Las personas con problemas de procesamiento del habla tras un ictus no tardaban m\u00e1s en analizar los sonidos, pero su procesamiento era mucho m\u00e1s d\u00e9bil que el de los participantes sanos. Esto indica que pueden o\u00edr los sonidos con normalidad, pero tienen dificultades para integrarlos y\u00a0convertirlos en lenguaje comprensible.<\/p>\n<p><a><\/a><\/p>\n<h2>Patrones de actividad cerebral<\/h2>\n<p>Adem\u00e1s, cuando exist\u00eda incertidumbre sobre qu\u00e9 palabras se estaban diciendo, las personas sanas manten\u00edan el procesamiento de las caracter\u00edsticas sonoras durante m\u00e1s tiempo que quienes hab\u00edan sufrido un ictus.
