The Neurobiology of Working Memory Across the Adult Lifespan
How do changes in the brain that occur throughout life impact memory?
Working memory is the ability to store information in memory for short periods of time in order to complete a task, such as remembering directions. The amount of information able to be held in working memory is fundamental for cognitive performance, and accounts for approximately 45% of overall intelligence in healthy individuals.
Although generally stable, working memory capacity changes occur with aging and prominent declines are seen in later life. During this time, changes in the brains ability to generate oscillations (a.k.a. brain waves) also occur.
This project aims to identify whether these changes in the brain’s function underlie changes seen in working memory across key life stages: early adulthood (20-35 years) and later adulthood (65-85 years).
The project team will use a range of different measures in order to test this including: obtaining images of the brain with magnetic resonance imaging (MRI), recording the brain's activity using electroencephalography (EEG) (a cap placed on the scalp), and a brain stimulation method that uses a magnetic field to activate specific regions of the brain known as transcranial magnetic stimulation (TMS).
Understanding working memory capacity changes across the healthy adult lifespan may be able to aid in the development of interventions to treat age-related neurological disorders.
