Outline of Final Research Achievements |
The cerebral cortex is a functional network consisting of a vast number of long-range interactions between brain areas, and the influence at the level of this global network in consequence of local cortical inactivation remains unclear. We reversibly inactivated the macaque prearcuate cortex during functional magnetic resonance imaging experiments and detected the global influence on the network of functional connectivity (FC) between cortical areas across the whole brain. Our results showed that quantitative relations exist between the changes in FC between distant areas and the FC between the inactivated site and these areas in the no-inactivation condition, even in area pairs remote from the inactivated site.
