Why ACRO:

MEA Verified Spontaneous Network Burst Activity

This data set highlights the intrinsic activity of our Human iPSC-Derived Dopamine Neurons (Cat. No. CIPC-DDC001) cultured on an MEA plate. The neurons exhibit robust spontaneous firing, as visualized in the accompanying heatmap video. The raster plot clearly shows regular network burst firing patterns, indicative of well-coordinated neuronal activity. The photo of the neurons on the MEA plate further confirms the successful culture and network formation, making this data a powerful demonstration of their functional connectivity and suitability for neurophysiological studies.

MEA Verified Haloperidol-Induced Modulation of Neuronal Firing

This data set demonstrates the dose-dependent effects of Haloperidol on neuronal firing. Raster plots and associated firing parameters (for Weighted Mean Firing Rate, Number of Bursts, Burst Duration, Burst Frequency, and Number of Network Bursts, n = 2) are presented for varying Haloperidol concentrations. At 0.1 μM, the firing activity is enhanced, while at 1 μM, the activity diminishes. At 10 μM, the firing is nearly abolished. These results are consistent with findings from Yokoi et al. (2019), where Haloperidol is known to inhibit D2 receptors at low doses and 5-HT2 receptors at high doses (Tyler et al., 2017). This confirms that the relevant receptors in our Human iPSC-Derived Dopamine Neurons (Cat. No. CIPC-DDC001) are functioning normally, underscoring their utility in drug screening and neurotoxicity studies.
