 To determine their relationship, we firstly determine the network instabilities that give rise to oscillations, and the set of false bifurcationsthat occur beyond this onset.

 To determine their relationship, we firstly determine the network instabilities that give rise to oscillations, and the so-called `false bifurcations' (for which a significant qualitative change in the orbit is observed, without a change of stability) occurring beyond this onset.
