Abstract:

Selective stimulation and conduction block of specific nerve fibers has been a major area of research in neuroscience. The potential clinical and neurophysiological applications have warranted reliable techniques for transiently blocking conduction through nerves. High Frequency Alternating Current (HFAC) waveforms have been found to induce a reversible and repeatable block in peripheral nerves; however the effect of these waveforms on the neural activity of individual fiber types is currently unknown. Understanding this effect is critical if clinical applications are to be pursued. This disse

Abstract:

Central white matter and peripheral nerves function by conducting action potentials, which rely on the presence of transmembrane potentials generated by ion gradients. The maintenance of these transmembrane potentials is the main energy-dependent process in the nervous system. In this thesis I investigated the ability of endogenous glycogen to support the energy requirements of nervous tissue and the role of lactate in this process. Glycogen in the CNS is located in astrocytes but is capable of supporting axonal conduction, implying axon-glial metabolic interactions. These interactions were in

Abstract:

Auditory physiology is nearly unique in the human body because of its small-diameter neurons. When considering a single node on one neuron, the number of channels is very small, so ion fluxes exhibit randomness. Hodgkin and Huxley, in 1952, set forth a system of Ordinary Differential Equations (ODEs) to track the flow of ions in a squid motor neuron, based on a circuit analogy for electric current. This formalism for modeling is still in use today and is useful because coefficients can be directly measured. To measure auditory properties of Firing Efficiency (FE) and Post Stimulus Time (PST),

Repeatability and quality data recordings are essential and thus dictate the requirements of the laboratory setup and processes listed above.

While very precise equipment is required to record the low voltage bio-potentials, noisy electronic equipment and wires surrounding the work area provide high levels of interference.

It was initially hypothesised that the CAP waveform and SNN contained components produced by the local action currents generated at the peripheral ends of the type I primary afferent neurones, and that changes in the

Abstract:

Current cochlear implant systems use fast pulsatile stimulation to deliver the temporal modulations of speech and to, potentially, improve the neural representation of such modulations by restoring the independence of neural firing. The realization of these benefits may vary with other pulse rate-dependent temporal interactions that occur at the neural membrane, e.g., per(i)stimulatory adaptation and its post-stimulatory or forward masking effects.

Effective cochlear implant fitting (or programming) is essential for providing good hearing outcomes, yet it is a subjective and error-prone task. The initial objective of this research was to automate the procedure using the auditory nerve electrically evoked compound action potential (the ECAP) and machine intelligence. The Nucleus?? cochlear implant measures the ECAP via its Neural Response Telemetry (NRT) system.

We study a system of spatially discrete FitzHugh-Nagumo equations, which are nonlinear differential-difference equations on an infinite one-dimensional lattice. These equations are used as a model of impulse propagation in nerve cells. We employ McKean's caricature of the cubic as our nonlinearity, which allows us to reduce the nonlinear problem into a linear inhomogeneous problem. We find exact solutions for standing waves, which are steady states of the system. We derive formulas for all 1-pulse solutions. We determine the range of parameter values that allow for the existence of standing wa

Abstract:

Secreted by adipose tissue, leptin acts as a signal of energy reserve status, and acts in the brain as a negative feedback mechanism to suppress food intake and increase energy expenditure, the net effect of which is maintenance of energy homeostasis. In addition to its role as a satiety factor, leptin has widespread autonomic effects, increasing sympathetic tone to a variety of tissues, including those involved in arterial pressure regulation. Thus, leptin has been implicated as a critical link between obesity and hypertension. However, the specific mechanisms whereby leptin elicits its diver

Abstract:

It is important to have better evaluation and understanding of the motor neuron physiology, with the goal to early and objectively diagnose and treat patients with neurodegenerative pathologies. The Compound Muscle Action Potential (CMAP) scan is a non-invasive diagnosis technique for neurodegenerative pathologies, such as ALS, and enables a quick analysis of the muscle action potentials in response to motor nerve stimulation. This work aims to study the influence of different pulse modulated waveforms in peripheral nerve excitability by CMAP scan technique on healthy subjects. A total of 13

Abstract:

<div>Electrical nerve stimulation (ENS) is an emerging therapy for many neurological disorders. Compared with conventional one-way stimulations, closed-loop ENS approaches increase the stimulation efficacy and minimize patient's discomfort by constantly adjusting the stimulation parameters according to the feedback biomarkers from patients. Wireless neurostimulation devices capable of both stimulation and telemetry of recorded physiological signals are welcome for closed-loop ENS systems to improve the quality and reduce the costs of treatments, and real-time digital signal processing (DSP) en

Abstract:

Indiana University-Purdue University Indianapolis (IUPUI)<br>Nerve growth factor (NGF) is a neurotrophin upregulated with injury and inflammation. Peripheral administration of NGF causes hyperalgesia and allodynia in animals. Blocking NGF signaling reverses these effects. At the cellular level, chronic exposure of sensory neurons to NGF enhances expression the neurotransmitter, calcitonin gene-related peptide (CGRP). Acute exposure to NGF increases capsaicin-evoked CGRP release from sensory neurons in culture. Thus, NGF increases peptide release from neurons by: (1) increasing expression of pe

Abstract:

Dissertation submitted to the Faculty of Health Sciences, University of the Witwatersrand , Johannesburg, in fulfillment of the requirements for the degree of Master of Science in Medicine, Johannesburg, 2011<br>HIV-associated sensory neuropathy (HIV-SN) is a common complication of HIV infection and its treatment with dideoxynucleoside drugs such as stavudine. Pain is a symptom in about 75% of cases of HIV-SN. The aim of this study was to set up the intraepidermal nerve fibre density (IENFD) quantification technique in a South African Laboratory and then to use this technique to investigate wh
