Habitual digital media use and the brain: a meta-analysis.

Area of Science:

• Neuroimaging
• Cognitive Neuroscience
• Digital Media Studies

Background:

• The digital age and social media have spurred research into their effects on neurocognitive function.
• Existing studies often focus on reward, cognitive control, and socio-emotional brain systems.
• A systematic analysis of neuroimaging findings on digital media engagement is lacking.

Purpose of the Study:

• To conduct a broad, systematic analysis of neuroimaging studies on habitual digital media engagement.
• To identify consistent brain regions affected by digital media use through meta-analysis.
• To explore the role of the anterior insular cortex in digital media's neurocognitive impact.

Main Methods:

• Coordinate-based meta-analysis of published structural and functional MRI studies.
• Utilized Activation Likelihood Estimation (ALE) for data summation.
• Focused on studies investigating habitual digital media engagement.

Main Results:

• The most consistent neuroimaging effects were found in the anterior insular cortex.
• This region is crucial for integrating social and emotional information.
• Findings highlight the anterior insular cortex, a region not previously emphasized in digital media research.

Conclusions:

• Digital media engagement consistently affects the anterior insular cortex.
• This suggests a significant role for social and emotional integration in the brain's response to digital media.
• Further research should reconsider how the brain influences and is influenced by digital media and online behaviors.
