neuron model represent a continuous flow of charge. Considering both ionic currents
and synaptic currents excitation Eq. ( 7.35 ) can be written as

C V D g L .V L V/C s.t/

(7.36)

where g L is the membrane's (ion's channel) conductance, V L is an equilibrium
potential, and s.t/ is the synaptic current input. Spiking is modeled as a threshold
