“…Fluorescent calcium imaging is a common approach to capturing the dynamics of neuron signaling, as the AP of an excited neuron triggers the influx of calcium ions through various channels 67 . Specifically, cultured rat hippocampal neurons were labeled with Fluo-4 calcium dye and subsequently stimulated using a lab-built electronic probe 76 (detailed in Supplementary Section 5.1), with each stimulation producing an AP-evoked calcium transient within the neurons (Fig. 1a and Supplementary Movie 6).…”

“…4e and Supplementary Movie 10). Such a breadth of signaling variety results from an intricate combination of underlying variables 66 , including the field stimulation that can excite various parts of the neuron 76 , natural biological complexity involving the relative concentration and location of membrane voltage-gated calcium channels 77,78 , and calcium kinetics 79 . To the best of our knowledge, this study presents the demonstration of the direct visualization of AP-driven calcium wave propagation matching framerates previously achieved only using sub-frame interpolation [73][74][75] .…”
