Functions of Connective Tissues01:17

Functions of Connective Tissues

16.6K
Connective tissues perform a broad range of functions in the body. Their primary function is to connect and link different tissues in the body and act as packaging material between tissues. The areolar tissue, a connective tissue prototype, commonly cements various tissue types in diverse body organs. In contrast, adipose tissue cushions internal organs while insulating the body from heat loss.
Hard connective tissues, such as bones and cartilage, provide structure and support to the body.

Network Function of a Circuit01:25

Network Function of a Circuit

698
Frequency response analysis in electrical circuits provides vital insights into a circuit's behavior as the frequency of the input signal changes. The transfer function, a mathematical tool, is instrumental in understanding this behavior. It defines the relationship between phasor output and input and comes in four types: voltage gain, current gain, transfer impedance, and transfer admittance. The critical components of the transfer function are the poles and zeros.

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,...

Conservation of Protein Domains Over Different Proteins

14.4K
Protein domains are small structurally independent units that are part of a single amino acid chain.  Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to...

Cognitive Dissonance01:38

Cognitive Dissonance

37.5K
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...

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:

  • Cognitive Neuroscience
  • Neuroimaging
  • Aging Research

Background:

  • Aging affects neurocognitive processes and neural efficiency.
  • Identifying neural correlates of cognitive function in aging is crucial.
  • Internetwork connectivity's role in cognitive aging requires further investigation.

Purpose of the Study:

  • To investigate if internetwork connectivity among cognitive networks is sensitive to age-related changes.
  • To examine the relationship between neural efficiency, cognitive functioning, and internetwork connectivity in aging.
  • To determine if network interactions are associated with cognitive task performance in older adults.

Main Methods:

  • Utilized a factor analytic connectivity approach to model network interactions.
  • Analyzed data from 11 cognitive tasks across four domains: vocabulary, perceptual speed, fluid reasoning, and episodic memory.
  • Examined internetwork connectivity among six cognitive networks.

Main Results:

  • Both age and task domain significantly influenced internetwork connectivity.
  • Specific connections among cognitive networks were associated with in-scanner task performance.
  • Internetwork connectivity patterns varied based on age and cognitive demands.

Conclusions:

  • Internetwork connectivity is dynamic and affected by aging and task demands.
  • Network connectivity is related to cognitive performance in aging.
  • Future research should explore multiple networks and tasks to understand cognitive aging and network flexibility.
