Document Summary
Test intelligence by giving a not abstract question and receive a definite answer from child. Zygote divides to form nerve and brain cells. Themes of the video: how do neurons find their place, know where to go , and what functions it serve, are all connections equally important, to what extent does plasticity contribute to the development of brain region. Is the function of a region permanent or changeable. Each nerve cell forms 1 to 10 000 connection. Nervous system is in an organized, non-random manner. Unlike skin cells, neurons cannot be replaced and do not replicate itself. Grow in neural tube, layer after layer like an onion. Hold on to guard cell with its nucleus at the back during migration from brain to body location. Evidence to support that young neuron has an idea of its migration. The migration destination is determined from neighbouring cell.
