry that generates flexion and extension during locomotion... 
Step training reinforces specific spinal locomotor circuitry in adult spinal ratsRonaldo M Ichiyama
Institute of Membrane and Systems Biology, University of Leeds, Leeds, United Kingdom
J Neurosci 28:7370-5. 2008..These results suggest that training reinforces the efficacy of specific sensorimotor pathways, resulting in a more selective and stable network of neurons that controls locomotion...- Plasticity of spinal cord reflexes after a complete transection in adult rats: relationship to stepping abilityIgor Lavrov
Department of Physiological Science, University of California, Los Angeles, CA 90095-1527, USA
J Neurophysiol 96:1699-710. 2006..Combined, these findings support the view that restoration of polysynaptic spinal cord reflexes induced epidurally may provide a measure of functional restoration of spinal cord locomotor networks after ST... - Rehabilitative therapies after spinal cord injuryV Reggie Edgerton
Brain Research Institute, University of California, Los Angeles, Los Angeles, California, USA
J Neurotrauma 23:560-70. 2006.... - Supraspinal locomotor centers do/do not contribute significantly to the hyperpnea of dynamic exercise in humansFrederick L Eldridge
University of North Carolina at Chapel Hill, Chapel Hill, North Carolina, USA
J Appl Physiol 100:1743-7. 2006 - Spinal cord reflexes induced by epidural spinal cord stimulation in normal awake ratsYury P Gerasimenko
Department of Physiological Science, University of California, Los Angeles, CA 90095, USA
J Neurosci Methods 157:253-63. 2006..These data demonstrate the feasibility of using epidural stimulation for examining monosynaptic and polysynaptic pathways to motor pools associated with multiple muscles during movement and over a prolonged period... - Changes in motoneuron properties and synaptic inputs related to step training after spinal cord transection in ratsJeffrey C Petruska
Department of Neurobiology and Behavior, State University of New York at Stony Brook, Stony Brook, New York 11794 5230, USA
J Neurosci 27:4460-71. 2007.... - Dose dependence of the 5-HT agonist quipazine in facilitating spinal stepping in the rat with epidural stimulationRonaldo M Ichiyama
Department of Physiological Science, University of California, Los Angeles, CA 90095, United States
Neurosci Lett 438:281-5. 2008.... - Wheel running following spinal cord injury improves locomotor recovery and stimulates serotonergic fiber growthChristie Engesser-Cesar
Institute for Brain Aging and Dementia, University of California, Irvine, USA
Eur J Neurosci 25:1931-9. 2007..These observations suggest that improvement in function may be related to changes in serotonin fibers immediately caudal to the injury epicenter...
