  1. A Representation of Energy in Sensorimotor Integration and Control

    Tb09j5821?file=thumbnail
    Description: Space, time and energy are the three most fundamental elements in our intellectual understanding of the physical world. Here, I found how these same elements also contribute to a stable and coherent representation that the motor system forms by combining information from different sensory sources, such as vision, touch and...

  2. The Refinement of Control Strategies for Cortically-Controlled Functional Electrical Stimulation

    Dj52w487g?file=thumbnail
    Description: Paralysis resulting from spinal cord injury (SCI) is devastating, dramatically reducing the independence of affected individuals. Currently, functional electrical stimulation (FES), controlled by a patient’s residual movements, is used clinically to restore a limited range of voluntary movement. However, if FES could be controlled using signals recorded from the brain,...

  3. The Roles of Primary Motor and Dorsal Premotor Cortex in Motor Adaptation

    Rv042t22c?file=thumbnail
    Description: The brain has a remarkable ability to rapidly adapt behavior. On the scale of development, the brain learns to control the complex dynamics of our limbs by forming and pruning synaptic connections. However, the motor system also learns on much shorter timescales, such as when learning to hit the bullseye...

  4. Step by Step: A Study of Step Length in Able-bodied Persons, Race walkers, and Persons with Amputation

    N583xv109?file=thumbnail
    Description: Step length is a common measurement taken during gait analyses. It allows one to determine asymmetries between the two legs, compare differences between subjects, and even compare intra-subject differences for changing parameters. Yet there has been little investigation of step length specifically and how it is modulated during walking. This...

  5. Cortical Activity and Reorganization in Sensorimotor Areas Following Central or Peripheral Injury to the Nervous System

    Sn009x962?file=thumbnail
    Description: The objective of this study was to investigate how brain plasticity can be expressed following injury to the nervous system. This plasticity can occur after either direct injury to the brain, such as in hemiparetic stroke, or injury to the peripheral nerves, such as in upper-limb amputation. In order to...

  6. Optimization of PROPELLER Methods for Quantitative MRI of Liver Cancer

    4m90dv63t?file=thumbnail
    Description: Hepatocellular carcinoma (HCC) is the most common primary malignant liver tumor, with the highest incidence in Asia. Developed countries, including the United States, have had an 80% increase in HCC incidence over the last 15-20 years. Magnetic Resonance Imaging (MRI) is a promising imaging modality with superior soft tissue...

  7. Neural and mechanical contributions to the regulation of human arm impedance in three degrees of freedom

    Qn59q411r?file=thumbnail
    Description: All forces applied to the human hand are transmitted through the arm to the trunk. Hence, the arm represents an important mechanical interface between the trunk and the environment. By regulating this interface in a task-appropriate manner, humans are able to interact with a wide range of tools and objects,...

  8. Respiratory Self-Gated Whole-Heart Coronary Magnetic Resonance Angiography

    Rn301156m?file=thumbnail
    Description: Coronary magnetic resonance angiography (MRA) is emerging as a promising method for noninvasive diagnosis of coronary artery diseases. Nonetheless, acquisition of large-coverage high-resolution coronary artery images requires free-breathing acquisition. Accurately measuring and correcting respiratory motion has been one of the major challenges to coronary MRA. Diaphragmatic navigator (NAV), the current...

  10. Tissue transglutaminase: A new method of facilitating hydrogel formation for cartilage regeneration and cartilage surface modification

    5t34sj78v?file=thumbnail
    Description: Articular cartilage is a type of connective tissue that protects the underlying bone from the compressive forces of daily activities. When cartilage is damaged via a traumatic event, chondral defects are formed and require medical intervention. However, current treatments are of inconsistent efficacy and only benefit a subset of patients....
