We consider a firing-rate model, that may be used to model EEG, justifying its use by comparison with a conductance-based refractory density population model and a set of individual neurons. It is shown that stimulation of the system by applying a step-wise current, results in a sharp peak in the population activity that can be reproduced by the EEG-model. In addition the steady-state activity may also be reproduced. Similar comparisons are obtained for stimulation via oscillatory inputs
