How do different brain regions/structures produce different experiences?

Description : How do different brain regions/structures produce different experiences?

Last Answer : Not a brain expert, but since it’s known that a brain damaged person can train his brain “re-learn” lost abilities—like when a stroke victim recovers the ability to speak or control limbs—then I don’t think it’s necessarily due to structural differences of those regions.
