Bursting in cerebellar stellate cells induced by pharmacological agents: Non-sequential spike adding
Fig 9
Color-map of the various regimes of behavior associated with the full system (1) in the (gK(Ca), gA)-plane, when gHVA = 0.249 μS.cm−2.
The square-wave bursting regime, labeled SW, is color-coded based on the number of spikes in its corresponding BPOs, calibrated according to the color-bar to the right. For further clarity, the number of spikes in various regions of SW are displayed. The number of spikes increases as gK(Ca) decreases such that for small values of gK(Ca), the system transitions to tonic firing (labeled T). The yellow and red curves are two-parameter continuation of the period-doubling and saddle-node bifurcations of periodic orbits detected in Fig 8A, respectively.
