Associated with aging changes in hemispheric organization of short-term memory in males and females

Author Affiliations


The effectiveness of hemispheric memory processes and the intensity of the orienting reaction and their relationships were studied in young and elderly subjects. A decreased overall performance in all memory tests and increase in the intensity of the orienting reaction were observed in the older group. The greatest changes in these characteristics were associated with the right hemisphere of the brain. Gender differences were shown in the greater safety of verbal left hemisphere functions in women compared to men in old age. Only in older women the relationship between the memory for words from the left ear with orientating reaction to the left lateralized stimuli has been found.
