Paper Abstract

High resolution fluorescence imaging in intact tissues faces special challenges posed by scattering of excitation and fluorescence light and the need to avoid photodynamic damage. Significant improvements over conventional widefield and confocal imaging are provided when two-photon excitation is used. Applications to the functional imaging of the calcium dynamics in synaptic spines, small invertebrate neurites, and auditory hair cells are shown. Two-photon absorption induced photolysis can also be used for scanning photochemical microscopy and for high resolution measurements of diffusional coupling between cellular compartments.
