The outermost wrapping of a schwann cell
WebbThe arrow indicates wrapping of an axon by an extended Schwann cell mesaxon. Each Schwann cell-axon family is surrounded by basal lamina and separated from other families by collagen fibrils. Fibroblasts forming flattened layers at the top of the figure are associated with collagen but not basal lamina. WebbThe disclosure provides a biological brain-computer interface comprising genetically modified cells engrafted onto an adult mammal (e.g., mouse) above cortical layer 1, forming an artificial cortical layer termed layer zero (L0). Following engraftment, L0 goes through a developmental process characterized by synchronous waves of activity that …
