Time after Time: Environmental Influences on the Aging Brain
A growing body of evidence suggests that neurological function in the elderly can be affected by exposures from years earlier. In some cases, contaminants stored in the body are released over time as a function of processes such as pregnancy and aging. In others, damage may occur with no evidence of effects until old age. Clockwise from top left:
متن کاملEnvironmental influences on cognitive and brain plasticity during aging.
In the current article, we provide a critical review of the extant literature that has focused on environmental influences on cognitive and brain plasticity over the adult life span. The review includes both human epidemiological, and human and nonhuman cross-sectional and longitudinal research. We review a number of factors that have been suggested to reduce age-related cognitive decline inclu...
متن کاملEnvironmental influences on skin aging and ethnic-specific manifestations
Skin aging does not only occur by passing time alone but also by the exposure to different environmental factors. The skin aging process, which is induced by environmental factors, is named premature or extrinsic skin aging process and can be distinguished from the chronologically (intrinsic) skin aging process by characteristic skin aging signs. Well known environmental factors leading to extr...
متن کاملGenetic influences on 'environmental' factors.
Childhood environment, social environment and behavior, leisure time activities and life events have been hypothesized to contribute to individual differences in cognitive abilities and physical and emotional well-being. These factors are often labeled 'environmental', suggesting they shape but not reflect individual differences in behavior. The aim of this study is to test the hypothesis that ...
متن کاملEnvironmental Influences on Epigenetic Regulation
Gametogenesis is a sexually dimorphic process requiring profound differences in germ cell differentiation between the sexes. In mammals, the presence of heteromorphic sex chromosomes in males creates additional sex-specific challenges, including incomplete X and Y pairing during meiotic prophase. This triggers formation of a heterochromatin domain, the XY body. The XY body disassembles after pr...
