We combined experiments and computational modeling to investigate the effects of sympathetic nerve stimulation on mouse and rabbit hearts.
Study Purpose: We performed physiological sympathetic nerve stimulation while optically mapping cardiac action potentials and intracellular calcium transients in innervated mouse and rabbit hearts.
Data Collection: This package includes experimental optical mapping data (derived from https://doi.org/10.1113/JP278016) and mathematical models of mouse and rabbit ventricular myocytes.
Primary Conclusion: We found notable differences in spatio-temporal repolarization dynamics and used species-specific computational models to investigate the underlying mechanisms.
Curator's Notes
Experimental Design: A computation model. Experimental data derived from https://doi.org/10.1113/JP278016
Completeness: This dataset is complete.
Subjects & Samples: N/A (computational modeling dataset)
Primary vs derivative data: There is no primary data, only a derivative folder containing experimental optical mapping data summarized in the multi spreadsheet excel table.
Code Availability: Matlab codes (and instructions) for simulating the model of mouse and rabbit ventricular myocytealong with simulations are contained in the code folder. Each code folder contains detailed instructions on how to use the code and reproduce simulations. Model codes are also available for download at: https://somapp.ucdmc.ucdavis.edu/Pharmacology/bers/, or http://elegrandi.wixsite.com/grandilab/downloads.
