Journal Article
Johnstone, R. H., Chang, E. T., Bardenet, R., de Boer, T. P., Gavaghan, D. J., Pathmanathan, P., …Mirams, G. R. (2016). Uncertainty and variability in models of the cardiac action potential: Can we build trustworthy models?. Journal of Molecular and Cellular Cardiology, 96, 49-62. https://doi.org/10.1016/j.yjmcc.2015.11.018

Cardiac electrophysiology models have been developed for over 50 years, and now include detailed descriptions of individual ion currents and sub-cellular calcium handling. It is commonly accepted that there are many uncertainties in these systems, wi...

Mathematical Modelling of Heart Rate Changes in the Mouse (2015)
Report
Christie, M., Nandi, M., Borg, Y., Carapella, V., Mirams, G., Aston, P., …Chakrabarti, B. Mathematical Modelling of Heart Rate Changes in the Mouse. NC3Rs

The CVS is composed of numerous interacting and dynamically regulated physiological subsystems which each generate measurable periodic components such that the CVS can itself be presented as a system of weakly coupled oscillators. The interactions be... Read More about Mathematical Modelling of Heart Rate Changes in the Mouse.
