Only a small part of the parieto-occipital sulcus, or parietooccipital fissure is seen on the lateral surface of the hemisphere, its chief part being on the medial surface. The lateral part of the parieto-occipital sulcus (Fig. 726) is situated about 5 centimeters (cm) in front of the occipital pole of the hemisphere, and measures about 1.25 cm. in length. The medial part of the parieto-occipital sulcus (Fig. 727) runs downward and forward as a deep cleft on the medial surface of the hemisphere, and joins the calcarine fissure below and behind the posterior end of the corpus callosum. In most cases it contains a submerged gyrus. The parieto-occipital sulcus marks the boundary between the cuneus and precuneus, and also between the parietal and occipital lobes. ==Function== The parieto-occipiatal lobe has been found in various neuroimaging studies, including PET (positron-emission-tomography) studies,〔 〕 and SPECT (single-photon emission computed tomography) studies, to be involved along with the dorsolateral prefrontal cortex during planning. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Parieto-occipital sulcus」の詳細全文を読む スポンサード リンク
