Transient and linearly graded deactivation of the human default-mode network by a visual detection task
KD Singh, IP Fawcett - Neuroimage, 2008 - Elsevier
In this fMRI study, we show that an extended network of brain areas, previously described as
the default-mode network, is suppressed during the performance of a global visual motion …

Exploring the brain in pain: activations, deactivations and their relation
The majority of neuroimaging studies on pain focuses on the study of BOLD activations, and
more rarely on deactivations. In this study, in a relatively large cohort of subjects (N= 61), we …

Transient suppression of broadband gamma power in the default-mode network is correlated with task complexity and subject performance
Task performance is associated with increased brain metabolism but also with prominent
deactivation in specific brain structures known as the default-mode network (DMN). The role …
