Glial cells are known to actively participate in neuronal development by shaping neuronal connections through axon pruning and by controlling dendritic spine morphology. These functions may in part be mediated by engulfment of neuronal structures and trans-endocytosis of neuronal material into glial cells. These processes are not well understood, and the(More)
The effect of boundaries on pattern formation was studied for the catalytic oxidation of carbon monoxide on platinum surfaces. Photolithography was used to create microscopic reacting domains on polycrystalline foils and single-crystal platinum (110) surfaces with inert titanium overlayers. Certain domain geometries give rise to patterns that have not been(More)
