Document Summary
Lecture 2 development of neural bases of social cognition networks, Neural development (neurodevelopment): begin as single fertilized egg and end with functional adult brain. House analogy: nick finds a picture of a dream house in a magazine. He decides to build this house himself (due to the economy). This house has all the essential machines that are required to run a house. On the main floor it will have kitchen, family room etc. The top floor will have bedrooms and washroom etc. He realizes that the house won"t materialize by itself. So he: gets blueprints, foundation and laying concrete, scaffolding of the house, needs to do wiring but the blueprints don"t tell you where to put the wires, or the path the wires have to take. Similarly, the way we perceive the developing brain is similar to the house analogy.
