notes.txt: some odds and ends:
To graph long time scale trajectory of the activity dependent
coefficients, follow these steps:
1) start the model.
2) Close the voltage graph and hide the multipanel conductance graphs.
(Graphing while running a simulation in NEURON takes longer than
displaying the graph at the end. The voltage trajectory will be
made invalid by the low number of points plotted per millisecond on
this run). Change the Points plotted/ms to 1/60000 (one point
every minute of simulation time) and the Scrn update interval to 1
second. Change tstop to 1e6
3) press Init & Run. Wait till it finishes.
4) click on Window > nrniv on the NEURON Main Menu to redisplay the
(previously hidden) conductances graph.
5) Near the bottom of the window titled "Figure 3 Liu, Golowash,
Marder, Abbott 1998" click the button labeled "View = plot on fig3
bottom graphs". Click on the "fig 3 conductance labels" button
above that. View the long trajectories in the nrniv window.

Computation of the relative Ca shell size between Davison (Bhalla and
Bower) and Liu et al. 1998. From the way that Davison et al. calculate
with B:
cai'=B * ica  (caicainf)/tau
there is an implicit factor of tau e.g.
B= b_D/tau_D = 5.18e2
In Davison tau = tau_D (to keep straight from Liu et al.)=10
In Liu et al. tau=tau_L=20 and B=b_L/tau_L=.94/20=4.7e2
Therefore the b's are
b_D=.518
b_L=.94
since b=(1e4)/(2*FARADAY*depth) i.e. inversely proportional to depth
b_L/b_D = .94/.518 = 1.8146718
depth_D/depth_L = 1.8147
depth_L/depth_D = .55
Davison sets depth to 1 um which implies the Liu et al. depth is
0.55 um.
