Embodiment in the Mammalian Whisker System: How Anatomy and Biomechanics Facilitate Sensation and Movement

Description:

The rat whisker system has been a longstanding and fruitful model system for sensory neuroscience, because of its status as an œexpert active sensing system, and many open avenues of research still remain. One large-scale goal of the field is to œclose the loop from sensation to movement, modeling how...

The Roles of Primary Motor Cortex and Dorsal Premotor Cortex in Planning and Executing Movements under Uncertainty

Description:

Each movement we make represents the final output of complex processes in the nervous system. Studies of motor control often attempt to minimize further complication by using controlled environments to generate repeated movements. However, in natural situations, the motor system faces the much more complicated task of interacting with an...

Development of novel citric-based biomaterials for treatment of diabetes and its complications

Description:

Diabetes mellitus is a metabolic disease characterized by the abnormal high blood glucose of patients. The defects in the hormonal regulation, including impaired insulin secretion, insulin action, or the combination of the two are usually the causes of such a disease. The elevated blood glucose also leads to a wide...

3D Printing and Extracellular Matrix Culture Strategies for Liver and Intrahepatic Biliary Tree Tissue Engineering

Description:

Currently, the only treatment for end stage liver disease is transplantation, of which there is a critical shortage of available donor tissue. Recent developments in 3D printing have greatly accelerated progress in the field of liver tissue engineering. A variety of 3D printing and additive manufacturing techniques show great promise...

An Investigation of the Musculoskeletal Changes in the Hand After Chronic Hemiparetic Stroke and Their Impact on Hand Opening: Using Integrated Experimental and Computer Simulation Methods

Description:

Up to two thirds of individuals with chronic hemiparetic stroke suffer life-long residual impairments to their paretic hands, affecting their independence and quality of life. These impairments stem initially from losses of direct corticospinal projections that result in an increased reliance on indirect bulbospinal pathways. This reliance on the indirect...

Sensing with Whiskers: From Geometry and Mechanics to the Statistics of the Array

Description:

The rodent whisker system is a widely used model to study the sense of touch. Its neuroanatomy parallels that of the human, but its mechanics are vastly simplified compared to that of the human tactile system. Just like other modalities with complex sensor accessory structures, the geometry, mechanics, and material...

NEURAL AND BIOMECHANICAL MECHANISMS OF MOVEMENT IMPAIRMENT IN STROKE SURVIVORS

Description:

Many stroke survivors are left with residual movement impairments. Treating these impairments has proven difficult, because it is often unclear which mechanisms drive movement impairment. While the exact mechanisms are still uncertain, at present, evidence suggests that neuromuscular function is disrupted in two key domains following stroke: muscle biomechanics, and...

A Representation of Energy in Sensorimotor Integration and Control

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...

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

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,...

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

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...

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

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...

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...

Investigation of the Effects of Caffeine Using Calibrated BOLD

Description:

Caffeine is the most widely consumed methylxanthine, primarily found in beverages. As a nonspecific antagonist to adenosine, caffeine binds to both A1 and A2A adenosine receptors to increase neural activity and decrease cerebral blood flow, which allows it to alter neurovascular coupling. However, there has been much debate about the...
