Striola, also known as "sulcus limitans," is a groove located in the brainstem. This groove helps separate the ventral and dorsal regions of the brainstem. Synonyms for striola include the "limiting sulcus," the "sulcus limitans" and the "transverse groove." Additionally, the term "sulcus medialis" can also be used to describe a similar structure within the brainstem. These synonyms are important for neuroanatomists and medical professionals to understand in order to correctly identify and describe different structures within the brain, allowing for proper diagnosis and treatment of neurological conditions.
