光学相干断层扫描(OCT)允许生物组织的精细结构的无标记、微米级3D成像,具有显著的深度和大视场。在这里,我们介绍了一种新的基于OCT的神经成像设置,伴随着一个特征分割算法,它可以快速,准确,高分辨率的700 μm深度的小鼠大脑皮层在体内成像。使用商业OCT设备,我们展示了通过皮质柱的微结构元素的3D重建。我们的系统对体内微米级分辨率的结构和细胞变化敏感,例如来自损伤或疾病的变化。因此,它可以作为一种工具来可视化和量化时空脑弹性模式。这个高度变革性和多功能的平台可以通过量化脑细胞体的密度、体积和与最近细胞的平均距离等特征来准确研究脑细胞结构的变化。因此,它可能有助于纵向研究的微观结构组织的变化,在老化,损伤,或疾病的活啮齿动物的大脑。
Optical coherence tomography (OCT) allows label-free, micron-scale 3D imaging of biological tissues’ fine structures with significant depth and large field-of-view. Here we introduce a novel OCT-based neuroimaging setting, accompanied by a feature segmentation algorithm, which enables rapid, accurate, and high-resolution in vivo imaging of 700 μm depth across the mouse cortex. Using a commercial OCT device, we demonstrate 3D reconstruction of microarchitectural elements through a cortical column. Our system is sensitive to structural and cellular changes at micron-scale resolution in vivo, such as those from injury or disease. Therefore, it can serve as a tool to visualize and quantify spatiotemporal brain elasticity patterns. This highly transformative and versatile platform allows accurate investigation of brain cellular architectural changes by quantifying features such as brain cell bodies’ density, volume, and average distance to the nearest cell. Hence, it may assist in longitudinal studies of microstructural tissue alteration in aging, injury, or disease in a living rodent brain.
