They discussed the brain, its neural net structures, and what happens when some portion is diseased, particularly how brain functions can sometimes recover by sidestepping a dysfunctional region. “Well, gee, you know,” Baran remembered thinking, “the brain seems to have some of the properties that one would need for real stability.” It struck him as significant that brain functions didn’t rely on a single, unique, dedicated set of cells. This is why damaged cells can be bypassed as neural nets re-create themselves over new pathways in the brain.
