Describe the small-world framework. Explain how the framework offers a metaphor for the organization of neurons in the brain. Illustrate your answer with an example drawn from your own social connections or network.
What will be an ideal response?
Ans: Just as the contact of any two random individuals in the world can be accomplished with a limited number of connections, any two nodes in the brain can be represented by only a limited number of connections. Neurons have many short-distance local connections, just as an individual has many friends in their local community. These connections form a hub. Each hub may be connected by a few long-distance connections to another hub, just as an individual’s network of local friends may be connected to a social network in a distant city by the friendships of one or two people. For example, I have many friends in my hometown of Lafayette, LA—my hub. This network is connected to a network in Athens, GA, by my friendship with a woman in that city.
