I'm not sure how else to phrase this. I'm curious as to what happens when someone makes new connections. Does anything change in the person's "mind"? Are there any physical changes to the brain? New wrinkles to the brain's surface?
Another way of explaining it is when someone finds a new pathway that they then explore. I guess a simpler analogy is humor; what happens to the brain when someone finds similarities between two apparently dissimilar things?
Hopefully I've explained my question well enough. If anyone needs me to elaborate further, just let me know!
