Citando:
"The precuneus is connected to the dorsal attention network – an area responsive to attention demanding tasks, and the default mode network, the area which is activated during less mentally strenuous activity.
“When the default mode network is on, the dorsal attention network is off, and vice versa. We found that the precuneus in tinnitus patients seems to be playing a role in that relationship,” said Sara Schmidt, a graduate student in the university’s neuroscience program.
For those suffering from chronic tinnitus, the precuneus is more closely connected to the dorsal attention network, than the default-mode network, MRI scans showed.
The research suggests that tinnitus sufferers are “not truly at rest, even when resting”, said Fatima Husain, lead researcher and on the study and a professor at the university."
