The recently developed deep learning registration methods have concentrated on improving the loss function and refining model architectures (Fan et al. 2019; Yang et al. 2017; Zhang 2018); however, for more complex mesoscopic optical imaging datasets, applying such inherent strategies are not particularly effective.

Imaging based on blood flow dynamics is widely used to study sensory processing. Here we investigated the extent to which local neuronal and capillary responses (two-photon microscopy) are correlated to mesoscopic responses detected with fast ultrasound (fUS) and BOLD-fMRI. Using a specialized chronic olfactory bulb preparation, we report that High-resolution scanning tunneling microscopy imaging of mesoscopic graphene sheets on an insulating surface Elena Stolyarova , Kwang Taeg Rim , Sunmin Ryu , Janina Maultzsch , Philip Kim , Louis E. Brus , Tony F. Heinz , Mark S. Hybertsen , and George W. Flynn 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). 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. 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 ). mesoscopic imaging approaches, will be discussed regarding their contribution toward a better understanding of pancreatic anatomy both in normal conditions and in the diabetic setting.
We define mesoscopic imaging as a widefield, single-photon, fluores-cence-based modality that can monitor activity across multiple millimeters of tissue at video frame rate. This approach enables Optical imaging has revolutionized our ability to monitor brain activity, spanning spatial scales from synapses to cells to circuits. 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.
