Unformatted text preview: 2-2-10 Brain Development, Plasticity & Repair president@uh.edu Development of the Brain A. Neural plate thickens B. Neural tube forms - "neurulation" I. Anterior end becomes brain II. Posterior end becomes spinal cord III. Fluid inside becomes ventricles & central canal failure of the neural tube to close properly results in a neural tube defect. a. Anencephaly rostral neural tube doesn't close (the brain does not develop) b. Spina bifida caudal neural tube doesn't close C. Growth & Development of Neurons I. Proliferation II. Migration III. Differentiation IV. Myelination V. Synaptogenesis D. Survival of Neurons I. Neurotrophins II. Apoptosis E. Formation of Neural Circuitry I. Axonal pathfinding Neuroplasticity A. Some mechanisms of neuroplasticity include: I. Dendritic branching II. Cortical reorganization III. Neurogenesis occurs in the lateral of the ventricles and the hippocampus Q: What do Development & Repair Have in Common? A: Plasticity!! expression of neurotrophic factors formation of new connections generation of new cells cortical reorganization ...
