The Prefrontal Cortex Basal Ganglia model of working memory states that the prefrontal cortex works hand-in-hand with the basal ganglia to accomplish the tasks of working memory. There have been many studies that have shown this to be the case. One study used ablation techniques in patients who had suffered from seizures and had damage to the prefrontal cortex and basal ganglia. Researchers found that damage done to these areas of the brain resulted in decreased patients’ abilities to carry out the executive function portion of working memory. <ref>{{Cite journal|last=Voytek|first=Bradley|last2=Knight|first2=Robert T.|date=2010-10-19|title=Prefrontal cortex and basal ganglia contributions to visual working memory|url=https://www.pnas.org/content/107/42/18167|journal=Proceedings of the National Academy of Sciences|language=en|volume=107|issue=42|pages=18167–18172|doi=10.1073/pnas.1007277107|issn=0027-8424|pmid=20921401}}</ref><ref>{{Cite journal|last=Baier|first=Bernhard|last2=Karnath|first2=Hans-Otto|last3=Dieterich|first3=Marianne|last4=Birklein|first4=Frank|last5=Heinze|first5=Carolin|last6=Müller|first6=Notger G.|date=2010-07-21|title=Keeping Memory Clear and Stable—The Contribution of Human Basal Ganglia and Prefrontal Cortex to Working Memory|url=https://www.jneurosci.org/content/30/29/9788|journal=Journal of Neuroscience|language=en|volume=30|issue=29|pages=9788–9792|doi=10.1523/JNEUROSCI.1513-10.2010|issn=0270-6474|pmid=20660261}}</ref> |

The Prefrontal Cortex Basal Ganglia model of working memory states that the prefrontal cortex works hand-in-hand with the basal ganglia to accomplish the tasks of working memory. There have been many studies that have shown this to be the case. One study used ablation techniques in patients who had suffered from seizures and had damage to the prefrontal cortex and basal ganglia. Researchers found that damage done to these areas of the brain resulted in decreased patients’ abilities to carry out the executive function portion of working memory. [1][2]
ADHD and mind-wandering
Mental disorders, such as ADHD, also go along with changes in different aspects of mind-wandering. Mental disorders, such as ADHD, are linked to mind-wandering. Seli et. al. found that spontaneous mind-wandering, the uncontrolled or unwarranted shifting of attention, is a characteristic of those who have ADHD. They note that deliberate mind-wandering, or the purposeful shifting of one's attention to different stimuli, is not a consistent characteristic of having ADHD because intentional shifting of cognitive capacities is not related to ADHD[3].
