Inferring oscillatory modulation in neural spike trains
Fig 4
Spike trains without oscillatory modulation.
Simulated spike trains at 34Hz (A-D) and 60Hz (E-H), with 4 types of post-spike refractory profiles. Each panel shows Gibbs samples on left and on the right, an example spike train at the top, and the ISI histogram and spike history function as in Fig 1. The expected output of LOST is a nearly flat latent state, which is the case in A, B, D, E, G, H, accompanied by large variability in the other sampled parameters. In C and F, the amplitude of the latent state does not approach 0, but rather continues to fluctuate while taking larger values.
