Bi-modal Stimulator: Simultaneous electrical and acoustical stimulation to test a hypothesis for treating tinnitus

Subjective tinnitus is a sensation of sound without an external source. There is no clear understanding of the cause and pathology of tinnitus.<br/><br/>Literature suggests a combination of deafferentation of the tonotopic map , the Bayesian brain model, and the triple mode network, creating one combined hypothesis for tinnitus pathology. Based...

Kilohertz alternating current neuromodulation of the pudendal nerves: effects on the anal canal and anal sphincter in rats

The first two objectives were to establish which stimulation parameters of kilohertz frequency alternating current (KHFAC) neuromodulation influence the effectiveness of pudendal nerve block and its safety. The third aim was to determine whether KHFAC neuromodulation of the pudendal nerve can relax the pelvic musculature, including the anal...

Exploring Feasibility of FPGAs in Implantable Medical Devices

Implantable Medical Devices (IMDs) are deployed in patients to treat a range of medical conditions. Technological advancements have enabled manufacturers to fit IMDs with specialized hardware that accelerates compute-intensive medical therapies next to a software-run host processor. However, mostly hardware acceleration is found in the form of...

Towards CMUT for Neurostimulation: The Development of an Experimental Model for the Validation of Ultrasound Neuromodulation and Back-side Vent Etching for Low-Frequency CMUT Devices

Ultrasound (US) neurostimulation, the non-pharmacological, reversible excitation or inhibition of the nervous system using ultrasonic waves, is emerging as a high interest topic in neurostimulation research. In the current project, an attempt was made to demonstrate US neuromodulation in a Lumbricus Terrestris model of evoked compound action...
