Summary
A new collaborative database, Phenowiki.org, addresses the lack of phenomics knowledge bases for neuropsychiatric research. It aims to facilitate knowledge sharing and prioritize endophenotypes for translational studies.
Area of Science:
- Neuroscience
- Psychiatry
- Bioinformatics
Background:
- Genomic knowledge bases have advanced rapidly, but higher-level phenomics knowledge bases remain underdeveloped.
- This gap hinders informatics strategies for neuropsychiatric research, limiting knowledge mining, representation, and phenotype prioritization.
- Existing knowledge bases often involve limited contributors, failing to leverage social collaborative knowledge-building.
Purpose of the Study:
- To develop a collaborative annotation database for representing and sharing empirical information on phenotypes crucial for neuropsychiatric research.
- To address the underdeveloped state of phenomics knowledge bases, particularly for complex neuropsychiatric syndromes.
- To facilitate the selection and prioritization of endophenotypes for translational research.
Main Methods:
- Development of a collaborative annotation database (www.Phenowiki.org) for empirical phenotype data.
- Focus on 'cognitive control' as a proof-of-concept construct relevant to multiple neuropsychiatric syndromes.
- Tabulation of empirical findings on heritabilities and measurement properties for cognitive task and rating scale indicators (n=449 observations).
Main Results:
- The Phenowiki.org database currently contains 449 observations on heritabilities and measurement properties of cognitive indicators.
- Established a proof-of-concept knowledge base focused on 'cognitive control' phenotypes.
- Demonstrated a method for collaborative annotation of empirical findings.
Conclusions:
- Phenowiki.org serves as an open resource to enable collaborative knowledge-building in neuropsychiatric research.
- The database aims to help investigators select and prioritize endophenotypes for translational studies.
- This initiative addresses the critical need for robust phenomics knowledge bases in molecular psychiatry.

01:17Cognitivism
Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process information is...

01:23Behavioral Genetics and Its Designs
Behavior genetics explores how genetic inheritance influences human behavior. It focuses on how genes, passed from parents to offspring, contribute to the development of behavioral traits and tendencies. This branch of genetics seeks to understand the complex interplay between inherited genetic factors and environmental influences in shaping our behaviors.
The primary methodologies used in behavior genetics include family studies, twin studies, and adoption studies, each providing unique...

01:23Cognition and Behavior
Social psychology examines the complex interplay between individual mental processes and social interactions. Historically, the field was divided into two domains: social behavior and social cognition. Researchers focusing on social behavior analyzed actions within social contexts, such as conformity, aggression, or cooperation. Meanwhile, social cognition researchers investigated how people perceive, interpret, and mentally represent their social environments. However, modern perspectives no...
01:21Cognitive Learning
Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.

01:29Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu
Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...
02:27Background and Environment Affect Phenotype
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
