| calcarine fissure | A deep fissure on the medial aspect of the cerebral cortex, extending on an arched line from the isthmus of the fornicate gyrus back to the occipital pole, marking the border between the lingual gyrus below and the cuneus above it. The cortex in the depth of the sulcus corresponds to the horizontal meridian of the contralateral half of the visual field. Synonym: sulcus calcarinus, calcarine fissure, fissura calcarina, posthippocampal fissure. (05 Mar 2000) |

| calcidiol | 25-hydroxycholecalciferol (a 3,25-diol);the first step in the biological conversion of vitamin D3 to the more active form, calcitriol; it is more potent than vitamin D3. Synonym: 25-hydroxycholecalciferol, calcifediol. Calcidiol 1a-hydroxylase, 25-hydroxycholecalciferol 1a-hydroxylase, the monooxygenase that forms calcitriol from calcidiol using O2 and NADPH; a deficiency in this enzyme can result in features of a vitamin D deficiency.
