Neural Control of Sickness Behavior
… to the central nervous system, the underlying control mechanisms for this response have not been elucidated. The goal of this work was to quantitatively characterize the many phenotypes associated with infection-induced sickness and to identify neural substrates responsible for the induction …

Sympathetic neural control of renal blood flow
… activity (RSNA) plays an important role in the control of renal hemodynamics and function. It achieves this control by changing the mean levels of activity and/or changing the power of the distinct frequencies that comprise this mean activity. My studies, presented in four parts, investigate how …

Sex differences in the neural control of muscle
… reveals how biomechanical factors may impact neural control. Since males and females are more comparable with respect to strength in the lower limb, it allows for a determination of whether potential sex-differences in neural control exist without large differences in biomechanics. …

Real time evolutionary algorithms in robotic neural control systems.
… Algorithm (RTEA) to optimise an Artificial Neural Network (ANN) on-line (in this context on-line means while it is in use). Traditionally, Evolutionary Algorithms (Genetic Algorithms, Evolutionary Strategies and Evolutionary Programming) have been used to train networks before use - that is …

Renal failure and the neural control of the kidney
… in a dysregulation of basal RSNA and reflexly controlled RSNA by the high and low pressure baroreceptors. Baroreflex gain curves for both RSNA and HR were generated in control and RF rats. This study clearly showed a blunted high-pressure baroreflex in RF rats, an impairment which was almost …

Sympathetic Neural Control of Inflammation by ADRB2-Mediated IL-10 Secretion
… a novel role for the beta2-ADR (ADRB2) in controlling inflammation. NE suppresses pro-inflammatory cytokine secretion from primary macrophages in response to multiple TLR agonists, and ADRB2 signaling enhances early induction of IL-10. In addition to its in vitro affects, I have shown that …

Amino acid transmitters and the neural control of feeding and energy homeostasis
Consuming the correct number of calories to maintain a healthy bodyweight is a delicate balancing act between intake and energy expenditure, and humans in modern society seem to have a keen knack for throwing the balance off-center. In the U.S. alone, more than 1/3 of adults are obese based on the …

The Exploration of KNN-based Neural Control of Pneumatically Actuated Artificial Muscle
… individually; what actuation is the user controlling, and how the user is controlling these actuators. In this thesis, we present the groundwork of addressing both of these problems through a parallel effort of prototyping, modelling, and experimenting for a promising method of neural …

Intrinsic Neural Control of Propulsion, Storage and Slow Transit in the Large Intestine.
… of gastrointestinal research, a new intrinsic neural reflex that appears to underlie slow transit and accommodation in the large bowel. Using electrophysiological techniques we demonstrate that circumferential stretch generates ongoing oral excitatory and anal inhibitory junction potentials in …

Hierarchical neural control of human postural balance and bipedal walking in sagittal plane
… been known to be a central part in human motion control and execution. However, engineering descriptions of the system, especially in relation to lower body motion, have been very limited. This thesis proposes an integrated hierarchical neural model of sagittal planar human postural balance and …

A statistical framework for the analysis of neural control of movement with aging and other clinical applications
… effects of aging on biological signals for motor control and to develop a methodology to classify aging and stroke populations. The methodological approach investigated the influence on correlated activity (coherence) between electroencephalogram (EEG) and electromyogram (EMG) signals into senior …

Investigation of a multi-layer perceptron network to model and control a non-linear system.
… implementation of an on-line optimal predictive controller incorporating a neural network model of a non-linear process. The scheme is based on a Multi-Layer Perceptron neural net-work as a modelling tool for a real non-linear, dual tank, liquid level process. A neural network process model is …

An agonist-antagonist myoneural interface for proprioception from a neurally-controlled prosthesis
… proprioception, and is essential to human motor control. In the many attempts to create human-mechatronic interactions, there is still no robust, repeatable methodology to reflect proprioceptive information from a synthetic device onto the nervous system. As a solution to this shortcoming, I …

Human physical interaction with a circular constraint
… limb crank turning experiment to study the human controller used to manage physical interaction. Subjects turned a crank with and without visual feedback, in two directions (clockwise and counterclockwise), and in three speed conditions (slow (0.075 rev/s), medium (0.5 rev/s), and fast (2 rev/s)). …

Sensory feedback and control of leg-substrate interactions in insects and robots
… feedback plays an important role in adaptive control of insect leg movements as required, for example, in agile locomotion over irregular terrain. Functionally, insect legs are not just effectors--they are also sophisticated sensory devices that provide the nervous system with a great deal of …

Estimating output torque via amplitude estimation and neural drive : a high-density sEMG study
… within this field is improving user-interface control. An established approach for improving user-interface control is neural control interfaces derived from surface electromyography (sEMG). This thesis presents an exploration of output joint torque estimation using high density surface …
