Document Summary
The nervous system is plastic - there"s a genetic plan that builds you but environment matters. There are consequences when there is something wrong. The case of genie: because of her environment, her behavior never became normal. Migrate to where they need to go. Functional connections: allow them to interact and communicate with each other. Migration and aggregation (aggregate together to form structure) - (thalamus, basal ganglia) Fertilized egg: totipotent (30hours) - fertilization, 30 hours cleavage, 3 days solid ball. After 3 days, blastocyst: pluripotent (ability to make adult you) - embryonic stem. The inner cell is getting larger and starting to form (6-8 days) After 8 days, becomes baby in a compact disc . Multipotent: unipotent - can make specific cells to do the job( either neuron or liver cells ) At the end of gastrulation, you will have 3 germ layers : ectoderm, mesoderm, Ectoderm: skin, hair, and the nervous system.
