Tai’s 14 now. As he goes through adolescence, there are all sorts of weird things happening in his brain that are literally reshaping it, getting him ready for adulthood!

This week Tai spoke to:

• Frances Jensen, Chair of Neurology in the Perelman School of Medicine at the University of Pennsylvania

• Juliet Davidow, psychology professor who developed the Learning and Brain Development Lab at Northeastern University
