Needle beam two-photon microscopy for simultaneous multiplane neural and vascular imaging in awake mice [PDF]

open access: yesPhotoniX
Comprehensive understanding of brain functions necessitates high-speed imaging of neuronal and vascular dynamics across extensive volumes. Functional neuroimaging investigations with two-photon microscopy are commonly hindered by its limited depth of ...

Insight into pericytes in glioblastoma angiogenesis: In vivo tracking by two‐photon microscopy and proteomic profiling [PDF]

open access: yesAnimal Models and Experimental Medicine
Background Glioblastoma (GBM) is a highly aggressive brain tumor characterized by aberrant angiogenesis and an immunosuppressive microenvironment. Pericytes are aberrantly recruited but their spatiotemporal roles and molecular changes remain unclear ...

Two-Photon Laser Scanning Microscopy

open access: yes, 2008
Since its inception more than 15 years ago, two-photon laser scanning microscopy (2PLSM) has found widespread use in biological and medical research. Two-photon microscopy is based on simultaneous absorption of two photons by fluorophores and subsequent ...

A new phase for two-photon microscopy [PDF]

open access: yesFrontiers in Neuroscience, 2009
Two-photon excitation has enabled remarkable advances in our understanding of the nervous system. Its three-dimensional resolution, superior depth penetration, and minimal phototoxicity for out-of-focus portions of the sample have made it the technique of choice for an impressive array of applications.

Two-photon laser scanning fluorescence microscopy using photonic crystal fibre [PDF]

open access: yes, 2004
We report the application of a simple yet powerful modular pulse compression system, based on photonic crystal fibres which improves upon incumbent twophoton laser scanning fluorescence microscopy techniques.

Cellular correlates of gray matter volume changes in magnetic resonance morphometry identified by two-photon microscopy

open access: yesScientific Reports, 2021
Magnetic resonance imaging (MRI) of the brain combined with voxel-based morphometry (VBM) revealed changes in gray matter volume (GMV) in various disorders. However, the cellular basis of GMV changes has remained largely unclear. We correlated changes in

Two-Photon Imaging to Unravel the Pathomechanisms Associated with Epileptic Seizures: A Review

open access: yesApplied Sciences, 2021
Despite extensive research, the exact pathomechanisms associated with epileptic seizure formation and propagation have not been elucidated completely. Two-photon imaging (2PI) is a fluorescence-based microscopy technique that, over the years, has been ...

Planar Airy beam light-sheet for two-photon microscopy [PDF]

open access: yesBiomedical Optics Express, 2020
We demonstrate the first planar Airy light-sheet microscope. Fluorescence light-sheet microscopy has become the method of choice to study large biological samples with cellular or sub-cellular resolution. The propagation-invariant Airy beam enables a ten-
