The manuscript by Stefanatos, Gershkoff, and Madigan is the inaugural contribution to the new Neurobehavioral Grand Rounds feature of JINS. Case reports have been published in JINS in the past, but the goal of this new feature is to highlight the importance of case reports that are theoretically driven and have the potential to influence future research in the area. You will see that this case fits that description very well. In order to emphasize the larger context of the case, for each Grand Rounds an expert in the area will be asked to provide a short introduction. Dr. Jeffrey Binder, a neurologist at the Medical College of Wisconsin and an expert in the neural basis of language, has written an introduction that emphasizes the value of this case in terms of its utilization of a careful perceptual analysis combined with anatomical data to better characterize this classic syndrome.
