Cognitive and behavioural flexibility: neural mechanisms and clinical considerations

Area of Science:

• Neuroscience
• Cognitive Psychology

Background:

• Cognitive and behavioral flexibility are crucial for adapting thoughts and actions to environmental changes.
• Brain mechanisms supporting flexibility are studied using neuroimaging, behavioral, and animal models.

Purpose of the Study:

• To identify large-scale functional brain networks supporting cognitive and behavioral flexibility.
• To examine how flexibility is compromised in neurodevelopmental disorders, adolescent conditions, and dementias.
• To critically evaluate methods for enhancing flexibility.

Main Methods:

• Non-invasive neuroimaging techniques (e.g., fMRI).
• Behavioral assessments of cognitive flexibility.
• Pharmacological and lesion studies in animal models.
• Literature review of enhancement strategies.

Main Results:

• Identified key brain networks: lateral/orbital frontoparietal, midcingulo-insular, and frontostriatal regions.
• Flexibility deficits are observed in early-life neurodevelopmental disorders, adolescent-onset conditions, and late-life dementias.
• Evidence supports cognitive training, physical activity, and bilingualism as potential enhancers of flexibility.

Conclusions:

• Cognitive and behavioral flexibility relies on interconnected large-scale brain networks.
• Disruptions in these networks contribute to cognitive impairments across various neurological and psychiatric conditions.
• Interventions like cognitive training and lifestyle changes show promise for improving flexibility.
