Introduction: Attention and working memory are key cognitive functions that allow us to select and maintain information in our mind for a short time, being essential for our daily life and, in particular, for learning and academic performance. It has been shown that musical training can improve working memory performance, but it is still unclear if...

Humans often face the challenge of making decisions between ambiguous options. The level of ambiguity in decision-making has been linked to activity in the parietal cortex, but its exact computational role remains elusive. To test the hypothesis that the parietal cortex plays a causal role in computing ambiguous probabilities, we conducted consecut...

Background Self-regulation is a complex capacity that favors the modification of behavior in accordance with environmental demands. Objective This article aims to review the scientific literature that conceptualizes self-regulation, analyze its potential latent dimensions, identify the instruments used to measure this construct and the empirical f...

Very little has been written about the national pioneer investigators and the formal institutions and channels of knowledge that have contributed to the consolidation of cognitive neuroscience in Chile. This article is a review based on scientific publications, magazine articles and interviews with neuroscientists that were key to the development o...

Humans must often estimate reward values in the presence of ambiguous information to determine the best course of action. The degree of ambiguity during decision-making has been related to levels of activity in the parietal cortex, however, its specific computations and causal role remain unknown. We tested the hypothesis that the parietal cortex i...

Este artículo busca contribuir al proceso terapéutico de la Psicomotricidad Clínica en tiempos de pandemia, incorporando aportes del enfoque terapéutico Vincular Familiar (Messing, 2011; 2017). Para la comprensión de la globalidad psico-afectiva-motriz del infante se proponen componentes multidimensionales, asociados a la expresión psicomotriz, que...

Attention and working memory (WM) are core components of executive functions, and they can be enhanced by training. One activity that has shown to improve executive functions is musical training, but the brain networks underlying these improvements are not well known. We aimed to identify, using functional MRI (fMRI), these networks in children who...

RESUMEN El siguiente artículo analiza, desde una perspectiva epistemológica, cuáles son los posibles mecanismos que operan en la producción de investigaciones científicas de carácter biomédico aplica-das a niños y niñas, y cómo influyen en la interpretación de los resultados, causando eventuales consecuencias que distan de los discursos emancipador...

A dysfunction in the excitatory-inhibitory (E/I) coordination in neuronal assembly has been proposed as a possible neurobiological mechanism of Autistic Spectrum Disorder (ASD). However, the potential impact of this mechanism in cognitive performance is not fully explored. Since the main consequence of E/I dysfunction is an impairment in oscillator...
