Sodium current (INa) model optimization
=========================================
For sodium currents, model parameters were optimized to multiple experimental datasets, \
resulting in dataset-specific parameterization instances of the model. \
For each dataset-specific model, external ion concentrations \
and voltage protocols were set to reflect the corresponding experimental conditions. \
All of the experimental data used to optimize the models were collected in iCell iPSC-CMs. \
This process was used to generate dataset-specific models. \
Three separate experimental iPSC-CM datasets are used for sodium current: \
(A) Ma et al. (B) Jalife Immature, (C) Jalife Mature and (D) Baseline model

A, steady-state inactivation and activation curves. The sodium current model used in \
the baseline whole-cell model is shown in black. Colours represent distinct experimental \
iPSC-CM data from `Ma et al. (2011)`_ and from immature and mature cell preparations \
from the Jalife lab (`Herron et al. 2016`_). C, INa activation (m-gate) time constants. D, INa fast-inactivation (h-gate) \
time constants. E, INa slow-inactivation (j-gate) time constants. j-gate time constant \
parameters for all INa models were optimized to experimental iPSC-CM data from \
the Kurokawa lab (`Li et al. 2017`_).
