Handmade anatomy models may be a complementary useful tool to dissection and prosection, since the student interacts with the body structure in a three-dimensional way. In this study homemade dough (biscuit) was used to create a brain model. Two anatomy trainees from the medical school of the Universidade Federal Fluminense (Niteroi Brazil) were challenged to model the gross anatomy of the lateral aspect of the brain. They prepared and handled homemade dough to produce a simple and low cost model of the cerebral hemisphere. Styrofoam balls fixed by pins were used to create a framework, and dough rolls were modeled in order to create the brain sulci and gyri.At the end, the model closely resembled three-dimensional features of the human brain. Also, brain lobes were easily identified, as well as some major gyri and sulci, such as the central and lateral sulci and the precentral and postcentral gyri. In conclusion, the three-dimensional spatial characteristics, the clear identification of sulci and gyri and the brain lobes, make this model a good tool for students who only require basic anatomy in their curriculum.

KEY WORDS: Simple anatomy models; Brain; Neuroanatomy.
