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...

Intrinsically Disordered Proteins

19.6K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

Genetics of Speciation

Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.

Animal Mitochondrial Genetics

9.3K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Energy to Drive Translocation01:37

Energy to Drive Translocation

2.9K
Mitochondrial protein import is powered by two distinct energy sources: ATP hydrolysis and electrochemical potential across the inner membrane. Newly synthesized precursors are bound by cytosolic chaperones of the Hsp70 family, which guide them to the import receptors on the mitochondrial surface. Utilizing the energy of ATP hydrolysis, Hsp70 chaperones transfer these precursors to the TOM receptors on the mitochondrial outer membrane.
Generally, polypeptides are unfolded by two distinct...

Association Areas of the Cortex01:21

Association Areas of the Cortex

9.4K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Resumen
Este resumen es generado por máquina.

El riesgo genético para la psicopatología está relacionado con la cognición a través de vías específicas del trastorno, no de factores transdiagnósticos compartidos. Comprender estas influencias genéticas únicas es clave para descifrar la compleja relación entre la salud mental y la función cognitiva.

Área de la Ciencia:

  • Psiquiatría
  • Genética
  • Neurociencia Cognitiva

Sus antecedentes:

  • El funcionamiento cognitivo es crucial en la psicopatología pero poco estudiado.
  • Los déficits cognitivos a menudo cruzan los límites diagnósticos, lo que complica los vínculos específicos del trastorno.
  • La investigación genética puede diferenciar los efectos genéticos compartidos (transdiagnósticos) de los únicos.

Objetivo del estudio:

  • Identificar factores de riesgo genético transdiagnóstico y específico del trastorno para la psicopatología.
  • Examinar cómo el riesgo genético para la psicopatología se relaciona con el funcionamiento cognitivo a lo largo del desarrollo.

Principales métodos:

  • Se utilizó el modelado de ecuaciones estructurales genómicas.
  • Se derivaron puntuaciones poligénicas de una muestra longitudinal de gemelos (N=7764).
  • Se analizaron las asociaciones entre el riesgo genético y los dominios cognitivos.

Principales resultados:

  • Las relaciones psicopatología-cognición son impulsadas principalmente por el riesgo genético específico del trastorno.
  • Las asociaciones variaron en diferentes trastornos y dominios cognitivos.
  • Los análisis dentro de la familia revelaron vías distintas para estas asociaciones, algunas robustas a factores ambientales.

Conclusiones:

  • Los efectos genéticos específicos del trastorno son cruciales para comprender los vínculos entre psicopatología y cognición.
  • El riesgo genético transdiagnóstico es más relevante para los síntomas psiquiátricos que para la función cognitiva.
  • Centrarse únicamente en el riesgo transdiagnóstico pasa por alto la complejidad de los perfiles cognitivos en la psicopatología.
