Connected networks are a fundamental structure of neurobiology. Understanding these networks will help us elucidate the neural mechanisms of computation. Mathematically speaking these networks are “graphs”—structures containing objects that are connected.

A Novel Method to Quantify Calcium Response Pattern and Oscillation Using Fura2 and Acridine Orange
To study calcium imaging data of cell populations that have various response patterns in peak amplitude and frequency of calcium oscillation in response to stimulation, comprehensive characterization based on statistical analysis of each response is ...

Fluorescent sensors for imaging of interstitial calcium [PDF]
Abstract Calcium in interstitial fluids is central to systemic physiology and a crucial ion pool for entry into cells through numerous plasma membrane channels. Its study has been limited by the scarcity of methods that allow monitoring in tight inter-cell spaces of living tissues.

Calcium Sensor for Photoacoustic Imaging
We introduce a selective and cell-permeable calcium sensor for photoacoustics (CaSPA), a versatile imaging technique that allows for fast volumetric mapping of photoabsorbing molecules with deep tissue penetration. To optimize for Ca2+-dependent photoacoustic signal changes, we synthesized a selective metallochromic sensor with high extinction ...

High-Throughput Platform for Optoacoustic Probing of Genetically Encoded Calcium Ion Indicators
Summary: Functional optoacoustic (OA) imaging assisted with genetically encoded calcium ion indicators (GECIs) holds promise for imaging large-scale neuronal activity at depths and spatiotemporal resolutions not attainable with existing optical ...

Multiphoton Intravital Calcium Imaging [PDF]
AbstractMultiphoton intravital calcium imaging is a powerful technique that enables high‐resolution longitudinal monitoring of cellular and subcellular activity hundreds of microns deep in the living organism. This unit addresses the application of 2‐photon microscopy to imaging of genetically encoded calcium indicators (GECIs) in the mouse brain.

In vivo Calcium Imaging of Evoked Calcium Waves in the Embryonic Cortex [PDF]
The dynamics of intracellular calcium fluxes are instrumental in the proliferation, differentiation, and migration of neuronal cells. Knowledge thus far of the relationship between these calcium changes and physiological processes in the developing brain has derived principally from ex vivo and in vitro experiments.
