Insights

Individuals born very preterm (<32 weeks gestation) show lasting deficits in cognitive control and reduced brain network integration into adulthood. These findings highlight the need for continued support for very preterm individuals.

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Medical Imaging

Background:

  • Very preterm (VPT) birth (<32 weeks gestation) poses risks for long-term neurodevelopmental outcomes.
  • Cognitive control and brain network topology are crucial for adaptive functioning.
  • Longitudinal studies are essential to understand the lasting impacts of VPT birth.

Purpose of the Study:

  • To investigate the long-term effects of VPT birth on cognitive control and structural brain network topology at 26 years of age.
  • To examine brain-behavior associations between cognitive control and brain network characteristics in VPT and full-term (FT) individuals.
  • To identify potential targets for intervention to mitigate neurodevelopmental impacts of preterm birth.

Main Methods:

  • Utilized data from the Bavarian Longitudinal Study (BLS) including 61 VPT and 79 FT individuals.
  • Assessed cognitive control using multi-group confirmatory factor analysis.
  • Analyzed structural brain network topology via diffusion-weighted MRI, tractography, and graph-theoretic analysis.

Main Results:

  • Full-term individuals scored significantly higher in cognitive control speed compared to the very preterm group (0.742 SD difference, p=0.001).
  • The very preterm group exhibited reduced structural network integration, evidenced by lower global efficiency and average degree.
  • No significant group differences were found in network segregation (clustering coefficient).

Conclusions:

  • Very preterm birth is associated with persistent cognitive control deficits and impaired structural brain network integration in adulthood.
  • Structural brain network characteristics were not significantly linked to cognitive control abilities in this cohort.
  • Findings emphasize the necessity of ongoing support and interventions for individuals born very preterm to address lasting neurodevelopmental consequences.

Revisionist Views of Adolescent and Adult Cognition

A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...

Cognitive Dissonance01:38

Cognitive Dissonance

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Protein Networks02:26

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Network Covalent Solids

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...
