Review 1. During differentiation the new neurons identity is defined, How? What are the two mechanisms? Cell autonomus and Induction (peer pressure) 1. What advantage does induction provide the developing CNS compared to cell autonomus development? Adaptability 1. The process of synaptogenesis occurs in a random fashion (T or F). 1. False 2. How does the axon make the right synapses? Growth cone, chemoattractants, slit
