PHYSIOLOGICAL ALTERATIONS OCCURRING UNDERLYING PROCESS OF AGING

Abstract

Aging is an irreversible and universal phenomenon of every living organism’s
life. Many recent studies provide evidences that is strictly related to decline in cognitive function
impairment but along with various causes behind these abnormal changes, change in brain
!unction and structure is one of the most important factors are being widely used to study
the hypothesis that ‘the deficits in and temporal order memory are closely related. Increase
in age causes reduction in memory processing tasks, which involve information storage and
processing. In other explanation it is mentioned that frontal activity, differences underlying
aging is associated with recruitment of brain areas and neural circuit efficiency reduction. In
case of young subjects increase in activity mean shorter reaction time but in older subjects
results are opposite.
