Book excerpt: Medical diagnostic devices are in high demand due to increasing cases of neurodegenerative diseases in the aging population and pandemic outbreaks in our increasingly connected global community. Devices capable of detecting the presence of a disease in its early stages can have dramatic impacts on how it can be treated or eliminated. High cost and limited accessibility to diagnostic tools are the main barriers preventing potential patients from receiving a timely disease diagnosis. This dissertation presents several devices that are aimed at providing higher quality medical diagnostics at a low cost. Brain function is commonly studied with systems detecting the action potentials that are formed when neurons fire. CMOS technology enables extremely high-density electrode arrays to be produced with integrated amplifiers for high-throughput action potential measurement systems while greatly reducing the cost per measurement compared to traditional tools. Recently, CMOS technology has also been used to develop high-throughput electrochemical measurement systems. While action potentials are important, communication between neurons occurs by the flow of neurotransmitters at the synapses, so measurement of action potentials alone is incapable of fully studying neurotransmission. In many neurodegenerative diseases the breakdown in neurotransmission begins well before the disease manifests itself. The development of a dual-mode CMOS device that is capable of simultaneous high-throughput measurement of both action potentials and neurotransmitter flow via an on-chip electrode array is presented in this dissertation. This dual-mode technology is useful to those studying the dynamic decay of the neurotransmission process seen in many neurodegenerative diseases using a low-cost CMOS chip. This dissertation also discusses the development of more traditional diagnostic devices relying on PCR, a method commonly used only in centralized laboratories and not readily available at the point-of-care. These technologies will enable faster, cheaper, more accurate, and more accessible diagnostics to be performed closer to the patient.

This book was released on 2020 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding cognitive processing in intact brains is the subject of intense research efforts that aim to resolve individual and network activity of neuronal cells across different layers of the brain. While efforts to record a large number of individual cellular activity in intact brains are underway, the network-level coordinated activity of neurons result in long-range, low frequency oscillations that carry significant electrophysiological information and is the gold standard for recording neural correlates of cognition from animals and humans. Recently, recording of individual cellular activity, commonly referred to as single units, with high signal-to-noise ratio from the cortical surface was accomplished. Critical to this milestone in electrophysiology was the use of organic microelectrode arrays that (1) possess superior electrochemical junction characteristics enabling them to have contact diameters that are similar to neuronal sizes yet while maintaining low electrochemical impedances and low noise, and (2) enable conformal coverage of thin parylene C device carrier layers to the brain curvature. The small contact diameter, and therefore listening sphere, its low noise, and its intimate contact with the surface of the brain are all attributed as essential conditions to permit the recording of single unit activity from the brain's surface. This thesis appraises the development of novel microelectrode arrays that record single units from the brain's surface, and their application in recording brain activity from anesthetized and awake animal models. The first part of the dissertation discusses the application of Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate, commonly known as PEDOT:PSS--a semiconductive polymer with excellent electrochemical properties--as well as microelectrode contacts that employ large surface area one-dimensional nanostructures, to the electrophysiological investigations in songbird experiments. Significantly, we observed strong correlation of surface-recorded single units with spectrotemporal features of replayed birdsongs across trials and that were also validated with simultaneously implanted depth electrodes. This finding has implications for minimally destructive brain-machine interfaces that can make use of surface-recorded units. Additionally, we carried out systematic investigations to understand the influence of the electrode contact diameter and the contact material on resolving single unit activity from the surface of the brain. Our initial results suggest that contacts with lower impedances result in higher signal amplitude as well as higher biological noise amplitude, due to their sensitivity and that amplitude of single units generally decreases with diameter. While acute recordings can streamline testing of neurotechnologies, chronic recordings are important for applications in which subjects can ultimately engage in behavioral experiments. To this end, the last part of this dissertation concerns with the development and optimization of a chronically stable device form factor. This device leverages the transparency of the parylene C substrate to perform simultaneous electrophysiological recording and multi-photon imaging of neuronal activity in awake mice. We recorded stimulus-evoked calcium indicator responses that correlated with local field potential (LFP) response and higher frequency multi- and single unit activity. This dissertation encompasses advances in the scalable, monolithic fabrication procedure for high-yield PEDOT:PSS microelectrode arrays on parylene C substrates and their utility of electrocorticography (ECoG) recording capability of neuronal activity from intact brains.

