Calcium accumulation into a volume of area*depth next to membrane with a decay to resting level. From hemond et al. (2008), model no. 101629, with changes including modified tau = 40 instead of 100 (line 37). Animal model taken from chen (2005) which is used to constrain model. Channel kinetics from previous study on hippocampal pyramidal neuron (hemond et al. 2008)
