All parameters for the somatic compartment, with the exception of the adaptation
conductance and the coupling conductance between somatic and dendritic
compartments, are given by the standard model of Connor
et al. (1977). The evolution of the voltage in the somatic compartment
is given by the differential equation:
The peak conductances, measured per membrane area, are
The variable adaptation conductance
depends on the spiking frequency through a calcium accumulation mechanism,
which has been calibrated to yield a mean adaptation conductance of .(Further
details on the adaptation conductance in the Adaptation
subsection.)
The reversal potentials are set to
mV,
mV, and
mV. Since the A-current is a potassium current, the associated reversal
potential should be .
However, Connor
et al. (1977) redefined the reversal potential associated with
this conductance, setting it to
mV.
