2020-08-04 · Another recently emerging technique is photoacoustic imaging (PAI) which is capable of detecting absorbing contrast agents deep (~1cm) in scattering tissue with mesoscopic resolution (a few 100µm). PAI is inherently sensitive to chromophore contrast so it is suitable for imaging vascularization and their oxygenation state via intrinsic spectral

Here, we summarize the rapid development and application of mesoscopic imaging, a widefield fluorescence-based approach that balances high spatiotemporal resolution with extraordinarily large fields of view. Mesoscopy typically refers to depths of a few millimeters (1–5 mm) with the resolution in the order of a few microns to tens of microns. Macroscopy then refers to depths beyond 5 mm and resolution ranging from tens of microns to a few hundred of microns, depending on the depth. Herein, we review the fundamental working principles of mesoscopic FLIm, discuss the technical characteristics of current clinical FLIm instrumentation, highlight the most commonly used analytical methods to interpret fluorescence lifetime data and discuss the recent applications of FLIm in surgical oncology and cardiovascular diagnostics. With the mesoscopic FOV volumetric imaging capability, simple sample mounting protocol, and the versatility of changeable FOVs/resolutions, our system will be ready for the future applications requiring in vivo volumetric imaging over a large length scale, such as neural dynamics and vasculature development.

We define mesoscopic imaging as a widefield, single-photon, fluorescence-based modality that can monitor activity across multiple millimeters of tissue at video frame rate. This approach enables recording from the entire dorsal neocortex in awake, behaving rodents.

Mesoscopic Imaging Specialist Montse has always had a genuine interest in bringing to light small details of life through images. After completion of her degree in biology at the Universitat Pompeu Fabra (UPF), she spent two years doing research on inner ear neurogenesis in the Developmental Biology Research Group (UPF). Node Candidate Name: B-Min - Mesoscopic Imaging Node Barcelona The Spanish B-Min – Mesoscopic Imaging Node Candidate in Barcelona provides access to state-of-the-art imaging technologies that span the mesoscopic size range.This includes samples from about half a millimetre up to a couple of centimetres, which may be embryos, embryoids, adult mouse organs, tissue samples, biopsies, plants Although 3D imaging techniques, such as optical projection tomography (OPT) 3 that is based on the attenuation contrast of light 4 have been used for 3D imaging of mouse embryos without labels, few Obviously mesoscopic imaging techniques like OPT and LSFM are not limited to studies of BCM. In particular LSFM techniques, taking advantage of its normally higher resolution, have been recently applied to study aspects of e.g., pancreatic innervation, immune cell infiltration, and proliferation, in various mouse models of diabetes using specific antibody markers for these features ( 34 , 35 ). We demonstrated the depth-resolved capability of 3D mesoscopic imaging by photostimulating the layer 5 neurons in Thy1-ChR2-YFP transgenic mice and further recorded the layer-specific functional projections between primary somatosensory cortex and primary motor cortex in vivo, following single whisker deflection. 2019-11-28 Definition of mesoscopic in the Definitions.net dictionary.

Recording brain activity at the mesoscopic scale has thus a strong potential to unveil many new fundamental neuronal operations and innovative clinical applications. Optical imaging offers a unique opportunity to measure brain activity over a large field-of-view (up to 1cm for flat surfaces) with high spatio-temporal resolutions (20μmx1ms).

The improving technology of UHF fMRI, however, facilitates high-resolution imaging with voxel dimensions smaller than a millimetre, which opens the door for detecting responses at a mesoscopic level, from neuronal subpopulations smaller than was previously possible, such as columns or layers . 2021-03-04 · Obviously mesoscopic imaging techniques like OPT and LSFM are not limited to studies of BCM.
