First graders (aged 7-8) in a public elementary school served as subjects for this study. The structural components of their speech were analyzed to determine speech maturity level; total EEG activity was analyzed to assess the functional maturity of brain structures. Results showed that children with levels of speech below the age norm exhibited abnormal EEG patterns suggesting immaturity of the cerebral cortex and fronto-thalamic regulatory system, as well as impairments in the functioning of the mesodiencephalic structures and nonspecific activation systems. Abnormalities in the functioning of brain regulatory systems and the presence of local abnormalities in EEG activity of deep origin are important factors in determining the severity of functional speech impairments.
En el presente estudio participaron alumnos de primer grado de una escuela pública (7-8 años). Fueron analizados los componentes estructurales de su habla para determinar el nivel de madurez de la misma; se analizó la actividad total EEG para evaluar la madurez funcional de las estructuras cerebrales. Los resultados mostraron que niños con niveles de habla por debajo de la norma, presentaban patrones anómalos de EEG sugiriendo inmadurez en el cortex cerebral y en el sistema de reguladores frontotalámicos, así como mejora en el funcionamiento de las estructuras mesodiencefálicas y sistemas de activación no específicos. Las anomalías en el funcionamiento de los sistemas reguladores del cerebro y la presencia de anomalías locales en la actividad EEG de origen más profundo son factores importantes a la hora de determinar la severidad del deterioro en el habla.
