In contrast to healthy controls, BD patients did not significantly deviate from the veridical center, regardless which hand was used to bisect horizontal lines. This finding indicates an atypical functional cerebral asymmetry in visuospatial attention in BD euthymia, supporting the idea of a dysfunction especially in the right fronto-parietal cortex.

Music-induced changes in functional cerebral asymmetries

Distinguishing medication‐free subjects with unipolar disorder from subjects with bipolar disorder: state matters

“…Furthermore, RSNs show consistency across different subject groups, analysis methods, and types of scanning protocols . Moreover, several RSNs have been implicated in mood disorders: the default mode network (DMN); the left and right lateralized frontoparietal networks (FPN); and the salience network (SN) …”

Reading related white matter structures in adolescents are influenced more by dysregulation of emotion than behavior

“…This finding suggests an altered involvement of neural circuits related to cognitive control processes related to this network, specifically monitoring and conflict-resolution processes (Dosenbach et al, 2008), which has been suggested previously (Sylvester et al, 2012) and may be one of the causes for reading comprehension deficit in individuals with mood disorders. Another possibility is dysfunction in functional connectivity of the fronto-parietal network in youth with mood disorders (Sylvester et al, 2012), and more specifically, the right fronto-parietal network (Tamnes et al, 2013, Najt et al, 2013), which also is involved in working memory and phonological processing (Tamnes et al, 2013). Because both the cingulo-opercular and fronto-parietal networks can be easily identified during rest (Dosenbach et al, 2008), a future study involving a resting-state functional connectivity analysis, complementing to the current structural connectivity study and focusing specifically on these networks and their association with reading scores, is needed to confirm this point.…”
