Antioxidative and Conductive Nanoparticles-Embedded Cell Niche for Neural Differentiation and Spinal Cord Injury Repair

Chengheng Wu et al.

Summary: This study developed difunctional polypyrrole nanoparticles incorporated into bioactive collagen/hyaluronan hydrogel to construct an antioxidative and conductive microenvironment for nerve regeneration. The embedded PPy protected BMSCs from oxidative damage and promoted neuronal differentiation with the synergy between conductivity and electrical stimulation, associated with PI3K/Akt and MAPK pathway. In SCI rats, the difunctional hydrogel laden with BMSCs restored bioelectric signal transmission, inhibited secondary damage, and facilitated neurogenesis, resulting in prominent nerve regeneration and functional recovery.

Electrode pooling can boost the yield of extracellular recordings with switchable silicon probes

Kyu Hyun Lee et al.

Summary: State-of-the-art silicon probes for electrical recording from neurons have thousands of recording sites, but typically have fewer wires carrying signals off the probe, limiting the number of channels that can be recorded simultaneously. The authors propose electrode pooling, using a single wire to serve multiple channels through controllable switches, as a solution to this limitation.
