The growing use of non-invasive brain stimulation in clinical applications reflects its capabilities to transiently modulate cortical excitability, motor and cognitive functions in ways not possible with other techniques. Neurological disorders represent t ...
A preferred frequency is identified, being usable to stimulate a neurological target within a mammalian body using at least one microelectrode positioned at or near the target. To establish efficient and effective stimulation, an impedance analyzer is prov ...
The use of nanowire crossbars to build devices with large storage capabilities is a very promising architectural paradigm for forthcoming nanoscale memory devices. However, this new type of memory devices raises questions regarding how to test their correc ...
Non-invasive brain stimulation has shown its potential to modulate brain plasticity in humans. Endeavour has been made to utilize brain stimulation in neurological diseases to enhance adaptive processes and prevent potential maladaptive ones. In stroke for ...
Direct electrical stimulation of the colon offers a promising approach for the induction of propulsive colonic contractions by using an implantable device. The objective of this study was to assess the feasibility to induce colonic contractions using a com ...
Planar electrodes are increasingly used in therapeutic neural stimulation techniques such as functional electrical stimulation, epidural spinal cord stimulation and cortical stimulation. Recently, optimized electrode geometries have been shown to increase ...
This dissertation proposes a computational framework targeted at improving the design of currently employed retinal prostheses. The framework was used for analysing factors impacting the performance of prostheses in terms of electrical stimulation for reti ...
These past few years the steady demand from end users has deeply stimulated the research in the field of distributed fibre sensors based on stimulated Brillouin scattering. Some recent progresses are here reported, pushing the limits beyond what has been c ...
Functional electrical stimulation (FES) is limited by the rapid onset of muscle fatigue caused by localized nerve excitation repeatedly activating only a subset of motor units. The purpose of this study was to investigate reducing fatigue by sequentially c ...
We present a finite element based simulation and analysis method to describe the spatial extent of stimulation and the effects of electrode–tissue interactions in subretinal prostheses. In particular, we estimate the threshold stimulation current needed to ...
