<< review queue entry 62042 - submitted by 'richwarm' >> "The outer surface of the brain (cerebral cortex) is very ‘wrinkled’ (convoluted) so that a maximum amount of gray matter (brain neurons) can fit inside the skull. The convolutions consist of grooves called sulci and raised ridges in between called gyri." https://www.verywellmind.com/the-anatomy-of-the-brain-2794895 So sulci do not "divide the lobes of the brain" as our definition says (except in the case of the larger sulci, usually called fissures -- see Wp below). Also, it's the *cerebrum* that has lobes rather than the brain as a whole. "Sulci, the grooves, and gyri, the folds or ridges make up the folded surface of the cerebral cortex. Larger or deeper sulci are termed fissures ... The sulci and fissures are both grooves in the cortex but they are differentiated by size. A sulcus is a shallower groove that surrounds a gyrus. A fissure is a large furrow that divides the brain into lobes, and also into the two hemispheres as the longitudinal fissure." https://en.wikipedia.org/wiki/Sulcus_(neuroanatomy) This Wp article "Sulcus_(neuroanatomy)" is paired with the Chinese Wp article "腦溝". ------------------------------------- Bottom line: The gloss "sulcus" is correct, but the explanation of what a sulcus is, is wrong. It's best to simply label the entry as "(neuroanatomy)" and let people check the meaning in some authoritative source if they need to. |
