Abstract:Two-photon microscope is an useful and advanced tool for noninvasive deep fluorescence imaging in the intact brain tissue of living animals. Due to nonlinear two-photon effects, two-photon microscope enables long-term imagingin vivowith deeper detection, higher signal-to-noise ratio and lower photodamage, compared to wide-field and confocal microscopy. Two-photon microscopy can provide high-resolution images to study cellular and subcellular structure and function, including morphology, mobility and intracellular ions of cells. On the other hand, large scale two-photon imaging of cell population reveals the network construction and activity dynamics with single-cell resolution, which makes two-photon microscopy a high throughput tool in system pharmacology. Moreover, two-photon microscopy can offer some precise optical operations, such as photolysis, photoactivation, phototransfection and photodamage. Here, we give an introduction to the principles of two-photon microscopy and itsin vivoapplications in neuroscience and neuropharmacology researches.
