Oscillatory QIF responses to jumps in mean input current and noise.

The top panels are QIF firing rates in response to jumps in mean input current and the bottom panels are QIF firing rates in response to jumps in noise. For panels (A) and (C), τ_s = 0 ms. For panels (B) and (D), τ_s = 5 ms. The variance in synaptic component was 4000 mV²-ms for (A) and (B), or 2250 mV²-ms prior to the step in noise for (C) and (D).
