1828 J. Quain Elements Anat. x. 613 The angular part of the anterior lobe..is included between the internal termination of the fissure of Sylvius, the longitudinal fissure, and the commissure of the optic nerves.

1839–47 Todd's Cycl. Anat. & Physiol. III. 696/2 Two superior convolutions are met with above the fissure of Sylvius, between which is placed..the fissure of Rolando.

1849 S. G. Morton Illustr. Syst. Human Anat. 547 The insula [of Reil] consists of five or six small convolutions grouped and concealed within the Sylvian fissure.

1871 Huxley in Darwin Descent of Man (1874) vii. 204 In the human foetus, the sylvian fissure is formed in the course of the third month of uterogestation.

1888 W. R. Gowers Man. Dis. Nerv. Syst. II. iv. 6 Within the fissure of Sylvius lie the small convolutions of the island of Reil, or insula..four or five in number..which spread out like a fan.

1939 O. Larsell Textbk. Neuro-anat. XVIII. 219 The lateral fissure (fissure of Sylvius) opens to the hidden cortical surface of the island of Reil.

1980 A. Silverstein Human Anat. & Physiol. xiii. 278/2 Viewed from the side, the cerebrum looks something like a large mitten, with the wrist at the back and the fingers at the front of the head. The ‘thumb’ of the mitten is separated from the remainder by another prominent groove, the lateral fissure or fissure of Sylvius.
