Summary: This study found an association between motor impairment in stroke patients and the microstructure of CST originating from M1 pyramidal neurons as well as beta oscillatory activity. The findings suggest a potential link between brain structure and function that may contribute to motor deficits in stroke patients.

Summary: This study identified the transcriptome of spinal motor neurons (MNs) in mice during embryonic and postnatal stages and discovered novel genes and transcription factors related to terminal differentiation. It was found that homeodomain transcription factors, including Hoxc8, played a crucial role in maintaining the expression of terminal differentiation markers in MNs. These findings provide insights into the evolutionary role of Hox in neuronal terminal differentiation.

Summary: This study explored the effects of cyclic mechanical strains applied by acoustic tweezing cytometry (ATC) on human pluripotent stem cells (hPSCs). The results showed that even short-term ATC application could downregulate OCT4 and increase YAP nuclear localization in hPSCs. The displacement of integrin-bound microbubbles was closely correlated with OCT4 downregulation.

Summary: The asymmetry in corticospinal recruitment of spinal motor neurons post-stroke is directly correlated with hand impairments. Spike timing-dependent plasticity can transiently reverse recruitment failures, and this modulation is strongly associated with recruitment asymmetry and impairment severity.

Summary: In this study, it is demonstrated that hydroxyapatite (HAp) nanorods can regulate the neural differentiation of NSCs and lead to the differentiation of NSCs into mature neurons exhibiting well-defined electrophysiological behavior within 5 days. RNA-sequencing data also reveal that the neuroactive ligand-receptor interaction pathway is dominant in the enriched differentiated neuronal population.

Summary: Maintaining lipid homeostasis is crucial for the health and function of neurons, including upper motor neurons (UMNs). UMNs require a stable cell membrane to maintain their unique cytoarchitecture, and lipids play a key role in energy production and the building blocks of biomolecules.

Summary: This study presents a screening platform to systematically elucidate the functional consequences of genetic perturbations in human induced pluripotent stem cell-derived microglia. The researchers identified genes controlling microglia survival, activation, and phagocytosis, as well as disease-associated genes. They also determined regulators of disease-relevant microglial states using single-cell RNA sequencing. The platform has the potential for therapeutic targeting and functional characterization of microglia.

Summary: This study evaluated the neural dynamics of the human grasp network during a repertoire of hand movements using electrocorticography and dimensionality reduction methods. The researchers found that the grasp network represented both finger and grasping movements. While the neural covariance at the distributed network level was preserved, the latent neural dynamics were specific to movement type, indicating compartmentalization into movement-specific submanifolds. This mesoscale organization allows for flexible switching between a repertoire of hand movements.

Summary: The study revealed the crucial role of fgfbp3 in axonal morphogenesis and regeneration of motor neurons in zebrafish, with loss of fgfbp3 leading to defects that can be partially rescued by fgfbp3 mRNA injection and overexpression. Transcriptome sequencing identified drd1b and neurod6a as potential rescuers for motor neuron malformation in fgfbp3 knockout embryos.

Summary: Understanding the development of specialized neural circuits in adult mammals requires studying the changes in neuronal membrane properties and circuits during postnatal maturation. Research on layer V pyramidal neurons in the rat primary motor cortex showed that certain parameters are established at birth, while other properties continue to develop until adulthood. These modifications lead to a decrease in neuronal excitability and an increase in working range, providing more sensitive and accurate responses in young adult neurons.

Summary: Microglia, the tissue-resident macrophages of the central nervous system, have been found to play significant roles in brain development and tissue repair. In addition to their function as immune cells, microglia also modulate the development and functions of neurons and glial cells through interactions.

Summary: The study found that 5hmC undergoes dynamic changes during early human brain development and is associated with AD pathology. AD organoids display cellular and molecular phenotypes similar to those observed in human AD brains. These data suggest a highly coordinated molecular system that may be dysregulated in early developing AD organoids.

Summary: A prominent difference between the brain and spinal cord is their size, with the brain being larger than the spinal cord. The Polycomb Repressor Complex 2 (PRC2) plays a crucial role in promoting the expansion of the anterior central nervous system (CNS) and regulates genes involved in proliferation and immune response. By integrating transcriptomic and epigenetic data, this study reveals the distinct regulatory mechanisms of PRC2 on gene cohorts driving anterior CNS expansion.

Summary: Loss of the neural development-related BAF subunit BAF53a leads to cell cycle arrest and disruption of neurogenesis due to altered chromatin accessibility, which inhibits the binding of specific neural transcription factors and suppresses cell cycle gene expression, highlighting a novel mechanism regulating neural progenitor cell cycle exit in the presence of extrinsic proliferative cues.

Summary: Recent genetic studies suggest that synaptic proteins and ion channels play a crucial role in the development of neurodevelopmental disorders. New evidence indicates that these proteins may have novel functions in immature cells during prenatal development. Advanced techniques, such as single-cell sequencing and human cellular models of disease, have provided insights into the expression and localization of these proteins in the developing brain compared to adults.

Summary: This study compared the reliability and reproducibility of two classification systems (OBC and DJC) for diagnosing trochlear dysplasia. The results showed that OBC had a higher intraobserver reliability score compared to DJC, indicating that it is more reliable. There was no significant difference in the scores between consultants and registrars when evaluating the two classification systems.
