Currents responsible for the duration of an UP state. (A) IKNa current and (B) IKCa current, for four different values of the depression factor fD (figure shows the case where only excitatory synaptic connections are depressed). IKNa current increases slower while IKCa decreases slower during burst as a function of the level of synaptic depression, which tends to lengthen the duration of UP states.
