Stephanie Prince explains her research with a scenario many Atlantans can relate to.
Imagine you're driving to the Atlanta airport to pick up a friend. They call to say they're in the terminal - but they're not sure which one. North, maybe? You head that direction through the maze of roads around the airport.
Then they call back. They're actually in the South Terminal. So you make a quick mental adjustment and switch your route to arrive at the correct side of the airport.
You had a plan. You received new information. You quickly changed your destination.
The question Prince has studied is this: How does that process happen in the brain?
A new research paper in Nature Communications is offering insights into that decision-making. And it could help scientists as they work to better understand when brain disorders such as Parkinson's and Alzheimer's impair those processes.
