Analysis and Visualization of EEG Event-Induced Dynamic Synchronization Patterns in Cognitive Tasks

The execution of even simple cognitive tasks is characterized by the cooperation of different neural networks that are distributed across the brain, and whose synchronized activity generates oscillations of specific frequencies in the EEG [Kirschfeld, 2005]. Thus, in response to specific stimulae, o...
