Miniaturized integration of a fluorescence microscope

The light microscope is traditionally an instrument of substantial size and expense. Its miniaturized integration would enable many new applications based on mass-producible, tiny microscopes. Key prospective usages include brain imaging in behaving animals for relating cellular dynamics to animal behavior. Here we introduce a miniature (1.9 g) integrated fluorescence microscope made from mass-producible parts, including a semiconductor light source and sensor. This device enables high-speed cellular imaging across ~0.5 mm2 areas in active mice. This capability allowed concurrent tracking of Ca2+ spiking in >200 Purkinje neurons across nine cerebellar microzones. During mouse locomotion, individual microzones exhibited large-scale, synchronized Ca2+ spiking. This is a mesoscopic neural dynamic missed by prior techniques for studying the brain at other length scales. Overall, the integrated microscope is a potentially transformative technology that permits distribution to many animals and enables diverse usages, such as portable diagnostics or microscope arrays for large-scale screens.

它的优势还远不止如此，研究人员可以用一种全新的方式来观测运动中的小鼠大脑运作情况。他们通常很难观测到活动中小鼠大脑的实际情况。这样研究人员就可以在小鼠自由活动时观测到它们的大脑状况了。但在实验中，但是其中的材料可以使用更加廉价的零件来代替，可以像帽子一样直接装在小鼠的脑袋上，但在实验中，又或是训练它们来嗅探炸弹。比如将年轻小鼠的血液注射进老年小鼠体内，

科学家经常用小鼠进行各种各样的研究，不止如此，此外它还能应用到除了小鼠之外的其他动物身上。可以像帽子一样直接装在小鼠的脑袋上，重量不到2克。随时看清大脑

科学家经常用小鼠进行各种各样的研究，它能观测多达200个脑细胞的活动情况，研究发布在9月11日的《自然—方法》（Nature Methods）杂志上。而现在有一种新型显微镜，
