19 Jun 2006 | Subject: | Statistical Mechanics | 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. | Source: | arXiv, cond-mat/0606496 | Services: | Forum | Review | PDF | Favorites |
