The Sylvian fissure, also known as the lateral or Sylvian sulcus, is a prominent landmark in the human brain that separates the frontal and parietal lobes from the temporal lobe. Other terms that can be used to describe this feature include the lateral cerebral sulcus, lateral fissure, sulcus lateralis cerebri, and lateral sulcus of the brain. The Sylvian fissure is named after François Sylvius, a 17th-century Dutch physician who first described it in detail. Despite the different names, all of these terms refer to the same important feature in the brain that plays a crucial role in language and sensory processing.
