Processes of Neural Development Induction: Process allowing ectoderm to transform into neural plate Proliferation: Cell division process that creates the billions of cells of the brain Migration: Movement of newly formed cells to their final destination within the brain Aggregation: Grouping of similar cells as 1st step in forming functional brain areas Differentiation: Process by which cells acquire their unique properties. Circuit formation: Formation of synaptic connections Apoptosis: Programmed cell death. Elimination of unwanted cells and connections.
