概要 | We demonstrate that both detection of weak visual signals to the right eye and phase synchronization of electro-encephalogram (EEG) signals from widely separated areas of the human brain are increased by addition of weak visual noise to the left eye. We found a close relationship between the resulting noise-induced changes in behavioural performance and the similarly resulting changes in phase synchronization between widely separated brain areas. These results imply that noise-induced large-scale neural synchronization may play a significant role in information transmission in the brain. |
