The cerebral cortex was not depicted in a realistic manner until the 17th century with the Sylvian fissure being first accurately painted by [[Girolamo Fabrici d'Acquapendente]] in 1600 to provide plates for his ''Tabulae Pictae''.<ref name="Collice ">{{cite journal | last1 = Collice | first1 = M | last2 = Collice | first2 = R | last3 = Riva | first3 = A. | year = 2008 | title = Who discovered the sylvian fissure? | journal = Neurosurgery | volume = 63 | issue = 4| pages = 623–8 | doi = 10.1227/01.NEU.0000327693.86093.3F | pmid = 18981875 }}</ref><ref name="pmid17058037">{{Cite journal  | last1 = Zanchin | first1 = G. | last2 = De Caro | first2 = R. | title = The nervous system in colours: the tabulae pictae of G.F. d'Acquapendente (ca. 1533-1619). | journal = J Headache Pain | volume = 7 | issue = 5 | pages = 360–6 |date=Oct 2006 | doi = 10.1007/s10194-006-0340-0 | pmid = 17058037 | pmc=3468184}}</ref><ref name="Riva-2007">{{Cite journal  | last1 = Riva | first1 = A. | title = G.F. d'Acquapendente tabulae pictae on the nervous system. | journal = J Headache Pain | volume = 8 | issue = 4 | pages = 253–4; author reply 255–6 |date=Sep 2007 | doi = 10.1007/s10194-007-0408-5 | pmid = 17906833 | pmc=3451669}}</ref>

[[File:J. Voort Kamp in Caspar Bartholin Institutiones Anatomicae.png|thumb|right|The engraving by J. Voort Kamp published in 1641 that led to the lateral sulcus being named after [[Franciscus Sylvius]] ]]Its first description is traditionally taken to be in 1641, possibly by [[Caspar Bartholin the Elder|Caspar Bartholin]], where its discovery was attributed to [[Franciscus Sylvius]] (1614–1672), professor of medicine at [[Leiden University]] in the book ''Casp. Bartolini Institutiones Anatomicae'' where it is noted that "F.S. [F.S. probably refers to Franciscus Sylvius] If you examine the indentations which are represented in Figure 5 quite attentively, you will notice that they are very deep and that the brain is divided from one side to the other by the 'anfractuosa fissura,' which starts in the front part near the ocular roots, and from there moves backwards above the base of the spinal cord, following the temporal bones, and it divides the upper part of the brain from the lower."<ref name="Collice "/>

It seems likely, however, that, since Caspar Bartholin died in 1629 and Franciscus Sylvius only started medicine in 1632, these words are by either Caspar's son [[Thomas Bartholin]] or Franciscus Sylvius himself. In 1663 in his ''Disputationem Medicarum'', Sylvius described the lateral fissure: "Particularly noticeable is the deep fissure or hiatus which begins at the roots of the eyes (oculorum radices) . . . it runs posteriorly above the temples as far as the roots of the brain stem (medulla radices). . . . It divides the cerebrum into an upper, larger part and a lower, smaller part".<ref name="Collice "/>
