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:

Environmental Influences on Mountain Gorilla Time Budgets

Data on the time budgets of mountain gorillas (Gorilla gorilla beringei) were collected during field studies in the Virunga Volcanoes region of Rwanda and Zaire. Focal sampling was used to determine the proportion of time that individuals of different agehex classes spent in several mutually exclusive activity states. The gorillas spent the majority of daylight hours feeding; most of the rest o...

Environmental 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...

Effect of Estrogen and Progesterone on Cytokines Levels at Different Time Intervals after Traumatic Brain Injury

Introduction: Following a traumatic brain injury (TBI), the excessive release of proinflammatory cytokines is major cause of cerebral edema that can cause permanent neuronal loss. This study examined the changes in brain concentrations of proinflammatory cytokines IL-1, IL-6, TNF-α and TGF- after different doses of estrogen or progesterone treatment in brain-injured rats at 6 and 24 h post...

The Effects of Aging and Brain Damage on Time Perception

The effects of aging and brain damage on time perception are not well understood. In this study, we test the hypothesis that aging affects timing variability and that parietal damage affects timing magnitude. Young and healthy college-age students, older subjects, and a patient with bilateral parietal damage were assessed on their ability to estimate and produce time intervals ranging from four...
