// dend_shaft_bAP_functions.hoc
/*
Contains the create and write vector functions and associated
declarations modified from param3.hoc (which calculated simulations
for changes in the 3 parameters mshift (in ca current), ECl, gbar_ca)
(Modified from param3 documentation:)
For the following send traces
I) control Ca traces (protocol bAP)
II) Ca with inhib (bAPdendinhib)
III) calculate dCa for control and inhibited and their ratio for each
compartment:
dCa(inhibited)/dCa(control) = ([Ca2+]peak,inh - B)/([Ca2+]peak,ctrl - B)
calculated from I), II):
dCa_ratio.txt
IV) record also the dCa(inhibited), dCa(control) values separately
dCa_inhib.txt
dCa_ctrl.txt
The calcium and voltage trace files are stored in "proto_dir/file"
where protocols directory proto_dir can be upto
inhibspine, 1xinhibdend, 10xinhibdend, bAP, bAPinhibspine, bAP10xinhibdend,
bAP1xinhibdend
and files can be as many as spine0_ca, spine1_ca, spine2_ca, dend_ca, spine0_v,
spine1_v, spine2, dend_v
however here unlike in FiveConditions.hoc, the protocols and files are
limited to X/bAP X/bAPspineinhib and spine1_ca, spine0_ca where spine1
is the middle spine head, and spine0 is the proximal spine head
(receives a smaller bAP typically because of the slight increase in
bAP amplitude as a function of distance along the dendrite.
