Precuneus
Precuneus
The Precuneus (pronunciation: pre-KYOO-nee-us) is a part of the superior parietal lobule in the human brain situated in the medial aspect of each cerebral hemisphere, posterior to the paracentral lobule and anterior to the cuneus.
Etymology
The term "Precuneus" is derived from the Latin words "pre" meaning "before" and "cuneus" meaning "wedge". This is in reference to its position anterior to the cuneus in the brain.
Function
The Precuneus is involved in a variety of complex cognitive functions, including visuospatial processing, episodic memory, reflections upon self, and aspects of consciousness. It is one of the most metabolically active regions of the brain, and its activity is significantly reduced in conditions such as Alzheimer's disease and schizophrenia.
