Alterations in brain connectivity due to plasticity and synaptic delay
, 2017 Brain plasticity refers to brain's ability to change neuronal connections, as a result of environmental stimuli, new experiences, or damage. In this work, we study the effects of the synaptic delay on both the coupling strengths and synchronisation in a ...

Synapses: Glia help synapses form and function [PDF]
Current Biology, 1998 AbstractA sophisticated new cell-culture system has shown that glial cells can promote synaptogenesis and enhance the efficacy of synaptic transmission. These effects are not secondary to increased neuronal survival but probably involve changes in neuronal activity levels and a secreted glial factor.

Detachable and Reusable: Reinforced π‐Ion Film for Modular Synaptic Reservoir Computing
Advanced Materials, EarlyView.This study presents a reinforced π‐ion film for organic electrochemical transistors (OECTs), addressing the rapid degradation of organic semiconductor layers. By introducing a mesh support and utilizing a scalable solvent exchange method, the π‐ion film enhances detachability and stability.

Biomimetic Cell Membrane‐Coated Scaffolds for Enhanced Tissue Regeneration
Advanced Materials, EarlyView.This review examines the development and use of cell membrane‐coated scaffolds in tissue engineering. Bioinspired phospholipid and glycocalyx coatings enhance anti‐fouling, anti‐thrombogenic, and selective molecular recognition properties. Native cell membrane coatings further support cell‐specific interactions, immune modulation, and reduced bacterial
