precuneus

Noun

precuneus (plural precunei)

1. A division of the medial surface of the parietal lobe of the cerebrum.
   • The precuneus becomes less active during goal-directed cognitive or perceptual tasks, suggesting it is selectively reducing awareness of potentially distracting environmental factors (Gusnard and Raichle, 2001).2010, David L. Clark, Nash N. Boutros, Mario F. Mendez, The Brain and Behavior: An Introduction to Behavioral Neuroanatomy, 3rd edition, Cambridge University Press, page 44
   • The logistic regression model revealed that reduced rCBF^([regional cerebral blood flow]) in the inferior parietal lobule, angular gyrus, and precunei had high predictive values and discriminative ability of converters to nonconverters.2013, John T. O'Brien, Louise Grayson, “Mild Cognitive Impairment and predementia syndromes”, in Tom Dening, Alan Thomas, editors, Oxford Textbook of Old Age Psychiatry, page 420
