Summary: The study investigated the association between uncinate fasciculus fractional anisotropy (FA) and emotional recovery, as well as corrugator activity. It found that higher FA was linked to better recovery from negative provocation, and also identified potential associations between other white matter fibers and emotion regulation.

Summary: This study used multi-modal neuroimaging analyses to localize the cortical regions and white matter tracts responsible for auditory language comprehension. The results showed that cortical areas in the posterior temporal lobe are crucial for language comprehension. The fiber integrity of the arcuate fasciculus and the inferior longitudinal fasciculus was strongly correlated with auditory comprehension and the grey matter volume of the inferior temporal and middle temporal gyri.

Summary: Patients with Parkinson's disease hallucinations show significant white matter changes, particularly in posterior connections and thalamic nuclei. Cortical thickness changes are less extensive. Thalamic nucleus of the right medial mediodorsal showed both connectivity and volume loss in PD hallucinations.

Summary: This study is the first to explore the relationship between peripheral inflammation and white matter microstructure in fronto-cingulatelimbic tracts in depressed and nondepressed adolescents. The results show that depressed adolescents had higher levels of inflammation compared to controls, but there was no significant difference in white matter connectivity between the two groups. While there was an association between inflammation levels and white matter structure, the diagnostic group did not moderate this relationship.

Summary: The study found that adults with ADHD have focal abnormalities in white matter structures, particularly in areas related to visuospatial processing and memory, which may be associated with persistent ADHD symptoms.

Summary: The study identified differences in white matter microstructure between individuals with bipolar disorder type-II and unipolar depression, suggesting that these distinctions can help differentiate between the two mood disorders. Additionally, the research demonstrated the impact of depression and subthreshold mania interaction on white matter microstructure.

Summary: This study aimed to determine the relationship between the anterior terminations of the arcuate fasciculus (AF) and third branch of the superior longitudinal fasciculus (SLF-III) and the speech arrest sites induced by intraoperative direct cortical electrical stimulation (DCS). The results showed that the speech arrest sites were consistently associated with SLF-III anterior terminations and moderately associated with AF and AF/SLF-III complex terminations. The terminations of AF and SLF-III in healthy participants converged onto the ventral precentral gyrus anterior bank (vPCGa) and were able to predict the DCS speech output area.

Summary: The study constructs the first white matter atlas of a lesser ape using diffusion MRI and finds that the white matter architecture of the gibbon is similar to that of great apes, suggesting these features might have originated in their common ancestor approximately 16 million years ago and further developed in the evolution of great apes and humans.

Summary: Social anxiety disorder (SAD) is associated with changes in brain structural connectivity, with increased FDC in the right superior longitudinal fasciculus (SLF) and right inferior longitudinal fasciculus (R-ILF) regions. The study also revealed a correlation between white matter structural changes and symptom severity.

Summary: This study provides a comprehensive review of the role of white matter in connecting cortical areas involved in language processing. Hypotheses about the functions of major tracts connecting these areas are evaluated using data from studies in neurotypical individuals, neuropsychological data, and intraoperative stimulation studies. The study highlights the conclusions supported by the data and identifies areas requiring further investigation.

Summary: The development and persistence of laterality in human motor behavior, particularly in hand use, has been studied with a focus on the asymmetry in brain organization. Recent research utilizing diffusion magnetic resonance imaging has shown differences in white matter connectivity between left and right-handers, particularly in pathways related to visuomotor and visuospatial processing. Despite incomplete evidence, the study highlights the importance of exploring new avenues for understanding the neural basis of handedness.

Summary: The study did not find evidence to support the hypothesis that disconnection of white matter tracts underlies the association between vascular risk factor burden and depressive symptoms, highlighting the importance of using longitudinal data to directly test pathways linking vascular and mental health.

Summary: In very preterm-born children, neonatal thalamic growth and WMI volume predict school-age thalamic volumes. An interaction between FA and WMI impacts school-age thalamic volume, affecting cognition and motor outcomes.

Summary: This study compared the morphological and microstructural characteristics of each branch of the superior longitudinal fasciculus (SLF) in neonates and adults, using diffusion MRI data. The findings showed similar fiber morphology and connectivity in the SLF branches (excluding SLF II) between the neonatal and adult groups. The Mahalanobis distance values supported the idea of heterogeneous maturation among the SLF branches, with SLF II being the least mature.

Summary: Chronic subclinical inflammation is believed to play a role in schizophrenia. This study investigated the correlation between peripheral inflammatory markers (IM) levels and the integrity of brain regions in different stages of schizophrenia. The study did not find any correlations between IM levels and integrity of specific brain regions in schizophrenia spectrum disorders.
