Journal ArticleDOI
Scanning fiber endoscopy with highly flexible, 1 mm catheterscopes for wide-field, full-color imaging
TL;DR: A new and versatile scanning fiber‐imaging technology is reviewed and its implementation for ultrathin and flexible endoscopy is described, providing new options for in vivo biological research of subsurface tissue and high resolution fluorescence imaging.
Journal ArticleDOI
Ultra-compact fiber-optic two-photon microscope for functional fluorescence imaging in vivo
TL;DR: A small, lightweight two-photon fiberscope is presented and functional imaging of calcium signals in Purkinje cell dendrites in the cerebellum of anesthetized rats is demonstrated.
Journal ArticleDOI
Simultaneous BOLD fMRI and fiber-optic calcium recording in rat neocortex.

TL;DR: Combining fMRI with fiber-optic recordings of fluorescent calcium indicator signals to investigate the relationship to underlying neural activity in rat somatosensory cortex highlights the complexity of fMRI BOLD signals, involving both neuronal and glial activity.
Journal ArticleDOI
Miniaturized selective plane illumination microscopy for high-contrast in vivo fluorescence imaging
TL;DR: Images of fluorescent beads and neurons in mouse neocortex exhibited superior axial resolution and contrast in the miniSPIM-mode compared to images recorded in epi-illumination mode, and may enable novel in vivo imaging approaches.
Journal ArticleDOI
Enhanced fluorescence signal in nonlinear microscopy through supplementary fiber-optic light collection
TL;DR: This work presents a ring of large-core optical fibers for epi-collection of fluorescence photons that are not transmitted through the objective and thus normally wasted, and recommends SUFICS as a generally applicable, effective add-on to nonlinear microscopes for enhancing fluorescence signals.
