Forced oscillations in islets. a Example of glucose-stimulated [Ca2+]i results from a forced oscillations experiment containing N = 9 islets over a period of 55 min. The y-axis is labeled as the ratio of excitation and emission fluorescence (340/380 nm) to indicate changes in islet [Ca2+]i throughout the experiment. b Time averaged results of the forced oscillation experiment. The average florescence ratio of the islets was calculated and time averaged in one minute intervals to mirror the trypan blue timed studies
