Calcium imaging of gut activity
Neurogastroenterology & Motility, 2004AbstractThe major cell types regulating gut motility include enteric neurones, interstitial cells of Cajal (ICC) and their effector smooth muscle cells. These cells are arranged conveniently in nested layers through the gut wall. Our knowledge of how many of these cells in each layer are integrated to produce the various patterns of motility is largely

Calcium Imaging in Mouse Superior Colliculus
Journal of Visualized Experiments, 2023The superior colliculus (SC), an evolutionarily conserved midbrain structure in all vertebrates, is the most sophisticated visual center before the emergence of the cerebral cortex. It receives direct inputs from ~30 types of retinal ganglion cells (RGCs), with each encoding a specific visual feature.

We review herein the following questions related to Ca2+ imaging: what are the key elements to consider in a Ca2+ imaging system? What are the limits of such systems? What are the main artifacts and to what specific applications are a Ca2+ imaging systems best adapted?

Calcium Imaging of Non-adherent Cells
2023Live-cell imaging can reveal dynamic and multimodal cell signaling by monitoring calcium flux. Spatiotemporal changes in Ca2+ concentrations instigate specific downstream processes and by categorizing these events, we can examine the language cells use to communicate both to themselves and with each other.

As our understanding of the biological sciences expands, the boundaries between traditional disciplines tend to blur at the edges. Physiologists and pharmacologists, for instance, now need to embrace techniques that until recently were the strict preserves of biochemists and molecular biologists.

Ex vivo calcium imaging in Drosophila opens an expansive amount of research avenues for the study of live signal propagation through complex tissue. Here, we describe how to isolate Drosophila organs of interest, like the developing wing imaginal disc and larval brain, culture them for extended periods, up to 10 h, and how to image the calcium dynamics

Dopaminergic Regulation of Dendritic Calcium: Fast Multisite Calcium Imaging
2012Optimal dopamine tone is required for the normal cortical function; however it is still unclear how cortical-dopamine-release affects information processing in individual cortical neurons. Thousands of glutamatergic inputs impinge onto elaborate dendritic trees of neocortical pyramidal neurons.

High-Resolution Calcium Imaging Method for Local Calcium Signaling
2019All eukaryotic cells respond to extracellular signals in a physiologically meaningful way. For multicellular organisms, physiologically relevant cooperation is only possible, if cell-cell communication works properly. Here, the extracellular signals must be translated into intracellular signals that ultimately result in cellular responses. This process

Calcium Imaging in the Zebrafish
2012The zebrafish (Danio rerio) has emerged as a widely used model system during the last four decades. The fact that the zebrafish larva is transparent enables sophisticated in vivo imaging, including calcium imaging of intracellular transients in many different tissues. While being a vertebrate, the reduced complexity of its nervous system and small size