This book was released on 2019 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrocorticography (ECoG) arrays are used in clinical mapping for neurosurgical resection and hold the promise for less damaging brain-machine interfaces. Current clinical ECoG electrodes face physical limits to the number of contact sites, spatial resolution (centimeter scale), and contact diameter (millimeter scale), and thus cannot resolve the dynamically changing neural activity over sub-millimeter scales . In addition to these practical limitations, current clinical electrode arrays are constrained to non-conformal electrode-carriers/substrates and to less-optimal metal electrochemical interfaces. Increasing the flexibility of clinical electrodes may lead to higher signal-to-noise ratios as well as higher spatial specificity and this also requires overcoming substantial physical barriers due to the compromised metal electrochemical interface properties. The objectives of this thesis, described in seven chapters, are to develop high performance, safe, and durable neural electrode interfaces to yield stable, high signal-to-noise ratio cortical recordings in animal models as well as in humans. In the second chapter, we demonstrate that sterilization of PEDOT:PSS electrophysiology devices can be performed using an autoclave. We find that autoclaving is a viable sterilization method, leaving morphology unaltered and causing only minor changes in electrical properties. These results pave the way for the widespread utilization of PEDOT:PSS electrophysiology devices in the clinic. In the third chapter, we translate the use of robust PEDOT:PSS microelectrode arrays for safe intraoperative monitoring of the human brain. PEDOT:PSS micro-electrodes measured significant differential neural modulation under various clinically relevant conditions. We report the first evoked (stimulus-locked) cognitive activity with changes in amplitude across pial surface distances as small as 400 [mu]m, potentially enabling basic neurophysiology studies at the scale of neural micro-circuitry. In the fourth and fifth chapters, we present the first systematic study of scaling effects on the electrochemical properties of Pt and Au metallic and PEDOT:PSS organic electrodes from neural recording and stimulation perspectives. PEDOT:PSS coating reduced the impedances of metallic electrodes by up to 18X. The overall reduced noise of the PEDOT:PSS microelectrodes enable a lower noise floor for recording action-potentials with high fidelity. We observed a substantial enhancement in charge injection capacity up to 9.5X for PEDOT:PSS microelectrodes compared to metal ones and 88% lower required power for injecting the same charge density. These results permit quantitative optimization of contact material and diameter for different ECoG applications. In the sixth chapter, We report an effective method of mechanically anchoring the PEDOT within the Au nanorod (Au-nr) structure and demonstrate that it provides enhanced adhesion and overall PEDOT layer stability under various electrochemical (charge injection) and In vivo stability tests. In the seventh chapter, we report the fabrication of pure Pt nanorods (PtNRs) by utilizing low-temperature selective dealloying to develop scalable and biocompatible 1D platinum nanorod (PtNR) arrays that exhibit superb electrochemical properties at various length scales for high-performance neurotechnologies. PtNR arrays record brain activity with cellular resolution from the cortical surfaces in birds, mice, and non-human primates; demonstrating the PtNR microelectrode system as a robust system for high performance and stable neural electrode interfaces.

This book was released on 2012 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: In vitro neurobiological experiments using brain slices have played a key role in improving our understanding of the central nervous system. Microfabricated brain slice chambers and flexible semi-transparent multi-electrode arrays allow controlled local changes in the chemical environments as well as high resolution electrophysiology and optical recording of brain slices which would in turn provide further information of the complex neuronal system. In this study, we exploit the advantages of microfabricated devices, including a microfluidic brain slice chamber for localized chemical stimulation and a flexible microelectrode array for spatial mapping of neuronal activities, to investigate various biophysical properties of cortical spreading depression. First, a microfluidic brain slice chamber is designed and fabricated to permit localized chemical stimulation to specific brain slice cortical regions. We build a numerical finite element model to predict the injected plume shape and the resulting ion distributions in the stimulated brain slice. Various characterization methods, including particle tracking velocimetry, fluorescent imaging and tissue staining, are implemented to verify the fluid dynamics predicted by our model. With the ability to fine control the stimulation area, we vary the stimulation size as well as the extracellular potassium concentration ([K+]e) to study the conditions for the onset of cortical spreading depression. We find a strong correlation between the threshold concentration and the slice area exposed to the increased [K+]e. Our results show that CSD is inducible under the conditions expected in migraine aura. We then explore the use of a flexible microelectrode array to map spatiotemporal electrophysiological activities induced by localized chemical stimulation. We concurrently use the microfluidic device to initiate CSD in mice cortex and the electrode array to record electrical activities accompanying the spreading wave. Besides the consistency between optical and electrical recording, we observe the electrical responses similar to cortical spreading convulsion with a corresponding optical characteristic. In summary, the microfluidic brain slice chamber has been demonstrated with a localized stimulation capability and used to probe the cortical spreading depression initiation and propagation properties. The concurrent use of the microfluidic and microelectrode array techniques has been demonstrated and is shown to be promising in addressing scientific questions. Our work demonstrates a successful implementation of novel microfabricated tools for the neuroscience research.

