Whole-Brain Calcium Imaging in Larval Xenopus.

Cold Spring Harbor Protocols, 2020
Sensory systems detect environmental stimuli and transform them into electrical activity patterns interpretable by the central nervous system. En route to higher brain centers, the initial sensory input is successively transformed by interposed secondary

Dopaminergic Regulation of Dendritic Calcium: Fast Multisite Calcium Imaging

2012
Optimal 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

2019
All 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

2012
The 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

Fluorescence lifetime imaging of intracellular calcium

Journal of Fluorescence, 1993
Fluorescence lifetime imaging microscopy (FLIM) is a new methodology for studying the spatial and temporal dynamics of macromolecule, molecules, and ions in living cells. In FLIM image contrast is derived from the mean fluorescence lifetime at each point in a two-dimensional image.

Hybrid Imaging: Calcium Score and Myocardial Perfusion Imaging

Seminars in Nuclear Medicine
Coronary heart disease (CHD) remains the top cause of death due to cardiovascular conditions worldwide, with someone suffering a myocardial infarction every 40 seconds. This highlights the importance of non-invasive imaging technologies like myocardial perfusion imaging (MPI), which are crucial for detecting coronary artery disease (CAD) early, even ...

Coronary artery calcium imaging

2022
Abstract Coronary artery calcium correlates with the extent of coronary atherosclerosis and has been shown to be a strong and independent predictor of long-term cardiovascular. Coronary artery calcium estimates can be obtained from a non-contrast CT scan at low radiation exposure.

Confocal Calcium Imaging

1999
Confocal fluorescence microscopy will, in principle, collect light emitted by only that dye that lies in the plane of focus. Signal from dye in regions of the tissue above and below the plane of focus is rejected. Many of us who study intracellular calcium concentration ([Ca++]i) use monolayers of cells in culture. After loading a calcium indicator dye

Calcium Imaging: A Primer for Mycologists

Fungal Genetics and Biology, 1998
This article aims to encourage more fungal biologists to consider the imaging of cytoplasmic Ca2+ fluxes. Compared to other organisms, for fungi there have been remarkably few attempts to characterize the role of Ca2+ fluxes in signal transduction and general cellular activities, even though other approaches indicate that fungal growth and development ...
