caMonoExp {CalciOMatic} | R Documentation |
The function caMonoExp
returns a vector of intracellular
calcium concentration ([Ca^2+]) vs time values t
. A dCa
jump
occurs at tOn
, followed by a monoexponential return to baseline
value Ca0
, with time constant tau
.
caMonoExp(t = 1, tOn = 1, Ca0 = 0.05, dCa = 0.1, tau = 3)
t |
a vector of time values at which [Ca^2+] is computed (in s) |
tOn |
the time of the [Ca^2+] jump (in s) |
Ca0 |
the baseline [Ca^2+] (in muM) |
dCa |
the [Ca^2+] jump occuring at tOn (in muM) |
tau |
the time constant of the [Ca^2+] monoexponential return to baseline (in s) |
A vector containing the [Ca^2+] values. The vector has the two following attributes:
Time |
a copy of argument t |
tOn |
a copy of argument tOn |

## Simulate a monoexponential calcium transient Ca <- caMonoExp(t = seq(0,10,0.1), tOn = 2, Ca0 = 0.25, dCa = 1, tau = 2) ## Plot the calcium transient vs. time plot(attr(Ca,"Time"),Ca,type="l") ## Add a vertical dashed line at tOn abline(v = attr(Ca,"tOn"), lty = 2)
