|January 23, 2026
Resumen
La participación flexible del estado cerebral apoya el control cognitivo en diversos trastornos psiquiátricos. Esta flexibilidad de la red cerebral es clave para adaptar las respuestas, ofreciendo información sobre las variaciones en la salud mental.
Área de la Ciencia:
- Neurociencia
- Psiquiatría
- Psiquiatría Computacional
Sus antecedentes:
- El control cognitivo es crucial para la adaptación, pero su base neuronal en los trastornos psiquiátricos no está clara.
- El control cognitivo alterado es una característica común en diversas condiciones de salud mental.
- Comprender los mecanismos neuronales es vital para desarrollar intervenciones específicas.
Objetivo del estudio:
- Investigar si el reclutamiento flexible de los estados cerebrales sirve como un fenotipo intermedio para el control cognitivo.
- Examinar esta relación en muestras psiquiátricas transdiagnósticas.
- Identificar redes neuronales compartidas que sustentan la flexibilidad del control cognitivo.
Principales métodos:
- Se utilizó aprendizaje automático y validación externa en tres conjuntos de datos independientes (N>600).
- Se evaluaron componentes del control cognitivo (inhibición, cambio) utilizando datos de tareas y cuestionarios.
- Se empleó modelado predictivo basado en conectomas y se analizaron las dinámicas de la red cerebral.
Principales resultados:
- La participación flexible del estado cerebral predijo de manera robusta las métricas de control cognitivo en todos los conjuntos de datos y grupos de participantes.
- Las redes cerebrales compartidas sustentaron la participación flexible del estado cerebral de manera transdiagnóstica.
- La alineación temporal de la participación flexible del estado cerebral y la conectividad de la red se correlacionó con un mejor control cognitivo.
Conclusiones:
- La participación flexible de los estados cerebrales es un fenotipo intermedio robusto para el control cognitivo.
- Esta flexibilidad apoya tanto las diferencias interindividuales como las intraindividuales en el control cognitivo.
- Los hallazgos ofrecen un mecanismo neural transdiagnóstico que vincula la dinámica cerebral con la función cognitiva en la salud mental.

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...

Prediction Intervals
3.3K
The interval estimate of any variable is known as the prediction interval. It helps decide if a point estimate is dependable.
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.

Language and Cognition
741
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Cognitive Therapy
940
Cognitive therapy, pioneered by Aaron T. Beck in the 1960s, is a structured approach to addressing psychological distress by focusing on the influence of thoughts on emotions and behaviors. All cognitive therapies involve the basic assumption that human beings have control over their feelings, and that how individuals feel about something depends on how they think about it. Unlike psychoanalytic methods that delve into unconscious processes or humanistic approaches emphasizing...

Cognition and Behavior
311
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...
