Impaired Cortical Network for Preattentive Detection of Change in Speech Sounds in Schizophrenia: A High-Resolution Event-Related Potential Study

Abstract

These results demonstrate impaired frontotemporal cortical networks for preattentive detection of change in speech sounds in schizophrenia. The language-related dysfunction in schizophrenia may be present at the early stage of auditory processing of relatively simple stimuli, such as phonemes, and not just at stages involving higher-order semantic processes.
