Protein Networks02:26

Protein Networks

4.5K
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,...

Decision Making01:20

Decision Making

970
Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

Improving Translational Accuracy

14.9K
Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Network Covalent Solids02:18

Network Covalent Solids

16.2K
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...

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Decision Science

Background:

  • Innovative decision-making balances exploration and exploitation.
  • Executive functions, including working memory and attention, are crucial for this balance.
  • These functions are linked to fronto-parietal brain networks.

Purpose of the Study:

  • To assess if cognitive training targeting executive skills improves exploration-exploitation trade-off management.
  • To investigate if performance improvements correlate with neurostructural changes in fronto-parietal networks.

Main Methods:

  • 18 subjects underwent cognitive training and assessments; a control group did not.
  • A subgroup received multimodal MRI to examine grey-matter and white-matter changes.
  • Assessments included decision-making tasks and executive function evaluations.

Main Results:

  • Cognitive training enhanced innovative decision-making efficiency and executive control skills.
  • Improvements were associated with neurostructural changes in the right fronto-polar cortex and left superior longitudinal fasciculus.
  • These changes indicate training-induced plasticity in fronto-parietal networks.

Conclusions:

  • Ad-hoc cognitive training focusing on executive skills can enhance innovative decision-making quality.
  • Such training promotes neurostructural changes within fronto-parietal networks.
  • Findings have implications for managerial decision-making and clinical rehabilitation.
