- eK = -77
- eL = -54.4
Voltage dependent coefficient functions:
am <- function(v) { 0.1 * (v + 40) / (1 - exp( -(v + 40) / 10)) }
bm <- function(v) { 4 * exp( -(v + 65) / 18) }
ah <- function(v) { 0.07 * exp( -(v + 65) / 20) }
bh <- function(v) { 1 / (1 +exp( -(v + 35) / 10)) }
an <- function(v) { 0.01 * (v + 55) / (1 - exp( -(v + 55) / 10)) }
bn <- function(v) { 0.125 * exp( -(v + 65) / 80) }Model parameters:
- C - membrane capacitance per unit area
