We are constantly fascinated by the brain and how it shapes behavior. Our chats about what is going on in our kids’ heads led to our last posts about the boy, girl, and even ADHD brain. So naturally as moms to twins, we turned our attention to twin neurobiology.
Twin brains seem to operate in a world of their own. It’s almost like one brain expressed through two distinct personalities. For example, my daughter H leans into logic and reasoning, while K brings emotional depth and creativity. Together as identical twins, they feel like complementary halves of a shared whole. My husband and I have also seen moments that defy explanation: one twin tearing up when the other gets hurt, or both making the same gesture at the exact same time. It’s weird, but it’s pretty cool.
Patti having fraternal twins, their brains are less complementary but more like synergistic sound boards. As they learn, they take cues from each other, speeding up their understanding and sometimes their competitiveness.
It naturally leads to the question: Are twin brains wired differently than singleton ones?
In some ways, yes. In others, not quite.
