Effects of rearing complexity on dendritic branching in frontolateral and temporal cortex of the rat

摘要: Abstract Dendritic branching was studied in Golgi-stained neurons from frontolateral and temporal cortex of rats reared for 30 days after weaning complex, social, or isolated environments. In cortex, layer-4 pyramidal complex environments had significantly more basal dendritic branches than those littermates socially isolation. Layer-5 showed similar rearing effects. contrast, no significant differences due to were detected frontal cortex. both regions, there a high degree concordance within litters. These results amplify previous studies indicate that: the effects environmental complexity on are not restricted previously seen visual cortex; all cortical areas neuronal populations as might be expected if they reflected general hormonal nutritional difference; non-universality relative litters suggest that equivalent stained different groups.
