In 2014, the case of a 24-year-old woman who had just discovered she was born without a cerebellum made headlines around the world. The details of this case were combined with other published cases of cerebellar agenesis to create an active learning exercise for an undergraduate developmental and systems neuroscience course. By reading an intriguing narrative and answering questions in stages, students work together to apply and extend their knowledge of brain development and cerebellar function. The case can be used to introduce new information in a "flipped classroom" setting or as an interactive exam review.
