In the central nervous system, alpha-motor neurons play a key role in the chain that results in muscles producing force. A new non-invasive technique to measure the electrical activity involved with force production called High Density Surface Electromyography (HDsEMG) has been proven to be effective in providing novel clinical information on the way(More)
The distribution of motoneurons in the lumbar spinal cord (spinal segments 8-10) of the clawed toad, Xenopus laevis, was studied with the horseradish peroxidase technique. In a total of 13 different hind limb muscles this tracer was applied in a slow-release gel. Motoneurons innervating a particular hind limb muscle were clustered in longitudinally arranged(More)
Proceedings of the 52 nd European Study Group with Industry Preface Mathematics has intrinsic beauty, but it can also be fruitfully applied to solve concrete problems in the real world. This is the goal in Study Groups Mathematics with Industry. They originated in Oxford in the sixties, and have by now spread around the globe. The 52 nd European Study Group(More)
