Inferring oscillatory modulation in neural spike trains
Fig 2
LIF neuron with stimulus-triggered change in firing rate.
Phase inference for simulated LIF neuron driven by irregular oscillation with an average firing rate of 40Hz and a 15Hz modulating oscillation with OCV of 0.13. 60 trials of 1 second duration were used for LOST. A) Samples of the representative AR parameters. B) Top, samples of the TAE (cyan), the mean (red), and the empirical PSTH used to initialize TAE knot locations (green), and bottom, samples (cyan) of the spike history and mean (red). C) Example of inferred latent oscillation. The RL of the inferred oscillation is 0.65 ± 0.02, while the spike train has an R of 0.22 ± 0.01 with the ground truth oscillation.
