Neural Regeneration Research, 2015 The extracellular matrix (ECM) performs essential functions in the differentiation, maintenance and remodeling of tissues during development and regeneration, and it undergoes dynamic changes during remodeling concomitant to alterations in the cell-ECM ...

A Novel Approach to Implementing Artificial Thalamic Neurons with Ferroelectric Transistors
Advanced Functional Materials, EarlyView.Artificial neurons created using CMOS technology often require a large number of transistors and capacitors. This study introduces an artificial thalamic neuron that employs only five CMOS compatible ferroelectric transistors. The manufactured thalamic neuron demonstrates leaky integrate‐and‐fire‐or‐burst (LIFB) functionalities, featuring self ...

Sialic acid accelerates the electrophoretic velocity of injured dorsal root ganglion neurons
Neural Regeneration Research, 2015 Peripheral nerve injury has been shown to result in ectopic spontaneous discharges on soma and injured sites of sensory neurons, thereby inducing neuropathic pain.

Microchannels as Axonal Amplifiers
IEEE Transactions on Biomedical Engineering, 2008 An implantable neural interface capable of reliable long-term high-resolution recording from peripheral nerves has yet to be developed. Device design is challenging because extracellular axonal signals are very small, decay rapidly with distance from the axon, and in myelinated fibres are concentrated close to nodes of Ranvier, which are around 1 mum ...

Advanced Healthcare Materials, EarlyView.In this study, a cuff‐free, less‐invasive surgical approach for vagus nerve stimulation (VNS) by combining ultrathin Y‐shaped kirigami electrodes is developed with a chemically cross‐linked hydrogel adhesive (hydrogel‐kirigami). Unlike conventional cuff implantation, which may damage nerves and nearby critical vessels, this new technique minimizes ...

Measurement of current‐voltage relations in the membrane of the giant axon of Loligo
Journal of Physiology, 1952 The importance of ionic movements in excitable tissues has been emphasized by a number of recent experiments. On the one hand, there is the finding that the nervous impulse is associated with an inflow of sodium and an outflow of potassiuim (e.g ...

Engineering the Future of Restorative Clinical Peripheral Nerve Surgery
Advanced Healthcare Materials, EarlyView.What if damaged nerves could regenerate more effectively? This review unveils cutting‐edge strategies to restore nerve function, from biomaterial scaffolds and bioactive molecules to living engineered tissues. By accelerating axonal regrowth, preserving Schwann cells, and enhancing connectivity, these approaches are reshaping nerve repair—offering new ...

Intra-axonal Synthesis of SNAP25 Is Required for the Formation of Presynaptic Terminals
Cell Reports, 2017 Localized protein synthesis is a mechanism for developing axons to react acutely and in a spatially restricted manner to extracellular signals. As such, it is important for many aspects of axonal development, but its role in the formation of presynapses ...

Time-dependent diffusion in undulating structures: Impact on axon diameter estimation [PDF]
arXiv, 2019 Diffusion MRI may enable non-invasive mapping of axonal microstructure. Most approaches infer axon diameters from effects of time-dependent diffusion on the diffusion-weighted MR signal by modelling axons as straight cylinders. Axons do not, however, run in straight trajectories and so far, the impact of the axonal trajectory on diameter estimation has
