Test your knowledge on the stages of brain development in a fetus, including neurulation, proliferation, migration, differentiation, axon growth, synaptogenesis, apoptosis, and myelination. Learn about the early formation of cell precursors, neural plate invagination, and neural fold fusion during neurulation.
