Brain Network Modularity During a Sustained Working-Memory Task

Spontaneous oscillations of the Blood Oxygenation Level-Dependent (BOLD) signal are spatially synchronized within specific brain networks and are thought to reflect synchronized brain activity. Networks are modulated by the performance of a task, even if the exact features and degree of such modulations are still elusive. The presence of networks showing anticorrelated fluctuations lend initially to suppose that a competitive relationship...
