Ithaca, N.Y. is a relatively small college town, but one thing that might make up for its size is its brain power. That’s because Ithaca tops a new list from Lumosity that ranks U.S. cities by their raw cognitive performance.
San Francisco-based Lumosity creates brain-training exercises and has raisedmore than $70 million in funding to date from Discovery Communications, Menlo Ventures, and others. Since it launched back in 2007, Lumosity claims to have amassed the world’s largest dataset of human cognitive performance, with data and insights collected from more than 40 million people.
