Functional magnetic resonance imaging (fMRI) techniques have great potential for identifying which neural structures are involved in the control of goal-directed reaching movements. However, fMRI techniques alone are not capable of probing the neural mechanisms involved in acquisition of novel motor behaviors because such studies require that the moving limb be perturbed in a controlled fashion. We outline a plan to design and develop a non-metallic, pneumatically actuated tool that, along with systems identification techniques and functional magnetic resonance imaging (fMRI), will characterize and quantify how the human central nervous system uses sensory information during practice-based motor learning.

Nuclear magnetic resonance phosphorus spectroscopy (NMRS) is a method of measuring the mineral content of bone as a diagnostic tool for osteoporosis. A description is given of the design and construction of a low-field spectrometer for the human wrist. It uses a small-size permanent magnet of neodymium-iron-boron. The questions of whether a low-field spectrometer is sensitive enough to measure the phosphorus mineral content of bone and to what extent the phosphorus in soft tissue affects the measurement of bone mass are discussed
