摘要：
Age-related changes in NADPH-diaphorase (NADPH-d)-positive neurons were examined in the auditory cortex of young (3 months old) and very old (36 months old) rats (strain Long Evans). In very old rats a significant reduction was found in the thickness of the auditory cortex, to 54% of that in young animals, as well as changes in the shape and configuration of nerve cell bodies and dendrites. Quantitative analysis demonstrated an age-related increase in the number of dendritic segments and dendritic branching points. The length of dendrites in NADPH-d-positive neurons and their density increased in very old rats. The total number of NADPH-cl-positive neurons within the Te 1 and Te 3 fields was 13% lower in the old rats than in the young.
