Csernansky, Paul M. Thompson, Jessica A. Turner, Lei Wang

Summary: Schizophrenia is associated with significant shape differences in subcortical brain structures, specifically more-concave-than-convex shapes in the hippocampus, amygdala, accumbens, and thalamus in individuals with schizophrenia. The study also found exaggerated patterns of asymmetry in schizophrenia patients compared to healthy controls, as well as associations between medication dosage and positive symptom levels with subcortical shape differences. These findings suggest common neural mechanisms may contribute to gray matter reduction in schizophrenia.

Neuroimaging studies within Cognitive Genetics Collaborative Research Organization aiming to replicate and extend works of ENIGMA

Daisuke Koshiyama, Kenichiro Miura, Kiyotaka Nemoto, Naohiro Okada, Junya Matsumoto, Masaki Fukunaga, Ryota Hashimoto

Summary: Reproducibility is crucial for generalizing the findings of clinical research, but neuroimaging studies are often characterized by low reproducibility. To address this issue, the international neuroimaging consortium, Enhancing Neuroimaging Genetics through Meta-Analysis (ENIGMA), established standard protocols for imaging analysis and conducted meta- and mega-analyses of psychiatric disorders with large sample sizes. The Cognitive Genetics Collaborative Research Organization (COCORO) in Japan has replicated and expanded upon the work of ENIGMA in the field of neuroimaging studies. Further collaboration between ENIGMA and COCORO will contribute to the generalization of their research findings.

Increased functional connectivity between presupplementary motor area and inferior frontal gyrus associated with the ability of motor response inhibition in obsessive-compulsive disorder

Hirofumi Tomiyama, Keitaro Murayama, Kiyotaka Nemoto, Mayumi Tomita, Suguru Hasuzawa, Taro Mizobe, Kenta Kato, Aikana Ohno, Sae Tsuruta, Osamu Togao, Akio Hiwatashi, Tomohiro Nakao

Summary: Recent evidence suggests that the presupplementary motor area (pre-SMA) and inferior frontal gyrus (IFG) play an important role in response inhibition. No study has investigated the relationship between these brain networks at resting-state and response inhibition in obsessive-compulsive disorder (OCD). The study found that OCD patients exhibit different associations between the ability of motor response inhibition and the functional connectivity between pre-SMA and IFG, indicating altered functional connectivity may contribute to impaired motor response inhibition in OCD.

The role of visual attention in dyslexia: Behavioral and neurobiological evidence

Nikolay Taran, Rola Farah, Mark DiFrancesco, Mekibib Altaye, Jennifer Vannest, Scott Holland, Keri Rosch, Bradley L. Schlaggar, Tzipi Horowitz-Kraus

Summary: This study aimed to investigate the role of visual attention in fluent reading in children with dyslexia and typical readers. The results indicate that visual attention plays an important role in reading comprehension. Typical readers showed stronger functional connectivity, which was associated with higher reading comprehension, while children with dyslexia did not display this pattern. This suggests that children with dyslexia have difficulties in the integration of executive functions, visual attention, and reading-related networks.
