Generically engineered to over-express the NR2B gene, Hobbie-J consistently out-performed the normal Long Evans rat at complex tasks. A similarly engineered mouse, Doogie, showed memory improvement a decade earlier.

book, the transgenic rat was able to remember novel objects, such as a toy she played with, three times longer than the average Long Evans female rat, which is considered the smartest rat strain. Hobbie-J was much better at more complex tasks as well, such as remembering which path she last traveled to find a chocolate treat.
