We study the synchronized/unsynchronized transition as a function of the noise intensity which appears in a system of globally coupled FitzHugh–Nagumo units under the effect of white noise. By the use of the proper definition of an order parameter, we obtain numerically the phase diagram as a function of the noise intensity and coupling constant.
