The spatial and temporal control of alternative splicing is a major mechanism used to generate proteomic diversity in the brain. Microarray and Next Generation Sequencing approaches reveal mechanistic insights about networks of tissue-specific RNA binding proteins and micro RNAs that coordinate suites of alternative splicing patterns during neuronal differentiation. In the context of large-scale changes, one alternative splicing switch during embryonic brain development is crucial for neuronal migration and the laminar organization of the cerebral cortex. A major challenge to understand alternative splicing at the systems level is now being approached by the design of integrative modeling approaches that predict the combinatorial control of brain-specific exons.
