The evidence, for the involvement of the RH in melody-based treatment in the current study, is broadly consistent with findings from DTI studies showing an increase in the number of fibers in the right arcuate fasciculus in patients following MIT [20, 21].
The graph in Figure 3 shows that the tracts for the long fibres (red colour in the segmented illustration) connecting the posterior and anterior sections of the arcuate fasciculus bundle were significantly longer in the frequent hallucinating group compared to healthy controls, while there was no significant difference for patients with less frequent and severe hallucinations.
Antonio Francisco Cardim's Jesuit missionary map comes from his book Fasciculus e Japponicis floribus, which provided a unique tribute to Japan's late 16th and 17th century Jesuit martyrdom.
DTI analysis revealed a significant increase in mean, radial, and axial diffusivity, mainly of the fibers of bilateral anterior thalamic radiation and superior longitudinal fasciculus with left predominance, which intersected with bilateral subinsular white matter (P < 0.05).
In his printed version of 1482 Caxton completed the book with his Liber ultimus chapter, based in part on the synchronically arranged Fasciculus temporum, which relied on a diagrammatic mise-en-page that because it required precise replication was more suited to print than manuscript.
Their rationale was that, in the 1960s, subthalamic lesioning showed symptom relief in PD patients and a histological study they performed led them to believe they were aiming at the thalamic fasciculus. With this target, they reported treating 13 patients (Table 1).
Patients with PD had lower FA values in the left parietal WM, left middle cerebellar peduncle, inferior longitudinal fasciculus of the left occipital and right parietal lobe, left cingulum, forceps minor of the right frontal lobe, superior longitudinal fasciculus of the left frontal lobe, and midbrain.
