Microstimulation in a spiking neural network model of the midbrain superior colliculus

Bursting mechanism of the AdEx neuron model.
Phase plots of V(t) vs. q(t) of the neural dynamics of the same three neurons of Fig 1. Biophysical parameters of the neurons were selected for their bursting responses to a ramp stimulus, with varying current amplitude and durations (traces are marked in Fig 1); the order of spike occurences is denoted next to the traces in the spike initiation zone): A: a burst with 5 spikes (x); B: two burst cycles with 6 and 5 spikes (o); C: a burst cycle with more than 13 spikes (+).
