Pattern discrimination and firing behavior of cold receptor model aided with noise
چکیده انگلیسی

A method for characterizing and identifying firing patterns of neural spike trains is presented. Three characteristic variables defined at sequential moments, including two formal derivatives and the integration of the counting process, are introduced to reflect the temporal patterns of a spike train. This paper also examines how noise interacts with encoding mechanisms of neuronal stimulus in a cold receptor. From ISI series and bifurcation diagrams it is shown that there are considerable differences in interval distributions and impulse patterns caused by purely deterministic simulations and noisy simulations. The ISI-distance can be used as an effective and powerful way to measure the noise effects on spike trains quantitatively. It is found that spike trains observed in cold receptors can be more strongly affected by noise for low temperatures than for high temperatures in some aspects; meanwhile, spike train has greater variability with the noise intensity increasing.


► We characterize spike trains of a cold receptor by three variables.
► The noise effect in the temperature encoding of neuronal spike trains is studied.
► Spike pattern can be more strongly affected by noise for different temperatures.
► Spike train has greater variability with the noise intensity increasing.
