Precuneus

Trancred 2005 The function of the Precuneus is not clearly defined. Structures: Angular Gyrus Calcarine Sulcus Central Sulcus Cerebral Hemisphere Cingulate Gyrus Corpus Callosum Frontal Lobe Inferior Parietal Lobule Intraparietal Sulcus Lateral Fissure Occipital Lobe Parieto-occipital Sulcus Postcentral Gyrus Postcentral Sulcus Precuneus Primary Somatosensory Area Receptive Speech Area Superior Parietal Lobule Superior Temporal Sulcus Supramarginal Gyrus Information: The Parietal Lobe is located on the medial and lateral surfaces of the cerebral hemisphere between the frontal and occipital lobes. Boundaries: On the lateral surface it extends from the central sulcus anteriorly to an imaginary line drawn downwards from the parieto-occipital sulcus to the preoccipital notch. Inferiorly it is bounded by the lateral fissure and a horizontal line drawn from the lateral fissure to the imaginary line previously described. On the medial surface it is bounded by the frontal lobe anteriorly, the parieto-occipital fissure posteriorly and the corpus callosum and calcarine sulcus inferiorly. Gyri and Sulci: On the lateral surface the parietal lobe is formed by the postcentral gyrus and the superior and inferior parietal lobules. The postcentral gyrus is separated from the two parietal lobules by the postcentral sulcus, which is parallel to the central sulcus. The superior and inferior parietal lobules are separated from each other by the intraparietal sulcus. The inferior parietal lobule includes the supramarginal and angular gyri. The supramarginal gyrus hooks around the posterior surface of the lateral fissure and the angular gyrus hooks around the posterior end of the superior temporal sulcus. The medial surface of the parietal lobe includes an extension of the postcentral gyrus, the posterior part of the cingulate gyrus and the precuneus. Functional Areas: (1) Primary Somatosensory Area - located on the postcentral gyrus. (2) In the dominant hemisphere (usually the left) the lower part of the inferior parietal lobule is concerned with the perception and interpretation of language and forms part of the receptive speech (Wernicke's) area.
