Cognición, pero no afecto, descansa sobre una arquitectura de red intrínseca segregada
bioRxiv : the preprint server for biology
|February 23, 2026
Resumen
La cognición depende de una arquitectura de red cerebral segregada para funciones especializadas. Los procesos afectivos, sin embargo, pueden utilizar mecanismos de red cerebral más distribuidos para su mantenimiento.
Área de la Ciencia:
- Neurociencia
- Ciencia Cognitiva
- Psicología
Sus antecedentes:
- Las redes en estado de reposo (RSN) son cruciales para el soporte cognitivo fuera de línea.
- La segregación y la integración de la red son vitales para un comportamiento especializado y flexible.
- La investigación limitada vincula la organización intrínseca de las RSN con las diferencias conductuales individuales.
Objetivo del estudio:
- Investigar la asociación entre la organización intrínseca de las RSN y el mantenimiento conductual.
- Explorar cómo la segregación y la integración de la red se relacionan con los rasgos cognitivos y afectivos.
Principales métodos:
- Se utilizaron datos de imágenes de resonancia magnética funcional (fMRI) en estado de reposo del Proyecto Connectome Humano.
- Se realizó la predicción de la conectividad funcional del comportamiento en cognición, emoción y personalidad.
- Se empleó GINNA, un atlas de 33 RSN, para evaluar la segregación y la integración de la red.
Principales resultados:
- La conectividad conductual se organizó en tres dimensiones latentes: Cognición, Afecto Positivo y Afecto Negativo.
- La cognición, pero no el afecto, se relacionó con la segregación global de la red y la reducción de la integración.
- La cognición implicó la segregación de las RSN de nivel superior y la integración de las redes visuales de nivel inferior.
Conclusiones:
- La cognición está respaldada por una arquitectura cerebral intrínseca segregada, que facilita la especialización modular.
- Los procesos afectivos parecen depender de mecanismos distribuidos en las redes cerebrales intrínsecas.
- Los hallazgos refuerzan el papel de la arquitectura cerebral segregada en el apoyo a las funciones cognitivas.

Organization of the Brain
2.8K
The brain is an integral component of the nervous system and serves as the center for processing sensory inputs, making decisions, and directing bodily actions. This complex organ is organized into three primary sections: the hindbrain, midbrain, and forebrain, each responsible for a range of vital functions.
Hindbrain
The hindbrain, located at the base of the brain, plays a vital role in regulating automatic processes that sustain life. It includes the medulla oblongata, which is essential for...

Storage

A schema is a mental framework that helps individuals organize and interpret information. Schemata, formed from previous experiences, influence how we process new information: how we encode it, the inferences we make, and how we retrieve it. For instance, a schema for what a typical classroom looks like might include desks, a teacher's desk, a whiteboard, and students in such an environment. This expectation helps us quickly understand and navigate new classrooms without needing to analyze...

Cerebral Hemispheres
2.6K
The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...

Introduction to Cognitive Psychology
2.8K
Cognitive psychology is the field of psychology dedicated to examining how people think. It attempts to explain how and why we think the way we do by studying the interactions among human thinking, emotion, creativity, language, and problem-solving, as well as other cognitive processes. Cognitive psychology studies how information is processed and manipulated in remembering, thinking, and knowing.
This field emerged in the mid-20th century, following a period dominated by behaviorism, which...

Neural Circuits
3.0K
Neural circuits and neuronal pools are two of the main structures found in the nervous system. Neural circuits are networks of neurons that work together to carry out a specific task or process. They consist of interconnected neurons and glial cells, which provide structural and metabolic support.
Neuronal pools are collections of nerve cells with similar functions and interact through chemical and electrical signals. These pools include both interneurons (the central neural circuit nodes that...

Somatosensory, Motor, and Association Cortex
2.9K
The somatosensory cortex in the parietal lobes is crucial for interpreting sensory data such as touch, temperature, and proprioception. The somatosensory cortex, situated in the parietal lobes, plays a vital role in interpreting sensory information like touch, temperature, and proprioception—awareness of body position. This specialized brain region features an organized structure wherein neurons at the top primarily process sensations originating from the lower body. In contrast, those at...
