Neurophysiology of Movement Laboratory Carlson 202G Department of Integrative Physiology University of Colorado Boulder, CO 80309-0354 phone: 303-492-4965 fax: 303-492-6778

Research Interests

1. Aging - adaptations in neuromuscular properties with advancing age: (a) association between indices of health status and neuromuscular performance in healthy older adults; (b) PET-based imaging of glucose uptake by muscle during fatiguing contractions; (c) modulation of spinal reflex pathways during the performance of steady contractions.


2. Handedness - control strategies used by left-handed individuals as indicated by motor unit recordings.


3. Multiple sclerosis - the associations between MRI-based estimates of brain structure and function with the fatigue reported by individuals with multiple sclerosis.
