From: Responses of Leaky Integrate-and-Fire Neurons to a Plurality of Stimuli in Their Receptive Fields
Realization of spike trains for different combinations of response kernels and stimuli. Top panels show the three stimulus types; sinusoidal, piecewise constant and Ornstein–Uhlenbeck process. Left panels show the burst, decay and delay response kernels. The nine middle panels illustrate spike train patterns for the different combinations of response kernels and stimuli. The patterns produced by each response kernel are apparent; the bursts of spikes for the burst kernel, the firing rate adaptation of the decay kernel, and the refractory period by the delay kernel (no short ISIs). Likewise, the patterns produced by each stimulus are apparent; periodicity by the sinusoidal, abrupt changing intensities by the piecewise constant, and slowly fluctuating changes in intensity by the random stimulus
