Inferring oscillatory modulation in neural spike trains
Fig 11
Two simultaneously-recorded motor cortical neurons: Simultaneous inference of theta oscillations using inferred slow fluctuation from Fig 10 as a known signal.
A) SP histograms for neurons 1 and 2 with circular statistics R = 0.13 ± 0.01 and 0.08 ± 0.01. B) power spectral densities of inferred oscillation for the 2 neurons showing power in the theta range. C) The cross-correlation function of the inferred latent oscillations of the two neurons, grey traces from when trials shuffled. D) The spike-spike cross correlation function shows very little oscillatory structure.
