From: Shifting Spike Times or Adding and Deleting Spikes—How Different Types of Noise Shape Signal Transmission in Neural Populations

Fig. 2

Two neurons are driven by a strong common noise ξ, a weak common signal s, and independent noise processes . a Addition and deletion of spikes: Independent noise processes lead to addition and deletion of spikes by weakly modulating the threshold value in Eq. (11) independently for both neurons. The first arrow indicates the deletion of a spike, the second arrow indicates the addition of a spike, and arrows three and four indicate time bins where there is no change in the spike trains. b Spike time shifting: Independent noise leads to shifting of spikes by weakly modulating the integrand in Eq. (16) independently for both neurons, but no spikes are added or deleted. The arrows exemplify corresponding spikes in the two spike trains that have been shifted in time
