La influencia del estrés cognitivo-metabólico en el sistema microbiota-intestino-cerebro

Abstract

The written language domain is based on the consolidation of complex neural representations of words orthographic patterns. Here, we studied the characteristics and differences of the neural activation levels that occur in the neural processes related to orthographic specialization, with functional magnetic resonance imaging, in each hemisphere, of 27 young adults with low and high orthographic abilities when they performed orthographic tasks. The results suggest that in highorthographic-performance participants’ left hemispheric neural activation does not vary between words and pseudohomophones; however, their neural activation significantly change while comparing incorrect vs. correct responses. None interhemispheric differences were found in loworthographic-performers when they execute the experimental tasks. Low-orthographicperformers tended to show more widespread neural activation than high-orthographicperformers in both hemispheres, along with higher variability in their neural activation associated to the performance of explicit tasks; nevertheless, there is not enough conclusive statistic evidence supporting these tendencies. The current study supports the notion of lateralized neural specialization developments underlying orthographic abilities.
