What is the default network of the brain and how is it related to poorer performance of cognitive tasks in older adults?

ANSWER:


The default network of the brain refers to the areas of the brain that are most active when one is at rest and not engaged in any cognitive task. Older individuals have more problems than younger people suppressing this default network. For example, when a younger begins an engaging and challenging cognitive task, the default network is suppressed. Older adults show less suppression, resulting in poorer performance overall. Increased frontal activity in older adults may be one way they work around this lack of suppression.
