– Why are specialized functional regions of the brain the same in most people?

Question

The brain has plasticity in what areas perform specific tasks, like when a person has a brain injury in a visual processing region, another section can adapt to take over that function. So why are we born with specific functional regions that are in the same area of the brain for most people? I would expect that the organization would be randomly unique per person.

Answer 1

Two main reasons. First, the structure and development of the brain isn’t random. The baseline structure of the brain is driven by genetics. Second, we are all human beings, and so share a lot genetically and experientially.
