Spatial localization and diffusion of Dirac particles and waves induced by random temporal medium variations by Seulong Kim, Kihong Kim

“…Numerical simulations reveal that narrow wave pulses evolve into Gaussian shapes, with their centers localizing and their widths growing indefinitely due to diffusive behavior. This universal phenomenon is independent of the initial pulse profile and the statistical properties of the random mass. …”

Cooperative behavior in a jump diffusion model for a simple network of spiking neurons by Roberta Sirovich, Laura Sacerdote, Alessandro E. P. Villa

“…In this study we analyze the ISI sequence --thespike train-- generated by a simple network of neurons whose outputactivity is modeled by a jump-diffusion process. We prove that,when specific ranges of the involved parameters are chosen, it is possible toobserve multimodal ISI distributions which reveal that the modelednetwork fires with more than one single preferred time interval.Furthermore, the system exhibits resonance behavior, withmodulation of the spike timings by the noise intensity. …”
