Silicon Nanowire Mats Enable Advanced Bioelectrical Recordings in Primary DRG Cell Cultures
Advanced Healthcare Materials, EarlyView.SiNW mat‐based MEA (NW_MEA) enables continuous intracellular recordings from neurons in primary rat DRG cell cultures, identifying C‐fiber nociceptors. Supported by an astrocyte feeder layer, SiNW mat promotes DRG neuron and glial cell growth, preserving in vivo‐like cell characteristics and allowing drug‐modulated activity monitoring.

Dipolar extracellular potentials generated by axonal projections
eLife, 2017 Extracellular field potentials (EFPs) are an important source of information in neuroscience, but their physiological basis is in many cases still a matter of debate.

Proceedings of the National Academy of SciencesAlready in the late 19th / early 20th century, neuroscientists such as Wilhelm His, Ross Granville Harrison, and Paul Weiss, discussed the role of mechanical signals in neuronal development (1-4). A few decades later, in two seminal papers, Dennis Bray showed that extending neuronal processes (‘neurites’) are under tension, and that the external ...

Advanced Healthcare Materials, EarlyView.Through tuning biomimetic scaffold stiffness and matrix composition the reparative capacity of astrocyte progenitors is enhanced. Soft, collagen‐IV/fibronectin‐functionalized scaffolds promote progenitor growth while improving angiogenic, immunomodulatory, and neurotrophic capacity in a stiffness and matrix‐dependent manner, demonstrating the impact of

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

Advanced Materials, EarlyView.A novel one‐shot integration electropolymerization (OSIEP) method is developed as a breakthrough on the intricate photolithographic steps, enabling to compress all processes from synthesis to channel integration in one‐shot manufacturing. The specially designed dual bipolar electrodes provide the targeted depositions of poly(3,4‐ethylenedioxythiophene)

Topologically Restricted Appearance in the Developing Chick Retinotectal System of Bravo, a Neural Surface Protein: Experimental Modulation by Environmental Cues [PDF]
, 1990 A novel neural surface protein, Bravo, shows a pattern of topological restriction in the embryonic chick retinotectal system. Bravo is present on the developing optic fibers in the retina; however, retinal axons in the tectum do not display Bravo.

Optoelectronic Devices for In‐Sensor Computing
Advanced Materials, EarlyView.The raw data obtained directly from sensors in the noisy analogue domain is often unstructured, which lacks a predefined format or organization and does not conform to a specific data model. Optoelectronic devices for in‐sensor visual processing can integrate perception, memory, and processing functions in the same physical units, which can compress ...
