They are involved in various essential neuronal functions, with specific miRNAs preferentially expressed in different cell types within the nervous system. Notably, certain miRNAs are found at higher levels in the brain and spinal cord compared to other tissues, suggesting they may have specialized functions in the CNS. miRNAs associated with long-term neurodegenerative changes could serve as valuable tools for early treatment decisions and disease monitoring. The significance of miRNAs such as miR-320, miR-146 and miR-29 in the early diagnosis of neurodegenerative disorders becomes evident, especially considering that many neurological and physical symptoms manifest only after substantial degeneration of specific neurons. Interestingly, serum miRNA levels such as miR-92 and miR-486 may correlate with various MRI parameters in multiple sclerosis. Targeting miRNAs using antisense strategies, such as antisense miR-146 and miR-485, may provide advantages over targeting mRNAs, as a single anti-miRNA can regulate multiple disease-related genes. In the future, anti-miRNA-based therapeutic approaches could be integrated into the clinical management of neurological diseases. Certain miRNAs, including miR-223, miR-106, miR-181, and miR-146, contribute to the pathogenesis of various neurodegenerative diseases and thus warrant greater attention. This knowledge could pave the way for the identification of new diagnostic, prognostic, and theranostic biomarkers, and potentially guiding the development of RNA-based therapeutic strategies.

Early diagnosis and accurate segmentation are critical for effective treatment planning. Due to its high soft tissue contrast, Magnetic Resonance Imaging (MRI) is commonly used for detecting these occlusions such as ischemic stroke. However, challenges such as low contrast, noise, and heterogeneous lesion structures in MRI images complicate manual segmentation and often lead to misinterpretations. As a result, deep learning-based Computer-Aided Diagnosis (CAD) systems are essential for faster and more accurate diagnosis and treatment methods, although they can sometimes face challenges such as high computational costs and difficulties in segmenting small or irregular lesions. This study proposes a novel U-Net architecture enhanced with ConvNeXtV2 blocks and GRN-based Multi-Layer Perceptrons (MLP) to address these challenges in cerebral vascular occlusion segmentation. This is the first application of ConvNeXtV2 in this domain. The proposed model significantly improves segmentation accuracy, even in low-contrast regions, while maintaining high computational efficiency, which is crucial for real-world clinical applications. To reduce false positives and improve overall accuracy, small lesions (≤5 pixels) were removed in the preprocessing step with the support of expert clinicians. Experimental results on the ISLES 2022 dataset showed superior performance with an Intersection over Union (IoU) of 0.8015 and a Dice coefficient of 0.8894.

When injected into the IGL alone, orexin produced small and inconsistent phase shifts that overall did not differ significantly from vehicle control. The glutamate agonist NMDA caused non-photic-like phase shifts when applied to the IGL. While a cocktail of both carbachol and NMDA inhibited each other’s phase shifting effects, a cocktail that included orexin, carbachol and NMDA reversed this inhibition and yielded the largest phase shifts of all.
