| Research Abstract |
The present research has been undertaken to investigate age-related change of cognitive function in both humans and non-human primates on the basis of behavioral measurements and non-invasive neuroimaging techniques. Particularly, it has focused upon the inhibitory function and examined how response-inhibitory function declined according to aging. The study has revealed that it was not necessarily irreversible as a function of age in humans, but could be restored to the level that was equivalent to younger persons on some occasions. In such cases, neuroimaging measurements have indicated a corresponding increase of the neural activity in prefrontal regions. The experimentation with Simon task has also revealed a difference in the age-related difficulties between humans and non-human primates, and in some cases, the performance was superior in non-humans to in humans.
