We report the identical monozygotic twin cases of agenesis of the corpus callosum that demonstrated schizophrenic disorder. Patients were 26-year-old twin brothers and both cases were diagnosed as having schizophrenia using DSM-III-R diagnostic criteria. On magnetic resonance imagings both cases demonstrated the total agenesis of the corpus callosum and the anterior commissure was hypertrophic. We speculated that the developmental disturbance of the corpus callosum might be related to the cause of the psychiatric disorders in the present cases.

The cytoskeleton, composed of microtubules, intermediate filaments and actin filaments is vital for various cellular functions, particularly within the nervous system, where microtubules play a key role in intracellular transport, cell morphology, and synaptic plasticity. Tubulin-specific chaperones, including tubulin folding cofactors (TBCA, TBCB, TBCC, TBCD, TBCE), assist in the proper formation of α/β-tubulin heterodimers, essential for microtubule stability. Pathogenic variants in these chaperone-encoding genes, especially TBCD, have been linked to Progressive Encephalopathy with Brain Atrophy and Thin Corpus Callosum (PEBAT, OMIM #604,649), a severe neurodevelopmental disorder.

CSF1R-related leukoencephalopathy (CSF1R-L) and AARS2-related leukoencephalopathy (AARS2-L) were two disease entities sharing similar phenotype and even pathological changes. Although clinically, radiologically, and pathologically similar, they were caused by mutation of two different genes. As the rarity of the two diseases, the differential diagnosis of them was difficult.

Background: The spontaneous fluctuations in functional magnetic resonance imaging (fMRI) signals of the brain's gray matter (GM) have been interpreted as representations of neural activity variations. In previous research, white matter (WM) signals, often considered noise, have also been demonstrated to reflect characteristics of functional activity and interactions among different brain regions. Recently, functional gradients have gained significant attention due to their success in characterizing the functional organization of the whole brain.

The integrity of the frontal segment of the corpus callosum, forceps minor, is particularly susceptible to age-related degradation and has been associated with cognitive outcomes in both healthy and pathological ageing. The predictive relevance of forceps minor integrity in relation to cognitive outcomes following a stroke remains unexplored. Our goal was to evaluate whether the heterogeneity of forceps minor integrity, assessed early after stroke onset (2-6 weeks), contributes to explaining variance in longitudinal outcomes in post-stroke aphasia.

The corpus callosum, a major white matter region central to cognitive function, is vulnerable to aging. Using zeitgeber time (ZT) aligned with environmental light/dark cycles, we investigated temporal gene expression patterns in the corpus callosum of young (5-month-old) and aged (24-month-old) mice using RNA-seq. Comparative analysis revealed more differentially expressed genes across ZT pairs in young mice than aged mice.
