Patterns of calcium oscillations in a network of 50 GnRH neurons. Ten different colors have been used; each color is used to represent the activity of 5 individual cells. a represents the 50 individual Ca j patterns along a 180 minute period. Note that synchronization occurred at minute 17, 78, and 139, which gives 61 minute intervals between synchronizations. The height of the synchronized peaks is larger than the height of normal peaks, and the postexcitatory suppressions are seen right after each synchronization episode. b displays a magnified view of the asynchronous phase occurring between successive episodes of synchronization. The Ca j patterns display variability in IPI and height of the peaks between cells. Depending on the phases of each cell when the synchronization is triggered, the calcium peaks may be more or less tightly synchronized as emphasized in c and d
