# FOR the case of time dependent state variable such as membrane potential the following definition is applied.
# var v: mV {init: v_init, pub: out};
# ode(v, time) = - I_tot;
#
# FOR the case of step-wise changes in state variable such as membrane potential the following definition is applied
# var v: mV {pub: out};
# v = sel
# case (time <= time_clamp_sta) and (v_var == 0{dimensionless}):
# v_hold;
# case (time > time_clamp_sta) and (time <= time_clamp_end) and (v_var == 0{dimensionless}):
# v_clamp;
# otherwise:
# v_hold;
# endsel;