Available in PDF, EPUB and Kindle. Book excerpt: The brain is a wondrous and complex organ, a biological machine forged by the evolutionary forces of nature. The human brain contains 100 billion neurons and each neuron is connected by synapses to several thousand other neurons. Connected neurons work together to produce perceptions and sensations, memories and emotions, physical movements and abstract constructs. The neurons communicate by means of electricity that passes along and across their cellular membrane. Much of what is known about brain physiology is through the measurement of this electrical activity, either with relatively large electrodes placed on the scalp or tiny microelectrodes inserted into the brain tissue itself. At the finer end of this scale, scientists have discovered much about the way individual neurons extract sensory information, adapt their behavior to form a memory, and convey signals to other regions of the brain. However, it has long been recognized that the brain operates on a global scale, through the collective behavior and interaction of its neural units1. Information is processed in several regions of the brain simultaneously, and the activity of neighboring neurons can be quite different from one another. By one analogy, the attempt to assess brain function by observing a single neuron is like looking at the output of one transistor to learn how a computer works. Thus, the recording of many neurons simultaneously is necessary to truly reveal the mechanisms of the brain2. In recent decades, a variety of recording techniques have been developed for a neural interface such as electroencephalography (EEG), magneto-encephalography (MEG), electrocorticography (ECOG), local field potential (LFP) recordings, micro-electrode array (MEA) and peripheral nerve interfaces (PNIs) to the micron-level precision required for multi-neuron recording. Their small size allows many recording channels to be placed onto one device. One of the goals of neural interface research is to create a seamless connection between the nervous system and the neuroprostheses either by stimulating or by recording from neural tissue to restore or substitute function for individuals with neurological deficits or disabilities. Hence, significant amount of scientific and technological efforts have been devoted to develop neural interfaces that link the nervous system with robotic prosthetic devices. The creation of a novel neural interface is essential for developing the full potential of advanced prosthesis technology required to replace lost limbs. Additionally, meticulous studies of a single neuron and between neurons utilizing the neural interface technology should be made to elucidate fundamental biological phenomena such as cellular processes and heterogeneities. Particularly, an electrophysiological study of neural networks can provide knowledge to unravel the functions of brain. When fundamental research about molecular and cellular mechanisms of a single neuron and electrophysiological studies using neural interfaces on both the central and peripheral nervous systems are done together, it has a synergistic effect on neural interface technology. The research and methodologies described in this dissertation stem from our research group's efforts to optimize the design and expand the applications of neural interfaces. The dissertation is organized into four chapters. Chapter 1 is a review of neural interface technology and study of neural signal detection. This chapter provides a foundation for Chapter 2 and 3. Chapter 2 is a study of a neural interface as cellular level research. We present an advanced single-neuronal cell culture and monitoring platform using a fully transparent microfluidic dielectrophoresis (DEP) device for unabated monitoring of neuronal cell development and function. The device is mounted inside a sealed incubation chamber to ensure improved homeostatic conditions and reduced contamination risk. Consequently, we successfully trap and culture single neurons on a desired location and monitor their growth process over a week. Chapter 3 deals with the specific application of PNIs to the sciatic nerve of a rat as a nervous system-level research. We developed novel devices, "cuff and sieve electrodes" (CASE), that integrate microfabricated cuff and sieve electrodes capable of broad (via cuff) and precise (via sieve) selectivity to increase the strengths and simultaneously decrease the weaknesses of traditional electrode designs. We performed terminal device implantations in a rat sciatic transection and repair model to test the capacity of the CASE interface. The sciatic nerve was stimulated by the sieve portion of the CASE electrode and somatosensory evoked potentials were recorded from the somatosensory cortex via micro-eletrocorticography. The ability to elicit cortical responses from sciatic nerve stimulation demonstrates the proof of concept for both the implantation and chronic monitoring of CASE interfaces for innovative prosthetic control. Lastly, in Chapter 4, I will identify areas in which further investigation is needed and propose future directions of both cellular and system-level neural interface.

