Control of cortical synchronization by wide threshold reduction

For the understanding of the control mechanism of cortical synchronization, we constructed the neural network having realistic architecture of the cerebral cortex. In the cortical model, paired outer inputs generated paired oscillations having anti-phase with each other. But the wide threshold reduction of excitatory units in the model promoted the synchronization of the paired oscillations. The results showed that the synchronization of multiple event-specific oscillations could be controlled by the wide excitation of the cerebral cortex. The control mechanism explained the basis of selective association and memory in the brain.
