What is Evolutionary History?02:35

What is Evolutionary History?

43.0K
Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth and provides evidence for evolution. However, both fossil and living organisms offer evidence that outlines Earth’s evolutionary history.

lncRNA - Long Non-coding RNAs

9.8K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Cognitive Dissonance

36.8K
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...

Covalently Linked Protein Regulators

8.9K
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein....

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Computational Biology

Background:

  • Cognitive phenotypes (memories, beliefs, skills, preferences) result from complex histories.
  • These histories are physically encoded in brain structure via circuit modification.
  • Understanding this encoding is crucial for linking experience to brain function.

Purpose of the Study:

  • To introduce and formalize the concept of connectal coding.
  • To develop a statistical framework for analyzing brain network structures related to individual histories.
  • To demonstrate the broad applicability of connectal coding across different research areas.

Main Methods:

  • Development of a formal statistical framework for connectal coding.
  • Application of the framework to diverse datasets and experimental modalities.
  • Analysis of brain circuit structures in relation to historical influences.

Main Results:

  • Demonstration of a robust statistical approach for connectal coding.
  • Successful application across various experimental contexts and phylogenetic scales.
  • Identification of network structures linking cognitive phenomena to individual histories.

Conclusions:

  • Connectal coding offers a powerful method for understanding how life histories shape brain structure and cognitive function.
  • The proposed framework provides a quantitative approach to studying the neurobiological basis of individual differences.
  • This work bridges the gap between historical influences and observable brain and cognitive traits.
