Abstract(in English) | This study was conducted to explore the hypothesis that the perception and production of words is carried out by cell assemblies composed of neuronal groups distributed throughout the brain. It has been proposed that neural activity in the gamma frequency range may be responsible for binding neuronal groups that compose cell assemblies. In this study, gamma and alpha band scalp recorded EEG responses for auditory recognition and speech production planning of words and pseudowords were analyzed over single stimulus sweeps using measures of mutual information between electrode pairs and of integration (degree of statistical dependence across all elesctrodes). Consistent with the idea of cell assemblies, the results of both the mutual information and integration analyses suggest that distributed neuronal groups show greater statistical dependence for words than for pseudowords. |
