Briefly, a poly-l-lysine (PLL)-coated pattern was made on the surface of a square glass chip by microcontact printing (see the areas in in Fig. and the rise in Ca2+, resulting from Ca2+ influxes through calcium-permeable AMPA receptors, voltage-gated Ca2+ channels, and transient receptor potential canonical channels, in axons stimulate the local translation machinery. For comparison,…
