#Connectivity of #precuneus to the default mode and #dorsal #attention #networks: A possible invariant marker of #long-term #tinnitus
پژوهشگران نوروساینس دانشگاه ایلینویز 🇺🇸 در گزارشی که به تازگی منتشر شده است، بیان داشتند #پره_کونئوس (#پیش_گُوِه؛ ناحیه داخلی #کرتکس #آهیانه #بالایی) به #شبکه #خلفی #توجه مرتبط بوده و این بخش در افراد دارای #زنگ_گوش مزمن ارتباط خاصی با #شبکه #وضعیت #پایه ندارد.
این پژوهش بر 85 نفر داوطلب بین 30 تا 70 ساله با وضعیت های مختلف #شنوایی و در 6 گروه انجام شد. در بازه های زمانی 6 و 12 ماهه پیگیری نیز نتایج بدست آمده ثابت و پایا بودند.
Abstract
#Resting state #functional #connectivity studies of #tinnitus have provided #inconsistent evidence concerning its #neural bases. This may be due to differences in the #methodology used, but it is also likely related to the #heterogeneity of the #tinnitus #population. In this study, our goal was to identify resting state functional connectivity alterations that consistently appear across tinnitus subgroups. We examined two sources of variability in the subgroups: tinnitus severity and the length of time a person has had chronic tinnitus (referred to as tinnitus duration). Data for the current large-scale analysis of variance originated partly from our earlier investigations and partly from previously unpublished studies. Decreased correlations between seed regions in the default mode network and the precuneus were consistent across individuals with long-term tinnitus (who have had tinnitus for greater than one year), with more bothersome tinnitus demonstrating stronger decreases. In the dorsal attention network, patients with moderately severe tinnitus showed increased correlations between seeds in the network and the precuneus, with this effect also present in only some patients with mild tinnitus. The same effects were not seen in patients with mild tinnitus and tinnitus duration between 6 and 12 months. Our results are promising initial steps towards identifying invariant neural correlates of tinnitus and indexing differences between subgroups.
