Resumen
El equilibrio del lenguaje impacta las redes cerebrales bilingües. Los bilingües desequilibrados utilizan recursos de control cognitivo más generales para el cambio de idioma, a diferencia de los bilingües equilibrados.
Área de la Ciencia:
- La neurociencia
- Ciencias cognitivas
- Psicolingüística
Sus antecedentes:
- Las redes de control de lenguaje bilingüe están bien estudiadas.
- Se propone que el equilibrio lingüístico sea un factor crítico que influya en estas redes.
- Los fundamentos neuronales de cómo el equilibrio lingüístico afecta el control bilingüe siguen siendo poco explorados.
Objetivo del estudio:
- Investigar cómo el equilibrio del lenguaje modera la base neuronal del control del lenguaje bilingüe.
- Identificar patrones de activación neuronal compartidos y distintos entre bilingües equilibrados y desequilibrados.
Principales métodos:
- Se realizó un metanálisis de los estudios de resonancia magnética funcional (fMRI).
- Se utilizó el software ALE de jengibre para analizar los datos de IRMf.
- El equilibrio lingüístico fue incorporado como factor moderador.
Principales resultados:
- Tanto los bilingües equilibrados como los desequilibrados comparten la activación en el giro frontal precentral y medial izquierdo.
- No se encontró una mayor convergencia de activación en los bilingües equilibrados para tareas específicas de dominio.
- Los bilingües desequilibrados mostraron una mayor convergencia de activación en el giro frontal medio izquierdo, el giro frontal inferior y el precuneo.
Conclusiones:
- El equilibrio del lenguaje modifica significativamente los mecanismos neuronales del control del lenguaje bilingüe.
- Los bilingües desequilibrados parecen reclutar más recursos de control cognitivo de dominio general.
- Los hallazgos destacan el papel de la distribución del dominio del lenguaje en la configuración de la función cerebral bilingüe.

Language and Cognition
438
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.

Lateralization
460
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

Higher Mental Functions of the Brain: Language

Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Language Development

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...
