  7. Methods to induce polarity in constructed neuronal networks

    This work focused on the control of neuronal polarity in geometrical patterned neuronal networks. Two different approaches were taken in order to direct polarity within a neuronal network. The first strategy was to chemically pattern two proteins with distinct effects on neurite growth. Aligned …
