'''Brodmann area 7''' is part of the [[parietal lobe|parietal]] [[cerebral cortex|cortex]] in the [[human brain]]. Situated posterior to the [[primary somatosensory cortex]] ([[Postcentral gyrus|Brodmann areas 3, 1 and 2]]), and superior to the [[occipital lobe]], this region is believed to play a role in [[visuo-motor coordination]] (e.g., in reaching to grasp an object). In addition, area 7 along with [[Brodmann area 5|area 5]] has been linked to a wide variety of high-level processing tasks, including activation in association with language use.<ref>{{cite web|last=Marley|first=Justin|title=Somatosensory Association Cortex – Brodmann Areas 5 and 7 – A Brief Literature Overview|url=http://theamazingworldofpsychiatry.wordpress.com/2011/08/01/somatosensory-association-cortex-brodmann-areas-5-and-7-a-brief-literature-overview/|date=August 2011}}</ref> This function in language has been theorized to stem from how these two regions play a vital role in generating [[conscious]] constructs of objects in the world.<ref>{{Cite book |last=Sommerhoff |first=Gerd |url=https://sk.sagepub.com/books/understanding-consciousness |title=Understanding Consciousness: Its Function and Brain Processes |publisher=SAGE Publications Ltd |year=2000 |isbn=978-0-7619-6775-0 |location=1 Oliver's YardLondon, 55 City Road, London EC1Y 1SP United Kingdom |pages=135–156 |doi=10.4135/9781446220177}}</ref>
 
Brodmann area 7 spans both the medial and lateral walls of the parietal cortex. The medial part of Brodmann area 7 is called [[precuneus]]. Laterally, it is called the [[superior parietal lobule]] (SPL). At the base of the SPL is the [[intraparietal sulcus]], below which is the [[inferior parietal lobule]] (IPL), which in turn divides into [[Brodmann area 39|Brodmann areas 39]] ([[angular gyrus]]) and [[Brodmann area 40|40]] ([[supramarginal gyrus]]).