This book was released on 2021 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neuromodulation devices are increasingly used in interrogating and treating neurological dysfunction in the human brain, spinal cord, and peripheral nerves. Recently, there has been an explosion of interest in applying these devices for brain-machine interfaces and advancing the state-of-the-art interface with the human brain. Toward this end, the Utah array has been the powerhouse of the BrainGate project that partially restored motor and sensory function to patients with neurological injury, though the array itself has advanced little in the last three decades. In this work, we leverage advanced dual-side lithographic microfabrication processes to demonstrate a 1024 channel penetrating Si microneedle array (SiMNA) that is scalable in its recording capabilities and cortical coverage. The SiMNA is built on flexible and transparent substrates permitting simultaneous optical and electrophysiological interrogation of the brain activity and is compliant to brain movements. We use the SiMNA to demonstrate reliable recordings of spontaneous and of evoked field potentials and of single unit activities in chronically implanted mice for up to 196 days in response to optogenetic and to whisker air-puff stimuli. Significantly, the 1024 channel SiMNA established detailed spatiotemporal mapping of broadband brain activity in rats. This novel scalable and biocompatible SiMNA with its multi-modal capability and sensitivity to broadband brain activity will accelerate our progress in fundamental neurophysiological investigations and establishes a new milestone for penetrating and large area coverage microelectrode arrays for brain-machine interfaces.The reach of soft substrates extends well beyond the curvilinear and pulsating brain toward spinal cord that relays the information bidirectionally to the brain and that has its own processing circuits for fundamental locomotion tasks. Materials that comprise of superior contact properties for recording and stimulation, that are minimally-invasive, and that are biocompatible and flexible have profound impact on the way we record and stimulate activity of the spinal cord. One important application of such devices is to aid in restoring function in spinal cord injury (SCI). However, thresholds for motor recruitment and for tissue damage during direct current stimulation in the spinal cord using recent microelectrode technologies are not yet established. Additionally, stimulation on the ventral side of the spinal cord in a closer proximity to the motor fibers is advantageous but systematic studies on the efficacy of microelectrode arrays for ventral stimulation versus dorsal stimulation and the stimulation parameters needed for initiation of motor response have not been studied before. This work reports the initiation thresholds for motor recruitment of rodent hindlimb from dorsal and ventral stimulation with various electrode sizes using a newly developed microelectrode material in our laboratory, the platinum nanorod (PtNR) contacts using two device configurations. Device type 1 comprises of microelectrodes of 9 diameters (40/60/80/100/120/140/160/180/200 [mu]m) and a macroelectrode of 250 [mu]m in diameter on sub-10 [mu]m thin flexible parylene-C substrate. Using Device type 1 in the acute setting for dorsal or ventral-lateral spinal cord implantation and electrical stimulation in rats, we quantified lower current thresholds and charge densities, and a lower critical diameter for evoking responses in the sciatic nerves and electromyography responses in hindlimb muscles. Device type 2 consists of three representative diameters (40/100/200 [mu]m) of PtNR electrodes from Device type 1 on sub-10 [mu]m thin flexible polyimide substrate for investigating the stability of the platform on semi-chronic rat implants accompanied by a rigorous stimulation paradigm with a total of over 1 million pulse pairs. This stimulation paradigm is designed based on the a 7-hour stimulation session initially implemented by McCreery et al. In our work, we used a much higher pulse frequency of ~ 200 Hz over the duration of 84 minutes doubling the amount of charge used in McCreery et al.'s work. Device type 3 consists of 128 channels (4 × 32 array) of PtNR electrodes with 30 [mu]m diameter on sub-10 [mu]m thin flexible parylene-C substrate which was used to detect spatiotemporal compound action potentials (CAP) from an acute pig model and demonstrate the high scalability of the device platform.

Available in PDF, EPUB and Kindle. Book excerpt: Neural electrodes enable the recording and stimulation of bioelectrical activity in the nervous system. This technology provides neuroscientists with the means to probe the functionality of neural circuitry in both health and disease. In addition, neural electrodes can deliver therapeutic stimulation for the relief of debilitating symptoms associated with neurological disorders such as Parkinson's disease and may serve as the basis for the restoration of sensory perception through peripheral nerve and brain regions after disease or injury. Lastly, microscale neural electrodes recording signals associated with volitional movement in paralyzed individuals can be decoded for controlling external devices and prosthetic limbs or driving the stimulation of paralyzed muscles for functional movements. In spite of the promise of neural electrodes for a range of applications, chronic performance remains a goal for long-term basic science studies, as well as clinical applications. New perspectives and opportunities from fields including tissue biomechanics, materials science, and biological mechanisms of inflammation and neurodegeneration are critical to advances in neural electrode technology. This Special Issue will address the state-of-the-art knowledge and emerging opportunities for the development and demonstration of advanced neural electrodes.

Cochlear prostheses [1] are one example of sensory prostheses that are already used in patients. Retinal prostheses are currently under research [2]. Recent neurophysiological experiments [3, 4] show that brain signals recorded from motor cortex carry information regarding the movement of subject’s limbs (Fig. 1.1). These signals can be further used to control ext- nal machines [4] that will replace missing limbs, opening the ?eld of motor prosthetics, devices that will restore lost limbs or limb control.
