How does the motor cortex enable mammals to generate accurate, complex, and purposeful movements? A cubic milimeter of motor cortex contains roughly ̃10̂5 cells, an amazing ̃4 Km of axons and ̃0.4 Km of dendrites, somehow wired together with ̃10̂9 synapses. Corticospinal neurons (a.k.a. Betz cells, upper motor neurons) are a key cell type, monosynaptically conveying the output of the cortical circuit to the spinal cord circuits and lower motor neurons. But corticospinal neurons are greatly outnumbered by all the other kinds of neurons in motor cortex, which presumably also contribute crucially to the computational operations carried out for planning, executing, and guiding actions. Determining the wiring patterns, the dynamics of signalling, and how these relate to movement at the level of specific excitatory and inhibitory cell types is critically important for a mechanistic understanding of the input-output organization of motor cortex. While there is a predictive microcircuit hypothesis that relates motor learning to the operation of the cerebellar cortex, we lack such a microcircuit understanding in motor cortex and we consider microcircuits as a central research topic in the field. This Research Topic covers any issues relating to the microcircuit-level analysis of motor cortex. Contributions are welcomed from neuroscientists at all levels of investigation, from in vivo physiology and imaging in humans and monkeys, to rodent models, in vitro anatomy, electrophysiology, electroanatomy, cellular imaging, molecular biology, disease models, computational modelling, and more.

Microelectrode arrays are increasingly used in a wide variety of situations in the medical device sector. For example, one major challenge in microfluidic devices is the manipulation of fluids and droplets effectively at such scales. Due to the laminar flow regime (i.e., low Reynolds number) in microfluidic devices, the mixing of species is also difficult, and unless an active mixing strategy is employed, passive diffusion is the only mechanism that causes the fluid to mix. For many applications, diffusion is considered too slow, and thus many active pumping and mixing strategies have been employed using electrokinetic methods, which utilize a variety of simple and complex microelectrode array structures. Microelectrodes have also been implemented in in vitro intracellular delivery platforms to conduct cell electroporation on chip, where a highly localized electric field on the scale of a single cell is generated to enhance the uptake of extracellular material. In addition, microelectrode arrays are utilized in different microfluidic biosensing modalities, where a higher sensitivity, selectivity, and limit-of-detection are desired. Carbon nanotube microelectrode arrays are used for DNA detection, multi-electrode array chips are used for drug discovery, and there has been an explosion of research into brain–machine interfaces, fueled by microfabricated electrode arrays, both planar and three-dimensional. The advantages associated with microelectrode arrays include small size, the ability to manufacture repeatedly and reliably tens to thousands of micro-electrodes on both rigid and flexible substrates, and their utility for both in vitro and in vivo applications. To realize their full potential, there is a need to develop and integrate microelectrode arrays to form useful medical device systems. As the field of microelectrode array research is wide, and touches many application areas, it is often difficult to locate a single source of relevant information. This Special Issue seeks to showcase research papers, short communications, and review articles, that focus on the application of microelectrode arrays in the medical device sector. Particular interest will be paid to innovative application areas that can improve existing medical devices, such as for neuromodulation and real world lab-on-a-chip applications.

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.
