Abstract

The absolute squares of cingulate cortex (anterior, posterior ventral, posterior dorsal, retrosplenial regions) were calculated on magnetic resonance images of 29 subjects (60-76 years old) and compared with subjects’ neuropsychological memory characteristics. The results demonstrate significant correlations between overall performance and the amount of different types of errors in neuropsychological memory tests and the relative size of these regions. The discovered correlations pattern can be explained by a hypothesis of reciprocal functional influence of two major areas of cingulate cortex (anterior and dorsal posterior regions) on the processes of external and internal interference, which results in neuropsychological memory tests performance.
