    • Abstract:
      The effect of a high-frequency signal on the FitzHugh-Nagumo excitable model is analyzed. We show that the firing rate is diminished as the ratio of the high-frequency amplitude to its frequency is increased. Moreover, it is demonstrated that the excitable character of the system, and consequently the firing activity, is suppressed for ratios above a given threshold value. In addition, we show that the vibrational resonance phenomenon turns up for sufficiently large noise strength values. ; The Juan de la Cierva program of the Ministerio de Ciencia y Tecnología , the Dirección General de Enseñanza Superior of Spain by Project No. BFM2002-03822 , the Junta de Andalucia , and the Universidad Rey Juan Carlos under Project No. PPR-2004-38.
