Abstract

There is a marked decline in some intellectual abilities in old age. It is frequently hypothesized that impaired cerebral physiology accounts for some of this deficit. In old age the critical flicker frequency, a measure sensitive to cerebral dysfunction, is correlated with aging intellectual abilities. This is interpreted as evidence supporting the above hypothesis.
