In a recent As I See It, Yoshioka (2008, Mar Ecol Prog Ser 368:309–310) stated that the term Bray-Curtis should only be used for doubly-standardised data, and when data counts are used to calculate similarity, the term Czekanowski is correct; by using the wrong name, it is claimed, marine ecologists demonstrate a lack of knowledge and introduce confusion. This needs to be rectified. It is incor...

The interplay of time-delayed feedback and temporally correlated coloured noise in a single and two coupled excitable systems is studied in the framework of the FitzHugh-Nagumo (FHN) model. By using coloured noise instead of white noise, the noise correlation time is introduced as an additional time scale. We show that in a single FHN system the major time scale of oscillations is strongly infl...

In this paper, we revisit the issue of the utility of the FitzHugh-Nagumo (FHN) model for capturing neuron firing behaviors. It has been noted (e.g., see [6]) that the FHN model cannot exhibit certain interesting firing behaviors such as bursting. We illustrate that, by allowing time-varying parameters for the FHN model, one could overcome such limitations while still retaining the low order co...
