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.

Mesoscopic imaging techniques have been developed for medical and clinical research, such as drug delivery, cancer diagnosis, etc. Especially when combined with novel nanoparticles and organic dyes in the near-infrared spectral regime, the mesoscopic imaging can probe deeper parts of the animal body. 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. The CM2features a compact lightweight design that integrates a microlens array for imaging and a light-emitting diode array for excitation.

In particular, optical projection tomography (OPT) and light sheet ﬂuorescence microscopy (LSFM) imaging of the pancreas and their associated tissue 2019-11-04 · Our multi-scale approach involves a microscope with an orthogonal axis design where the mesoscopic objective is oriented above the brain and the two-photon objective is oriented horizontally, with imaging performed through a microprism. We also introduce a viral transduction method for robust and widespread gene delivery in the mouse brain. 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.

Mesoscopic Fluorescence Molecular Tomography (MFMT) is a novel optical imaging modality that reveals the 3D distribution of fluorescent probes at depths of a

These materials range in size between the nanoscale for a quantity of atoms (such as a molecule) and of materials measuring micrometres. The lower limit can also be defined as being the size of individual atoms. 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 Recording brain activity at the mesoscopic scale has thus a strong potential to unveil many new fundamental neuronal operations and innovative clinical applications.

mesoscopic ﬂuorescence imaging, a rapidly developing approach that directly addresses this challenge. 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

Mesoscopic imaging techniques have been developed for medical and clinical research, such as drug delivery, cancer diagnosis, etc.

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.

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.

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, and many others. In this review, we focus on an emerging depth-resolved optical mesoscopic imaging technique, termed laminar optical tomography (LOT) or mesoscopic fluorescence molecular tomography (MFMT), which enables longitudinal imaging of cellular distribution in thick tissue engineering constructs at depths of a few millimeters and with relatively high resolution. Our group is exploring physical phenomena occurring at and between various spatial and time scales in radiotherapy imaging and treatment of cancer.
