Assessment and modulation of essential tremor using peripheral-nerve stimulation
… such as medications and thalamic deep brain stimulation, have not been adopted broadly because of the invasiveness of the treatments and their lack of efficacy. To address these limitations, the objectives of this PhD dissertation are (1) to quantitatively assess tremor movement, and (2) to …

MRI Safety Concerns: Anatomy Impacts on Radiofrequency Induced Heating and Implant Impacts on Gradient Induced Peripheral Nerve Stimulation
… (RF) induced heating and gradient induced peripheral nerve stimulation (PNS) are two typical safety concerns. Although many literatures have found the importance of them, they are not fully investigated. In this dissertation, the impact of anatomy on the RF-induced heating and the impact of …

Strategies for optogenetic stimulation of deep tissue peripheral nerves
… neurophysiological pathways in the central and peripheral nervous systems. Optogenetics refers to the transduction of mammalian cells with a light-sensitive transmembrane protein, called an opsin, such that illumination of the target tissue initiates depolarization; in the case of a neuron, …

Modeling the Muscle Relaxation Response to Succinylcholine for the Purpose of Controller Design.
… the evoked response (twitch) to periodic peripheral nerve stimulation (Katz & Katz, 1975).Present procedures for the administration of muscle relaxants may be improved in several ways. Patient variability in response is poorly managed in the current techniques, even though this variability …

Development Of Carbon Based Neural Interface For Neural Stimulation/recording And Neurotransmitter Detection
<p>Electrical stimulation and recording of neural cells have been widely used in basic neuroscience studies, neural prostheses, and clinical therapies. Stable neural interfaces that effectively communicate with the nervous system via electrodes are of great significance. Recently, flexible neural …

Electric stimulation parameters for an epi-retinal prosthesis
… obstacle to the success of this approach. Stimulation of ganglion cell axons-which lie in the optic nerve fiber layer between stimulating electrodes and their intended targets, and which originate from a relatively diffuse peripheral region-would probably convey the perception of a …

New approaches to diagnostic imaging: Magnetic particle imaging for human functional neuroimaging and short mid-field MRI magnet design
… safety aspects of MPI, specifically focusing on peripheral nerve stimulation (PNS) induced by the 25 kHz magnetic excitation fields used in MPI. Because this is a higher frequency than those used by MRI gradients, threshold data at this frequency are lacking. This thesis measures the PNS …

MODELING INTERFASCICULAR INTERFACES FOR PERIPHERAL NERVES
<p>Stimulation electrodes with higher levels of selectivity than currently available are required to restore limb function, especially in the upper extremity. One strategy to increase the selectivity of an electrode is to move it closer to the target axons. A balance between selectivity and …
