Journal ArticleDOI

Tsai Wen Chen,Trevor J. Wardill,Trevor J. Wardill,Yi Sun,Stefan R. Pulver,Sabine L. Renninger,Amy Baohan,Amy Baohan,Eric R. Schreiter,Rex Kerr,Michael B. Orger,Vivek Jayaraman,Loren L. Looger,Karel Svoboda,Douglas S. Kim +14 more
TL;DR: A family of ultrasensitive protein calcium sensors (GCaMP6) that outperformed other sensors in cultured neurons and in zebrafish, flies and mice in vivo are developed and provide new windows into the organization and dynamics of neural circuits over multiple spatial and temporal scales.
Journal ArticleDOI
Whole-brain functional imaging at cellular resolution using light-sheet microscopy
TL;DR: Light-sheet microscopy is used to record activity from the entire volume of the brain of the larval zebrafish in vivo at 0.8 Hz, capturing more than 80% of all neurons at single-cell resolution, demonstrating how this technique can be used to reveal functionally defined circuits across the brain.
Journal ArticleDOI
Optimization of a GCaMP calcium indicator for neural activity imaging.

TL;DR: GCaMP5 fluorescence provides a more reliable measure of neuronal activity than its predecessor GCaMP3, which allows more sensitive detection of neural activity in vivo and may find widespread applications for cellular imaging in general.
Journal ArticleDOI
An optimized fluorescent probe for visualizing glutamate neurotransmission

TL;DR: An intensity-based glutamate-sensing fluorescent reporter with signal-to-noise ratio and kinetics appropriate for in vivo imaging is described and its utility for visualizing glutamate release by neurons and astrocytes in increasingly intact neurological systems is validated.
Journal ArticleDOI

TL;DR: Red, single-wavelength GECIs, “RCaMPs,” engineered from circular permutation of the thermostable red fluorescent protein mRuby are described and 2-color calcium imaging is demonstrated both within the same cell (registering mitochondrial and somatic [Ca2+]) and between two populations of cells: neurons and astrocytes.
