中文摘要	Objective: This work intends to evaluate the functional characteristics of the cerebral network during the successful memory encoding of TV commercials. Methods: We estimated the functional networks in the frequency domain from a set of high-resolution EEG data in a group of healthy subjects during the showing of commercial spots within a neutral documentary. We evaluated the differences in the cortical network associated with later remembered and not-remembered commercials by calculating the global-E-g and local-efficiency E-l indexes. Results: Successful encoding of TV spots significantly affects the functional communication among cortical areas irrespectively of the frequency band. During the visualization of the video-clips that will be forgotten (FRG), the cortical network exhibited high values of global- and local-efficiency, reflecting a small-world configuration. During the visualization of the video-clips that will be remembered (RMB), the same indexes appeared significantly lower. This difference was especially evident for E-l in the alpha band and for E-g in the beta and gamma bands. Conclusions: The presence of attentional and semantic processes during the RMB condition leads to a significant reduction of the network communication efficiency. Significance: Such a reduction could represent a predictive measure of accurate recalls of TV spots. (c) 2008 International Federation of Clinical Neurophysiology. Published by Elsevier Ireland Ltd.
