目前,静息状态功能磁共振成像(RsfMRI)越来越多地应用于人类神经病理研究。本研究的目的是在小鼠身上实施rsfMRI,这是一种拥有最广泛种类的神经疾病模型的物种。此外,通过使用类似的麻醉、扫描和分析方案获取rsfMRI数据,我们能够在大鼠和小鼠身上比较在这两个物种中获得的结果。RsfMRI的结果对于大鼠和小鼠是不同的,并且在很大程度上取决于独立成分分析(ICA)中应用的成分数量。最重要的区别是,与双侧大鼠皮质网络相比,小鼠静息状态数据出现了单侧皮质成分。此外,与大鼠相比,ICA分析需要更多的成分来分离小鼠的不同皮质区域。
At present, resting state functional MRI (rsfMRI) is increasingly used in human neuropathological research. The present study aims at implementing rsfMRI in mice, a species that holds the widest variety of neurological disease models. Moreover, by acquiring rsfMRI data with a comparable protocol for anesthesia, scanning and analysis, in both rats and mice we were able to compare findings obtained in both species. The outcome of rsfMRI is different for rats and mice and depends strongly on the applied number of components in the Independent Component Analysis (ICA). The most important difference was the appearance of unilateral cortical components for the mouse resting state data compared to bilateral rat cortical networks. Furthermore, a higher number of components was needed for the ICA analysis to separate different cortical regions in mice as compared to rats.
