Effect of cognitive task on delta and beta EEG synchronization
Synchronization as a measure of quantification of similarities in dynamic systems is an important concept in many scientific fields such as neuroscience. A new measure of synchronization, fuzzy SL, was used to investigate overall cortical functional connectivity during a cognitive task compared to resting conditions. High-resolution electroencephalogram (EEG) was recorded during eyes-open resting (EO1), continuous performance test (CPT), and eyes-open resting again (EO2) in 16 healthy children. Global fuzzy SL for delta and beta bands was calculated per condition. The opposite pattern was observed within conditions; delta increased but beta decreased from the EO1 to CPT condition. From the CPT to EO2, changes in the synchronization were also opposite. The findings might be interpreted as condition-specific modulation of functional connectivity of brain neuronal networks.
