Dear colleagues, We would like to draw your attention to a series of recent papers dedicated to models of structural plasticity. Developing as well as mature brains are much less hard-wired than traditionally thought. Formation of new connections and breaking of existing connections (structural plasticity) by dendritic spine and axonal bouton turnover, as well as re-routing of axonal branches, can cause a dramatic rewiring of brain connectivity, which so far has largely been disregarded in neuronal network models. The following papers describe novel models of structural plasticity: Homeostatic structural plasticity increases the efficiency of small-world networks Markus Butz, Ines D.
