Cognitive neuroscientist Nick Turk-Browne helps an infant into an fMRI machine.

What infant fMRI is revealing about the developing mind

Cognitive neuroscientists have finally clocked how to perform task-based functional MRI experiments in awake babies—long known for their inability to lie still or take direction. Next, they aim to watch cognition take shape and settle a debate about our earliest memories—with one group publishing a big clue today.
