Gyri

Outermost, covering the entire cerebrum, is the gray matter, the cerebral cortex, an eighth-inch-thick landscape of rolling hills (known as gyri) and valleys (sulci). ❋ GERALD L. SCHROEDER (2001)

The ridges of cerebral tissue between the sulci, which look like softly rolled matter that has been flattened out slightly by the pressure of the skull, are called gyri (j'y'ry; "rolls" L), the singular form being gyrus (jy'rus). ❋ Asimov, Isaac (1963)

The lateral surface of the frontal lobe (Fig. 726) is tranversed by three sulci which divide it into four gyri: the sulci are named the precentral, and the superior and inferior frontal; the gyri are the anterior central, and the superior, middle, and inferior frontal. ❋ Unknown (1918)

The ridges in the cerebrum are called the gyri (gyrus) ❋ Ckkc09 (2010)

The convex parts of the folds are called gyri (singular, gyrus). ❋ Unknown (2010)

Bilateral activation in the inferior frontal and superior temporal gyri and activation in the left fusiform gyrus of girls was greater than in boys. ❋ Zoe Brain (2008)

I think the most recent time was when activity in certain areas of my brain (the claustrum, left caudate and putamen, right middle occipital/middle temporal gyri and bilateral cingulate gyrus) caused me, quite against my will, to become attracted to Susan from Narnia Episode IV (who turns out to be 17, so it's OK anyway). ❋ Amuchmoreexotic (2005)

They determine whether you are selecting the lobes, sulci (the 'trenches') or gyri (the 'ridges') when asking for on-screen labels. ❋ Unknown (2006)

The sulci and gyri are fairly standardized from brain to brain, and the more prominent ones are named and mapped. ❋ Asimov, Isaac (1963)

The sense of smell has been localized by Munk in the gyri hippocampi, while the center of hearing has been demonstrated to be in the temporal lobes. ❋ Various (N/A)

The Cranial Part (arachnoidea encephali) of the arachnoid invests the brain loosely, and does not dip into the sulci between the gyri, nor into the fissures, with the exception of the longitudinal. ❋ Unknown (1918)

This cavity is small on the surface of the hemispheres of the brain; on the summit of each gyrus the pia mater and the arachnoid are in close contact; but in the sulci between the gyri, triangular spaces are left, in which the subarachnoid trabecular tissue is found, for the pia mater dips into the sulci, whereas the arachnoid bridges across them from gyrus to gyrus. ❋ Unknown (1918)

The Superior Cerebral Veins (vv. cerebri superiores), eight to twelve in number, drain the superior, lateral, and medial surfaces of the hemispheres, and are mainly lodged in the sulci between the gyri, but some run across the gyri. ❋ Unknown (1918)

The basal vein is formed at the anterior perforated substance by the union of (a) a small anterior cerebral vein which accompanies the anterior cerebral artery, (b) the deep middle cerebral vein (deep Sylvian vein), which receives tributaries from the insula and neighboring gyri, and runs in the lower part of the lateral cerebral fissure, and (c) the inferior striate veins, which leave the corpus striatum through the anterior perforated substance. ❋ Unknown (1918)

These gyri constitute the cortical center for smell. ❋ Unknown (1918)

The parietotemporal supplies the supramarginal and angular gyri, and the posterior parts of the superior and middle temporal gyri. ❋ Unknown (1918)

The Cranial Pia Mater (pia mater encephali; pia of the brain) invests the entire surface of the brain, dips between the cerebral gyri and cerebellar laminæ, and is invaginated to form the tela chorioidea of the third ventricle, and the choroid plexuses of the lateral and third ventricles (pages 840 and 841); as it passes over the roof of the fourth ventricle, it forms the tela chorioidea and the choroid plexuses of this ventricle. ❋ Unknown (1918)

The anterior branches supply a part of the superior frontal gyrus, and send twigs over the edge of the hemisphere to the superior and middle frontal gyri and upper part of the anterior central gyrus. ❋ Unknown (1918)
