Summary[edit]

Description
English: A representative example of simultaneous recording of 2D intracellular Ca2+ dynamics (Fluo-4 signals, top panel) by a high-speed Hamamatsu C9100-12 CCD camera and action potentials (bottom panel) by perforated patch clamp in an isolated single rabbit SA node cell. Middle panel shows simultaneous dynamics of the total Ca2+ signal (calculated total Fluo-4 fluorescence). The movie shows 14 pacemaker cycles (about 5 s total duration) recorded at a physiological temperature of 35°C. The movie is played about 4.6 times slower vs. real time recording. Images have size 512×160 pixels (or 128×40 µm). The cell shown in this movie is also presented in Figure 4.

This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it.
