Abstract:
Intraspinal microstimulation (ISMS) is an emerging method that is applied to neuroprosthesis aimed at individuals with spinal cord injury. Compared to traditional spinal stimulation or peripheral nerve stimulation methods, ISMS can activate muscle groups in organised synergies and thus can provide finer control of the generated force with reduced muscle fatigue. As the spinal cord is the neural link between the central and peripheral nervous systems, it is convenient to use this in accessing neurons associated with limb movement within a small area. For example, the relevant length of the spinal cord controlling the lower limbs in humans is only 5 cm. However, this means that any implant surgery is limited to some extent, on the other hand, this means ISMS needs to use invasive electric neural stimulation (ENS) with microelectrodes to access the target motor neurons to achieve a higher spatial resolution. Similar to other implantable ENS systems, an ISMS system needs to be compact, safe and energy efficient (in addition to effectively provide the required therapy). Although existing implantable neural stimulators fulfil these basic requirements, there is still much room for improvement. Depending on whether the stimulus is current or voltage controlled, the stimulator can be good for either safety and controllability or energy efficiency. Since the trend in the semiconductor industry is to reduce power consumption in integrated circuits, a current controlled stimulator is usually preferable by experimental neuroscientists. However, there is a new trend to combine these two control modalities, to enjoy the benefits of both. Following this trend, this thesis starts by focusing on a third modality -- charge controlled stimulation, which delivers the stimulus in charge packets. This eliminates the voltage headroom required for relatively high output resistances in current controlled stimulators whilst preserving the controllability over the total charge delivered. Charge controlled stimulation is thus proposed for having the potential to be as energy efficient as voltage controlled stimulation and as safe as current controlled stimulator. A novel circuit for charge mode stimulation is described based on a charge metering approach that has been adopted from nuclear engineering. Experimental results demonstrate the feasibility of this approach and also identify the key challenges. This is then extended to a novel reconfigurable, multi-modal and multichannel stimulator circuit. This is the first integrated system to implement current, voltage and charge control stimulation within a reconfigurable channel architecture. This has been developed to investigate the effect of dynamic multipolar electrode reconfiguration with the aim of focusing or steering the stimulus. To this end, different stimulus delivery methods can be tested for multipolar spatial control. The concept of multipolar stimulation is then investigated from a theoretical standpoint. The ability to apply this in improving the spatial resolution in ISMS can be achieved by confining the stimulus spread (thus reducing destructive crosstalk). This method can also be used to shift the stimulus voltage field away from the delivering electrode so as to correct implant placement error during surgery. A theoretical computational model is developed to investigate the effect of dynamic multipolar electrode reconfiguration with the aim of focusing or steering the stimulus. It is intended, together with the developed multichannel stimulator, that this will be used in future to develop advanced multipolar strategies that can achieve spatial hyperacuity for ISMS, and more generally in ENS.

Abstract:
Spinal cord injury (SCI) is a devastating condition affecting the quality of life of many otherwise healthy patients. To date, no cure or therapy is known to restore functional movements of the arm and hand, and despite considerable effort, stem cell based therapies have not been proven effective. As an alternative, nerves or muscles below the injury could be stimulated electrically. While there have been successful demonstrations of restoration of functional movement using muscle stimulation both in humans and non-human primates, intraspinal microstimulation (ISMS) could bear benefits over peripheral stimulation. An extensive body of research on spinal stimulation has been accumulated – however, almost exclusively in non-primate species. Importantly, the primate motor system has evolved to be quite different from the frog's or the cat's – two commonly studied species –, reflecting and enabling changes in how primates use their hands. Because of these functional and anatomical differences, it is fair to assume that also spinal cord stimulation will have different effects in primates. This question – what are the movements elicited by ISMS in the macaque – will be addressed in chapters 2 and 3. Chronic intraspinal electrode implants so far have been difficult to realise. In chapter 4 we describe a novel use of floating microelectrode arrays (FMAs) as chronic implants in the spinal cord. Compared to implanted microwires or other arrays, these FMAs have the benefit of a high electrode density combined with different lengths of electrodes. We were able to maintain these arrays in the cord for months and could elicit movements at low thresholds throughout. If we could build a neural prosthesis stimulating the spinal cord, how would it be controlled? Remarkable progress has been recently achieved in the field of brain-machine interfaces (BMIs), for example enabling patients to control robotic arms with neural signals recorded from chronically implanted electrodes. Chapter 5 of this thesis examines an approach that combines ISMS with cortical control in a macaque model for upper limb paralysis for the first time and shows that there is a behavioural improvement. We have devised an experiment in which a monkey trained to perform a grasp-and-pull task receives a temporary cortically induced paralysis of the hand reducing task performance. At the same time, cortical recordings from a different area allow us to control ISMS at sites evoking hand movements – thus partially restoring function. Finally, in appendix A we describe a system we developed in order to introduce automated positive reinforcement training (aPRT) both at the breeding facility and in our animal houses. This system potentially reduces time spent on training animals, adds enrichment to the monkeys' home environment, and allows for suitability screening of monkeys for behavioural neuroscience experiments.

Abstract:
Undulatory locomotion is a common and powerful strategy used in nature at different biological scales by a broad range of living organisms, from flagellated bacteria to prehistoric snakes, which have overcome the complexity of living in ”flowable” media. By taking inspiration from this evolution-induced strategy, we aim at modelling the locomotion in a granular and viscous environment with the objective to provide more insights for designing robots for soil-like media exploration. Moreover, in contrast to common types of movement, the granular locomotion is still not well understood and is an open and challenging field. We approached this phenomenon with several tools: (i.) numerically, via coupling the Finite Element Method (FEM) with the Discrete Element Method (DEM) using ABAQUS; (ii.) analytically, by employing the Lagrangian formalism to derive the equations of motion of a discrete and continuous system subject to non-conservative forces, and (iii.) experimentally, by creating an ad-hoc set up in order to observe the migration of microfibres used for the treatment of spinal cord injuries. The computational attempts to model the motion in a granular medium involved the simulation of the dynamics of an elastic beam (FEM) surrounded by rigid spherical particles (DEM). A propulsion mechanism was introduced by sinusoidally forcing the beam’s tip normally to the longitudinal axis, while the performance of the locomotion was evaluated by means of a parametric study. Depending on the parameters of the external excitation, after a transient phase, the slender body reached a steady-state with a constant translational velocity. In order to gain physical insights, we studied a simplified version of the previous continuous beam by introducing a discrete multi-bar system. The dynamics of the latter was analytically derived, by taking into account the forces exchanged between the locomotor and the environment, according to the Resistive Force Theory. By numerically solving the equations of motion and evaluating the input energy and dissipations, we were able to define the efficiency and thus provide an effective tool to optimise the locomotion. It is worth mentioning that the two approaches, despite the different physical hypothesis, show a qualitatively and quantitatively good accordance. The numerical and analytical models previously analysed have shown promising results for the interpretation of "ad-hoc" experiments that demonstrate the migration of a microfibre embedded in a spinal cord-like matrix. This migration needs to be avoided, once the regenerative microfibre is implanted in the lesioned spinal cord, for the sake of the patients health.

Abstract:
Intraspinal microstimulation (ISMS) is a novel electrical stimulation approach to restore standing and ambulation in people with spinal cord injury. The technique entails inserting an array of microwires into the lumbosacral enlargement of the spinal cord to activate neuronal networks that control locomotion. Additionally, ISMS can be utilized to investigate the organization of these networks. In the present study, experimental methodology was developed to map the distribution of ISMS-activated neurons using immunohistochemistry to label c-Fos, an activity-dependent marker. The influence on c-Fos expression of the following conditions was studied: decerebration, laminectomy, microwire implantation, and ISMS. Data revealed that microwire implantation and decerebration minimally influenced c-Fos, while a laminectomy substantially increased c-Fos expression. Furthermore, results indicated that it is vital to monitor stimulation and adjust stimulus amplitude throughout the duration of stimulation. Using these data, a protocol was established that would aid in mapping the ISMS activated neuronal networks.
